ABSTRACT The genetic improvement of sour passion fruit has the main objective of obtaining genotypes with high fruit yield and quality. The determination of the ideal early selection is extremely relevant to reduce costs and time in the selection of promising genotypes for use in genetic improvement programs. In this context, this work aimed to determine the ideal selection phase through estimates of genetic parameters, phenotypic, genotypic correlations and analysis of repeatability. A total of 14 yellow passion fruit hybrids in Lençóis (Bahia State, Brazil) were evaluated in a randomized block design with five replications and nine agronomic traits from three harvests with five fruits evaluated per repetition. Genetic parameters, repeatability coefficient and phenotypic and genotypic correlations were estimated for each evaluation cycle. For most parameters, the traits changed according to the evaluation cycle. Most of the genetic parameters showed favorable genetic conditions for the selection in the first harvest. The correlations between the traits fruit weight, peel and seedless pulp weight, fruit length and diameter were more stable in the different harvests. Through the repeatability analysis based on the principal components of covariance and correlation, it was possible to estimate a sample of 13 fruits per hybrid for prediction with accuracy of 90% for the physical traits of sour passion fruit.

Resumo: O objetivo deste trabalho foi avaliar tipos de estacas, concentrações de ácido indolbutírico (AIB) e substratos de cultivo, no enraizamento de cultivares de maracujá (Passiflora edulis), e comparar o desempenho inicial de estacas floríferas conduzidas em sistema de espaldeira ou no método de cultivo rasteiro em solo protegido com cobertura de plástico. Avaliaram-se as cultivares de maracujá BRS Gigante Amarelo, Isla Redondo Amarelo e FB 200 Yellow Master. Os tratamentos avaliados foram: estacas herbácea ou lenhosa, cinco concentrações de AIB (0, 500, 1.000, 2.000 e 4.000 mg L-1); e os substratos de cultivo casca de pinheiro ou espuma fenólica. Em campo, o crescimento inicial, a produção de frutos e a severidade da bacteriose foram avaliados em plantas de estacas competentes para florescer e em mudas, tanto no sistema em espaldeira como no método rasteiro em solo com cobertura de plástico. Para as cultivares avaliadas, observou-se alta taxa de enraizamento (>90%) tanto para as estacas herbáceas como para as semilenhosas, em substrato de espuma fenólica ou casca decomposta de pinheiro, independentemente da concentração de AIB. No sistema de espaldeira, após 14 meses de cultivo, a produção foi 45% maior para plantas obtidas de estacas que para mudas. As plantas rasteiras apresentaram baixo número de flores e frutos e grande severidade de bacteriose conforme a cultivar utilizada. As cultivares avaliadas podem ser propagadas por estaquia herbácea ou semilenhosa, em espuma fenólica ou em casca de pinheiro decomposta, sem aplicação de AIB. As estacas floríferas apresentam potencial para antecipar a produção em cultivo de maracujá-amarelo em espaldeira.

Abstract: The objective of this work was to evaluate types of cuttings, indole-3-butyric acid (IBA) concentrations, and potting media on the rooting of passion fruit (Passiflora edulis) cultivars, and to compare the initial performance of flowering-competent cuttings cultivated in a trellising system or in a nonstaking method on ground covered with plastic mulch. The passion fruit cultivars evaluated were BRS Gigante Amarelo, Isla Redondo Amarelo, and FB 200 Yellow Master were evaluated. The assessed treatments were: softwood or semi-hardwood cuttings; five concentrations of IBA (0, 500, 1,000, 2,000, and 4,000 mg L-1); and the pine bark or phenolic foam potting media. Initial growth, fruit yield, and bacteriosis severity were evaluated in the field in flowering-competent cuttings and seedlings, both in the trellising system and in the nonstaking method on mulched ground. For the evaluated cultivars, a high rooting rate (>90%) was observed for both softwood and semi-hardwood cuttings grown in phenolic foam or decomposed pine bark for potting media, regardless of the IBA concentration. In the espalier system, 14 months after transplanting, fruit yield was 45% higher for cuttings than for seedlings. Unstaked plants had a low number of flowers and fruit set, and a great damage by bacteriosis according to the used cultivar. The evaluated cultivars can be propagated either by softwood or semi-hardwood cuttings, in phenolic foam or decomposed pine bark, without IBA application. Flowering-competent cuttings have the potential to anticipate the production in the trellised cultivation of yellow passion fruit.

