ABSTRACT. Evaluation of combined ability can eliminate lines that are inefficient and enable the subsequent program steps to be more successful. The objective of this study was to predict the general (gi) and specific (sij) combination ability of popcorn S1 progenies for early selection. A total of 288 topcrosses were performed under a randomized complete block design with two replicates at two sites (Campinas and Capão Bonito, São Paulo State, Brazil). Diallel analyses were performed using mixed models and the maximum likelihood restricted/best unbiased linear prediction method. Evaluated traits included grain yield (GY; kg ha-1), weight of 100 grains (g), and popping expansion (PE; mL g-1). Ear components were also evaluated, including ear length, ear diameter (cm), and the number of grain rows (unit). The S1 progeny 32 presented the highest gi for GY in Campinas, whereas progeny 46 presented the highest gi for GY in Capão Bonito. The S1 progeny, 114 was an important parent for the popcorn breeding program, because it presented high gi for the traits of agronomic interest at both sites. Combination 86×IAC12 exhibited a high sij, and the 86 parent presented the second-highest gi for PE in Campinas, and it should be used for high PE genotypes.

Abstract IAC Nuance and IAC Tigre are special common bean cultivars for consumption in Brazil and for international markets. IAC Nuance has a 75-day cycle, with cranberry type rajado (streaked/dappled) bean seeds. IAC Tigre has 85-day cycle, a cream-colored seed coat with brown specks (pinto bean type). These cultivars are moderately resistant to anthracnose, angular leaf spot, fusarium wilt, common bacterial blight, and bacterial wilt.

Abstract IAC 1849 Polaco is a common bean cultivar with a carioca (beige/cream-colored with brown stripes) seed coat, 75-day mean maturity , semi-upright plant architecture, tolerance to seed darkening, mean 1000-seed weight of 240 grams, resistance to the main diseases in common bean, and mean seed yield of 2464 kg ha-1 obtained in 18 experiments.

Abstract IAC 1850 is a common bean cultivar with a carioca (beige-colored with brown stripes) seed coat, average cycle of 88 days, semi-upright plant architecture, tolerance to seed coat darkening, 1000 seed weight of 280 grams, resistance to the main diseases in common bean, and a high average yield (2,857 kg ha-1) obtained in 36 experiments conducted in different regions in Brazil.

Abstract IAC Sintonia, new common bean cultivar, was developed to incorporate moderate resistance to the main pathogens Fusarium oxysporum and Colletotrichum lindemuthianum allied to great grain yield observed, 5,750.00 kg ha-1. IAC Sintonia has semi-upright architecture and indeterminate growth habit (Type II), cycle is around 90 days and, 1000 seed weight of 280 grams.

RESUMO Plantar novos tipos de tangerinas é uma alternativa interessante para os citricultores brasileiros, devido ao crescente mercado interno. Assim, o objetivo deste estudo foi avaliar uma nova variedade de tangerina, a Fremont. A qualidade física e química da fruta e do suco (massa, cor da casca, rendimento de suco, acidez, teor de sólidos solúveis e ratio) foi avaliada, seguido por testes sensoriais para ordenar a diferença e preferência em relação às variedades clementina Nules e tangerina Ponkan. A tangerina Fremont produz frutos que atendem aos padrões exigidos pelo mercado consumidor brasileiro, com massa apropriada para a venda como fruta fresca, rendimento de suco adequado, maturação precoce a meia-estação. Além disso, teve a preferência, junto com a clementina Nules, quando comparado com a tangerina Ponkan, a principal variedade comercial no Brasil.

ABSTRACT Planting new types of tangerines is an interesting alternative for Brazilian citrus growers due to the increasing domestic market. Thus, the aim of this study was to evaluate a less exploited variety of tangerine, the Fremont. The physics and chemical quality of the fruit and juice (mass, peel color, juice yield, acidity, soluble solids and maturation index) was evaluated, followed by sensory testing for ranking of difference and preference to Nules clementine and Ponkan tangerine varieties. The Fremont tangerine produces fruits that meet the standards required by the Brazilian consumer market, with an appropriate mass for sale of the fresh fruit, a suitable juice yield, and early to mid-season maturation. Furthermore, et the preference, together with the Nules clementine, when compared to the Ponkan tangerine, wich is the main commercial variety in Brazil.

In the state of São Paulo, common bean is an important crop and the Agronomic Institute (Instituto Agronômico - IAC) registered the "carioca" (beige with brown stripes) bean cultivar IAC Imperador in the MAPA/RNC, exhibiting mean yield of 2,266 kg/ha in the 17 environments evaluated, a 75-day cycle, resistance to soil diseases and high quality seeds.
