Abstract This study evaluated the effects of ora-pro-nobis (Pereskia aculeate) flour supplementation on the in vivo basal antioxidant system of Drosophila melanogaster, and its action on the neural modulation observed by the enzyme acetylcholinesterase (AChE). The flies will receive a standard diet with flour incorporated at 5, 10 and 20% for 7 days. There was no change in food consumption, body weight, protein thiol levels and negative geotaxis behavior. The flies showed a reduction in the basal production of reactive species at concentrations of 10 and 20%, while there was a reduction in lipid peroxidation and catalase activity at all concentrations, accompanied by an increase in the levels of non-protein thiols. Superoxide dismutase activity was reduced in the 5 and 20% groups, while the reduction of superoxide anion in the 10% group may have contributed to the increase in longevity also in the 10% group. Longevity increased in groups 5 and 10%. The open field test may be related to the reduction in AChE activity in the 5, 10 and 20% groups. In general, the data show that supplementation with ora-pro-nobis flour at the concentrations tested did not cause toxicity and modulated the cholinergic system, demonstrating a therapeutic potential. orapronobis ora pro nobis Pereskia aculeate melanogaster AChE. .

A variabilidade genética de 32 linhagens de feijão de grãos especiais foi investigada para produtividade de grãos, massa de 100 grãos, tempo de cozimento e concentração de minerais nos grãos, e o índice Z foi usado para a seleção de linhagens com superioridade para a maioria dos caracteres. As linhagens IAC Centauro, IAC Galante, Xamego, Ouro Branco, Montcalm e Hooter apresentaram alta produtividade de grãos, reduzido tempo de cozimento (menor do que 24 min) e alta concentração de potássio (>14 g kg-1de matéria seca [MS]), cálcio (>1,42 g kg-1MS), ferro (>97,60 mg kg-1MS), zinco (>29,05 mg kg-1MS) e cobre (>8,67 mg kg-1MS), e seu uso na dieta é recomendado. A linhagem Cal-96 tem maior índice Z para produtividade de grãos e para a maioria dos minerais, e seu uso é recomendado para cruzamentos para o desenvolvimento de linhagens superiores.

Genetic variability of 32 inbred special grains bean lines was investigated for grain yield, mass of 100 grains, cooking time, and mineral concentrations in grains, and Z index was used for selection of superior lines in most of the characters. IAC Centauro, IAC Galante, Xamego, Ouro Branco, Montcalm, and Hooter lines presented high yield grain, short cooking time (less than 24 min), and high potassium (>14 g kg-1dry matter [DM]), calcium (>1.42 g kg-1DM), iron (>97.60 mg kg-1DM), zinc (>29.05 mg kg-1DM) and copper (>8.67 mg kg-1DM) concentrations, and their dietary use is therefore recommended. Cal-96 line presents higher Z index for grain yield and for the most of the minerals, and its use is recommended for crosses for the development of superior lines.

A seleção combinada para produtividade de grãos, qualidade de cozimento e nutricional é importante para o melhoramento de feijão comum (Phaseolus vulgaris L). Portanto, foram objetivos deste trabalho avaliar a variabilidade genética das linhagens de feijão comum quanto à produtividade de grãos, o tempo de cozimento e a concentração de minerais nos grãos, estudar a associação linear entre esses caracteres e utilizar o índice <img src="/img/revistas/rca/v44n4/a25simb.jpg" width="19" height="16"> para selecionar as linhagens avançadas com superioridade para a maioria dos caracteres. Para tanto, foram avaliadas 16 linhagens de feijão comum em duas épocas de cultivo. Os dados obtidos foram submetidos à análise de variância e de correlação de Pearson e o índice <img src="/img/revistas/rca/v44n4/a25simb.jpg" width="19" height="16"> foi estimado. As linhagens apresentaram variabilidade genética para a produtividade de grãos, o tempo de cozimento e a concentração de cálcio e de ferro nos grãos. Estimativas de correlação de baixa magnitude foram obtidas entre a produtividade de grãos e as concentrações de potássio (r = -0,3497), de zinco (r = 0,3486) e de cobre (r = 0,2729). A linhagem Gen Pr 14-2-3 apresenta maior índice <img src="/img/revistas/rca/v44n4/a25simb.jpg" width="19" height="16"> para produtividade de grãos, tempo de cozimento e concentração de potássio, ferro, zinco e cobre nos grãos, sendo indicada para hibridação controlada em programas de melhoramento de feijão para biofortificação.

Combined selection for grain yield, cooking and nutritional quality is important in the improvement of the common bean (Phaseolus vulgaris L). The objectives of this study therefore were to evaluate the genetic variability of the common bean lines as to grain yield, cooking time and the minerals concentration in the grains, to study the linear association between these characteristics and use the <img src="/img/revistas/rca/v44n4/a25simb.jpg" width="19" height="16"> index to select those advanced lines which are superior in most of these characteristics. To do this, 16 common bean lines were evaluated in two growing seasons. The data were subjected to variance analysis and the Pearson correlation, and the <img src="/img/revistas/rca/v44n4/a25simb.jpg" width="19" height="16"> index was then estimated. The lines presented genetic variability for grain yield, cooking time and calcium and iron concentrations in the grains. Low values for the correlation estimates were found between grain yield and concentrations of potassium (r = -0.3497), zinc (r = 0.3486) and copper (r = 0.2729). The Gen Pr 14-2-3 line presents the highest <img src="/img/revistas/rca/v44n4/a25simb.jpg" width="19" height="16"> index for grain yield, cooking time and concentrations of potassium, iron, zinc and copper in the grains, being recommended for controlled hybridization in common bean breeding programs for biofortification.