Resumo A propagação da maioria das espécies de maracujá (Passiflora spp.) utilizadas para fins alimentares é feita por via sexuada, embora a propagação assexuada, a exemplo de mudas obtidas por estaquia, enxertia ou cultura de tecidos também seja possível e muito útil em muitos casos. Neste trabalho, são apresentadas informações sobre os avanços científicos e tecnológicos na propagação sexuada e assexuada do maracujazeiro, considerando os diferentes métodos de propagação e suas aplicações. Novas demandas para as ações de pesquisa e desenvolvimento também são levantadas, considerando as diferentes espécies de maracujá e suas potencialidades de uso alimentar, ornamental e medicinal.

Abstract The propagation of many passion fruit species (Passiflora spp.) is done by seeds or sexual method, although asexual propagation, such stem cuttings, grafting or tissue culture is also possible and very useful in many cases. In this work, it was presented information on scientific and technological advances in sexual and asexual propagation of passion fruit, considering the different propagation methods and their applications. New demands for research and development activities are also related, given the wide range of passion fruit species and its potential for food, ornamental and medicinal use.

Resumo Avaliaram-se produção e qualidade de frutos de maracujazeiros-amarelos e doces na região norte do Estado de São Paulo, incluindo-se as cultivares FB200 Yellow Master, Isla Redondo Amarelo, BRS Rubi do Cerrado, BRS Sol do Cerrado e BRS Gigante Amarelo, os hibridos intraespecíficos de maracujazeiro-amarelo GP09-02, GP09-03, H09-09, H09-14, HFOP- 08 e HFOP-09, e duas seleções de maracujazeiro-doce, BGP DG e BGP DP. O delineamento experimental foi em blocos casualizados, com 13 tratamentos, cinco repetições e três plantas na parcela. O maracujazeiro-doce BGP DG foi selecionado para mercado de frutas frescas, em função da elevada produtividade (52,7 t ha-1) e da maior massa e tamanho de fruto (243 g). Entre os maracujazeiros-amarelos, o híbrido GP09-02 destacou-se pelo maior número acumulado de frutos por planta, em dois anos de cultivo, embora GP09-02, H09-09, BRS Sol do Cerrado, Isla Redondo Amarelo e FB200 tenham apresentado maior rendimento de suco, em média 32,3%, e produtividade acumulada por área semelhante. Todos os frutos apresentaram elevada concentração de sólidos solúveis, maior nos maracujás-doces (20,0 °Brix) em relação aos amarelos (média de 14,28 °Brix). Essas cultivares, híbridos e seleções apresentam potencial de cultivo no norte do Estado de São Paulo e em regiões com condições edafoclimáticas similares.

Abstract Yield and quality of yellow and sweet passion fruits produced in northern state of São Paulo, Brazil were evaluated, including FB200 Yellow Master, Isla Redondo Amarelo, BRS Rubi do Cerrado, BRS Sol do Cerrado and BRS Gigante Amerelo cultivars, GP09-02, GP09-03, H09- 09, H09-14, HFOP-08 and HFOP-09 intraspecific hybrids, and two selections of sweet passion fruits, BGP DG and BGP DP. Experimental design was comprised of randomized blocks with 13 treatments, five replicates and three plants per plot. BGP DG was the sweet passion fruit selected for fresh fruit market as a result of its higher yield (52.7 t ha-1) and fruit size and mass (243 g). Among yellow passion fruits, GP09-02 stood out because it showed the highest number of fruits per plant after two years of cultivation, even though GP09-02, H09-09, BRS Sol do Cerrado, Isla Redondo Amarelo and FB200 had also presented higher juice content, on average 32.3%, and equivalent accumulated fruit yield. All fruits had high soluble solids contents, with higher concentration for sweet passion fruits (20.0 °Brix) than yellow passion fruits (average of 14.28 °Brix). These cultivars, hybrids and selections have potential for cultivation in northern state of São Paulo and in regions with similar edaphoclimatic conditions.

