The aims of this study were to investigate the genetic variability and the genotype × environment interaction for quality and yield traits in common bean (Phaseolus vulgaris L.), to evaluate the degree of informativeness of the evaluations of grain quality in only one environment, to estimate genetic parameters for grain quality traits, and to select lines with superior grain quality. We evaluated 81 carioca common bean lines in preliminary line trials in several environments for nutritional, technological, and commercial quality and selected the 20 superior lines, which were evaluated in validation trials in nine environments. Individual and combined ANOVAs were performed for all the traits. Correlations were estimated between Fe and Zn concentrations and yield; adaptability and phenotypic stability were analyzed; and superior genotypes were selected based on the Mulamba & Mock index. It is possible to increase the Fe, Zn, and crude protein concentrations and reduce cooking time; however, increasing crude fiber is a challenge. Preliminary evaluation of the quality traits in only one environment was effective and sufficient for selection of genotypes superior in Fe concentration, crude fiber, crude protein, and cooking time; and genetic gains can be obtained from selection for these traits. Genetic and phenotypic correlations were observed between Fe and Zn concentrations. The lines CNFC 16627, CNFC 16518, CNFC 16602, CNFC 16615, and CNFC 16520 are superior based on the selection index and are recommended for breeding for grain quality in carioca common bean.

蚕豆品质育种选择的有效性。

本研究的目的是研究普通豆(菜豆)的品质和产量性状的遗传变异性和基因型×环境互作。L.),仅在一种环境中评估谷物质量评估的信息程度,评估谷物品质性状的遗传参数,并选择品质优良的品系。在营养,技术和商业质量等多个环境的初步品系试验中,我们评估了81种木薯普通品系,并选择了20种优良品系,并在9种环境的验证试验中对其进行了评估。对所有性状进行单独的和组合的方差分析。估计了铁和锌的浓度与产量之间的相关性。分析适应性和表型稳定性;根据Mulamba&Mock指数选择了优良的基因型。可以增加铁,锌和粗蛋白的浓度并减少烹饪时间。然而,增加粗纤维是一个挑战。仅在一种环境中对品质性状进行初步评估,对于选择铁浓度,粗纤维,粗蛋白和烹煮时间优越的基因型是有效且充分的;从这些性状的选择中可以获得遗传增益。观察到铁和锌浓度之间的遗传和表型相关性。基于选择指数,CNFC 16627,CNFC 16518,CNFC 16602,CNFC 16615和CNFC 16520品系优良,建议用于木薯普通豆的籽粒品质育种。从这些性状的选择中可以获得遗传增益。观察到铁和锌浓度之间的遗传和表型相关性。基于选择指数,CNFC 16627,CNFC 16518,CNFC 16602,CNFC 16615和CNFC 16520品系优良,建议用于木薯普通豆的籽粒品质育种。从这些性状的选择中可以获得遗传增益。观察到铁和锌浓度之间的遗传和表型相关性。基于选择指数,CNFC 16627,CNFC 16518,CNFC 16602,CNFC 16615和CNFC 16520品系优良,建议用于木薯普通豆的籽粒品质育种。