Abstract The aim of this study was evaluate the physical and physico-chemical characteristics of extracted fruit pulp of passion fruit with different skin color (yellow, light and dark purple) under refrigeration temperatures and storage times. The extracted pulp of passion fruit was stored at different temperatures: 10 °C, 25 °C; - 30 °C and - 80 °C and at four different storage periods: 0; 10; 20 and 30 days. The following physical and physico-chemical characteristics of the fruit were evaluated: color of fruit peel, fruit weight, diameter, length and width of the fruit, peel thickness, peel mass, pulp mass, pulp color, juice yield, pH, soluble solids, titratable acidity and ratio. The physical and physico-chemical results indicate that all the passion fruit pulp, in natura as well as refrigerated, presented values in conformity to the identity and quality standards. The coloration of the fruit peel influenced the preservation of pulp color during the storage period and conditions. Purple fruits showed no change in the color of the pulp, even under different conservation procedures. The passion fruit pulp can be stored up to 30 days while preserving the physical and physico-chemical characteristics, similar to the pulp in natura.

Abstract The objective of this study was to evaluate the stability and adaptability, using the method of harmonic means of the relative performance of genetic values and to estimate the genetic components of variance and average via mixed models of 14 genotypes of passion fruit in three environments. Data were obtained in a random block design with three replicates and nine plants per plot. For the hybrids in the final validation phase, the estimates of heritability and genetic gains in the evaluated environments showed good prospects for selection of superior genotypes. There was a pronounced effect of genotype-environment interaction (GxE) for all traits investigated except fruit length, percentage of pulp, soluble solids, titratable acidity and SS/TA ratio. The most stable and adaptable hybrids in the evaluated environments were BRS Gigante Amarelo, HFOP-09, H09-09, GP09-02, GP09-03 and BRS Sol do Cerrado.

RESUMO O objetivo deste trabalho foi avaliar a emergência e crescimento inicial de plantas de Passiflora spp. com sementes obtidas de frutos em diferentes estádios de maturação e tratadas com diferentes concentrações de ácido giberélico (GA3). As espécies avaliadas foram Passiflora alata, P. cincinnata, P. setacea, P. edulis e P. gibertii. No primeiro ensaio as sementes utilizadas foram extraídas de frutos em diferentes estádios de maturação e semeadas em sacos de polietileno no delineamento inteiramente casualizado em esquema fatorial 4 x 3 (espécie x estádio de maturação) com cinco repetições. Um segundo e terceiro experimentos avaliaram respectivamente sementes armazenadas por 11 meses e sementes coletadas de frutos recém-colhidos das mesmas espécies, imersas em solução de GA3 (0; 250; 500 e 1.000 mg L-1) e transferidas para substrato agrícola. O delineamento experimental foi em blocos ao acaso, em esquema fatorial 5 x 4 (espécie x concentração de GA3), com quatro blocos e vinte e cinco sementes por parcela, para análise da emergência. Frutos a partir do estádio "de vez" podem ser colhidos para P. cincinnata, P. alata, P. edulis e P. setacea, sem prejuízo da qualidade fisiológica das sementes. A solução de GA3 até 1.000 mg L-1 não incrementou a emergência e o crescimento inicial de plantas de Passiflora spp. armazenadas por 11 meses. Sementes obtidas de frutos maduros recém-colhidos de Passiflora spp. apresentam emergência mais alta e mais rápida, e crescimento inicial de plantas, após imersão em solução de GA3 entre 500 e 1.000 mg L-1.

ABSTRACT The aim of this work was to evaluate emergence and initial growth in plants of Passiflora spp. from seeds obtained from fruit at different stages of maturation and treated with different concentrations of gibberellic acid (GA3). The species under evaluation were Passiflora alata, P. cincinnata, P. setacea, P. edulis and P. gibertii. For the first trial, the seeds were extracted from fruits at different stages of maturation, and sown in polyethylene bags in a completely randomised design with a 4 x 3 factorial scheme (species x stage of maturation), with five replications. A second and third experiment evaluated respectively, seeds stored for 11 months and seeds collected from freshly picked fruit of the same species, immersed in a solution of GA3 (0, 250, 500 and 1000 mg L-1) and transferred to an agricultural substrate. The experimental design was of randomised blocks in a 5 x 4 factorial scheme (species x GA3 concentration), with four blocks and twenty-five seeds per lot to analyse emergence. In P. cincinnata, P. alata, P. edulis and P. setacea, fruit at the pre-ripe stage can be harvested with no harm to the physiological quality of the seeds. A solution of GA3 up to 1000 mg L-1 did not increase emergence or initial growth in plants of Passiflora spp. stored for 11 months. Seeds from ripe, freshly picked fruit of Passiflora spp. display greater and faster emergence, and greater initial plant growth after soaking in a 500 to 1,000 mg L-1 solution of GA3.

RESUMO: Avaliou-se a enxertia hipocotiledonar de maracujazeiro azedo em porta-enxertos de Passiflora alata, P. edulis, P. cincinnata e P. gibertii utilizando-se, como fixadores para envolvimento da região da enxertia, fita adesiva tipo crepe, grampo metálico de cabelo e grampo de enxertia a mola. O delineamento experimental foi em blocos ao acaso, em esquema fatorial 4 x 3 (porta-enxerto x fixador), com 12 tratamentos, três repetições e oito plantas na parcela. Utilizou-se a enxertia hipocotiledonar pelo método de garfagem de topo em fenda cheia. Avaliaram-se diâmetro de caule, altura de planta e número de folhas do porta-enxerto no momento da enxertia, percentagem de sobrevivência da enxertia, diâmetro do caule, número de folhas e altura do enxerto aos 30, 60 e 90 dias após a enxertia. A sobrevivência do enxerto de maracujazeiro azedo foi elevada, em geral, sendo equivalente para todos os porta-enxertos avaliados, demonstrando a eficiência da técnica. O uso dos fixadores de enxertia resultou em elevada percentagem de sobrevivência dos enxertos sem se verificarem diferenças entre os fixadores. Aos 90 dias após a enxertia, o maracujazeiro azedo, enxertado em P. alata apresentou menor crescimento em relação àqueles enxertados em P. edulis e P. gibertii.

ABSTRACT: The hipocotyledonar grafting of yellow passion fruit was evaluated onto Passiflora alata, P. edulis, P. cincinnata and P. gibertii with masking tape, metallic hair clip and spring plastic graf clip as tying materials. Experimental design was randomized blocks in a factorial 4 x 3 (rootstock x tying material) with 12 treatments, three replications and eight plants in the unit. The hipocotyledonar grafting method utilized was apical cleft grafting. Collected data included stem diameter, plant height and leaf number of rootstocks at grafting, and graft survival rate, stem diameter, leaf number and height 30, 60 and 90 days after grafting. Graft survival rate was high in general and equivalent among the evaluated rootstocks, indicating that apical cleft hipocotyledonar grafting was an efficient technique. All tying materials led to similar graft survival rates. Yellow passion fruit grafted onto P. alata presented lower canopy growth in relation to plants grafted onto P. edulis and P. gibertii, 90 days after grafting.

RESUMO A enxertia do maracujazeiro azedo em outras espécies de Passiflora spp. pode ser uma alternativa para a produção sob estresses bióticos, notadamente doenças do sistema radicular. Este trabalho avaliou a reação à fusariose de maracujazeiro azedo enxertado em P. edulis, P. alata, P. gibertii e P. cincinnata em condições de campo em Cruz das Almas, BA. O desempenho agronômico foi avaliado pelo crescimento, florescimento e produção de frutos até 13 meses após o plantio. A enxertia foi do tipo garfagem hipocotiledonar de topo em fenda cheia. Procedeu-se à análise de sobrevivência à fusariose ao longo do período de avaliação, baseando-se em sintomas visuais da doença. A enxertia em espécies de passifloras silvestres não alterou o diâmetro do caule nem a frutificação do maracujazeiro azedo, embora o florescimento de P. edulis enxertado em P. alata tenha sido inferior ao observado em P. edulis enxertado em si mesmo. A enxertia hipocotiledonar de P. edulis em P. gibertii, P. cincinnata e P. alata resultou em sobrevivência à fusariose similar às plantas enxertadas em P. edulis até 13 meses após o plantio a campo.

ABSTRACT Yellow passion fruit grafting on other Passiflora spp. may be an alternative technique for the production under biotic stresses, especially soil-borne diseases. This study evaluated the survival of yellow passion fruit to fusariosis grafted onto P. edulis, P. alata, P. gibertii and P. cincinnata, in the field in Cruz das Almas, State of Bahia, Brazil. Horticultural performance was evaluated as plant growth, flowering and fruit set up to 13 months after transplanting. The apical cleft hipocotyledonar grafting was used. Survival analysis to fusariosis was based on the detection of typical visual symptoms. Grafting in species of wild passifloras did not influence on the stem diameter or fruit set of the yellow passion fruit, even though the flowering of P. edulis grafted on P. alata was lower than P. edulis grafted on itself. Hipocotyledonar grafting of P. edulis on P. gibertii, P. cincinnata and P. alata resulted in similar survival rates to fusariosis in relation to plants grafted onto P. edulis up to 13 months after transplanting.

High yield stability and adaptability of yellow passion fruit varieties (Passiflora edulis Sims. f. flavicarpa Deg.) are highly desirable attributes when exploring different environments. This study aimed to evaluate the adaptability and yield stability of yellow passion fruit varieties using AMMI (additive main effects and multiplicative interaction) and other ancillary statistics. Twelve varieties were evaluated in eight environments. Analysis of variance showed effects attributable to the varieties (G), environment (E) and their interaction (G × E). The first two multiplicative components of the interaction accounted for 69% of the sum of squares. The scores of the principal interaction components showed high variability for the environments relative to the variety effects. High varietal phenotypic stability was observed in three environments; which can be used in yellow passion fruit breeding programs for initial selection trials. A biplot-AMMI analysis and yield stability index incorporating the AMMI stability value and yield capacity in a single non-parametric index were useful for discriminating genotypes with superior and stable fruit yield. AMMI analysis also allowed for the identification of more productive varieties in specific environments, leading to significant increase in passion fruit productivity.

O uso de Passifloras como plantas ornamentais é recente, e por isso pouco se sabe sobre a possibilidade de cruzamento entre diferentes espécies, bem como sobre a viabilidade polínica. O objetivo do trabalho foi avaliar a viabilidade do pólen de seis espécies de maracujazeiro coletados em diferentes estádios de desenvolvimento fisiológico por meio da germinação in vitro, bem como via análise histoquímica, por meio do uso de corantes. O pólen foi coletado em três estádios (pré-antese, antese e pós-antese). Foram comparadas três composições de meios de cultura para avaliar a germinação in vitro, e para a análise histoquímica utilizou-se de dois corantes o 2,3,5-cloreto de trifeniltetrazólio (TTC) e o lugol. O meio de cultura contendo 0,03% de Ca(NO3).4H2O, 0,02% de Mg(SO4).7H2O, 0,01% de KNO3, 0,01% de H3BO3, 15% de sacarose, solidificado com 0,8% de ágar e pH ajustado para 7,0, proporcionou maior percentual de grãos de pólen germinados. O melhor momento de coleta do pólen com relação à melhor viabilidade e à germinação é na antese. O corante TTC e o lugol superestimaram a viabilidade de pólen, já que todos os acessos apresentaram índice de viabilidade alto, quando comparados aos resultados obtidos in vitro.

The use of Passiflora species for ornamental purposes has been recently developed, but little is known about pollen viability and the potential for crossing different species. The objective of this study was to evaluate the pollen viability of six Passiflora species collected from different physiological stages of development through in vitro germination and histochemical analysis using dyes. The pollen was collected in three stages (pre-anthesis, anthesis and post-anthesis). Three compositions of culture medium were used to evaluate the in vitro germination, and two dyes (2,3,5-triphenyltetrazolium chloride, or TTC, and Lugol's solution) were used for the histochemical analysis. The culture medium containing 0.03% Ca(NO3) 4H2O, 0.02% of Mg(SO4 ).7H2O, 0.01% of KNO3, 0,01% of H3BO3, 15% sucrose, and 0.8% agar, pH 7.0, showed a higher percentage of pollen grains germinated. Anthesis is the best time to collect pollen because it promotes high viability and germination. The Lugol's solution and TTC dye overestimated the viability of pollen, as all accessions showed high viability indices when compared with the results obtained in vitro.

The characterization and viability of pollen grains are useful tools to guide crosses in breeding programs. The objective of this study was to describe the morphological patterns and viability of pollen grains from five accessions of Passiflora edulis f. flavicarpa O. Deg. and five accessions of Passiflora setacea DC. Pollen morphology descriptions were made using light microscopy and scanning electron microscopy, whereas the viability analysis was performed by in vitro germination and histochemical analysis (Lugol's solution and 2,3,5-triphenyltetrazolium chloride). Pollen grains assessed for germination were inoculated in culture medium containing Ca(NO3).4H2O (0.03%), Mg(SO4).7H2O (0.02%), KNO3 (0.01%), H3BO3 (0.01%), sucrose (15%) and agar (0.8%). Although P. edulis and P. setacea showed the same shape and type of pollen aperture, the two differed in terms of their morphology and exine ornamentation pattern. In vitro analysis showed that one of the P. edulis f. flavicarpa accessions (designated BGP 330) presented the highest germination rate (53.98%) and longest pollen tube (2.18 mm). The histochemical analysis overestimated pollen viability when compared with the in vitro results. The results of this study contribute to the breeding of Passiflora species by increasing the understanding of their morphology and pollen grain viability.

The aim of this study was to evaluate the selected 41 SSR markers developed for yellow passion fruit (Passiflora edulis f. flavicarpa Sims.) for their transferability to 11 different Passiflora species. Twenty-one SSR were successfully amplified in 10 wild species of passion fruit producing 101 bands. All the markers were amplifiable for at least one species. The mean transferability was 68,8%, ranging from 15,4% (primer PE11) to 100 % (PE13, PE18, PE37, PE41 and PE88). Transferability was higher for the species from the Passiflora subgenus than for those from the Decaloba and Dysosmia subgenus. The results indicated a high level of nucleotide sequence conservation of the primer regions in the species evaluated, and consequently, they could potentially be used for the establishment of molecular strategies for use in passion fruit breeding and genetics.

This study aimed to characterize the resistance of 31 passion fruit (Passiflora sp.) genotypes to Fusarium oxysporum f. sp. passiflorae (FOP). About 20 seedlings of each genotype were inoculated by immersing the roots in a suspension of 10(6) macroconidia mL-1 for five minutes and then transplanting them into pots containing a mixture of soil and sterile substrate. They were evaluated daily for 120 days for the occurrence of wilt symptoms and death. These data were used to calculate the area under the disease progress curve, for survival analysis and grouping. The mortality rate ranged from 0 to 100% and the AUDPC ranged from 0 for genotypes without symptoms of the disease to 6,650.63 for the hybrid HFOP-01. Genotypes were classified into four subgroups: resistant, moderately resistant, susceptible and highly susceptible. The resistance was genotype dependent, but no significant variation was found between the purple and the yellow P. edulis.

O objetivo deste trabalho foi utilizar uma escala de severidade para algumas doenças do maracujazeiro, visando à identificação de fontes de resistência. Foram avaliados 75 acessos de Passiflora spp. em condições de campo, sob alta infecção natural dos patógenos, para a severidade da virose, nas folhas (VIFO), frutos (VIFR) e distribuição na planta (VIPL), bem como para verrugose nos frutos e ramos (VEFR e VERA, respectivamente) e antracnose nos frutos (ANFR). Houve alta variabilidade para resistência às doenças, embora poucos acessos tenham sido classificados como resistentes à VIFO, VIFR e VIPL, sendo que apenas um acesso de P. setacea (BGM237) foi considerado resistente aos três tipos de avaliações para virose. A maioria dos acessos de maracujazeiro- amarelo e roxo possui algum grau de suscetibilidade a um ou outro sintoma da virose. Quanto à VERA, acessos de P. alata e P. cincinnata foram mais resistentes, embora P. alata demonstre maior resistência a VEFR. Alguns acessos de P. edulis comportam-se como moderadamente resistente à VERA e VEFR. A maioria dos acessos de P. alata, P. cincinnata e P. setacea não apresentou sintomas de antracnose nos frutos. A escala de severidade adotada mostrou-se eficiente para a separação dos acessos de maracujazeiro em diferentes classes de resistência a doenças.

The objective of this study was to use a severity scale for some passion fruit diseases, in order to identify sources of resistance. Seventy-five accessions of Passiflora spp. were evaluated under field conditions and high natural infection of pathogens. Symptoms of virus severity in the leaves (VILE), fruits (VIFR) and distribution in the plant (VIPL), as well as scab on fruit and branches (SCFR and SCBR, respectively) and anthracnose in fruits (ANFR), were analyzed. High variability for disease resistance was observed, although few accessions were classified as resistant to VILE, VIFR and VIPL. Only BGM237 (P. setacea) was considered resistant of these three types of virus evaluation. The most of yellow and purple passion fruit accessions showed some degree of susceptibility to one or another virus symptom. P. alata and P. cincinnata were more resistant to SCBR, although P. alata showed more resistance to SCFR. Some accessions of P. edulis were moderately resistant to SCFR and SCBR. The majority of P. alata, P. cincinnata and P. setacea accessions do not showed symptoms of anthracnose in the fruits. The severity scale proposed was useful to separate the accessions of passion fruit in different classes of disease resistance.
