The aim of common bean (Phaseolus vulgaris) breeding has always been to increase agronomic quality. Recently, the nutritional quality of the grain has been gaining importance. The aim of this study was to estimate genetic parameters for traits related to nutritional and agronomic quality and to select lines for an assessment stage in multiple environments and/or for use as new parents. Initially, 37 lines were evaluated in three environments for nine agronomic and nutritional traits. Of these lines, 15 stood out and were assessed in another five environments. The mixed model (restricted maximum likelihood–best linear unbiased prediction) procedure and multivariate analysis were adopted for processing the phenotypic data. There was genetic variability among the lines assessed for all the traits. The heritability estimates for the agronomic traits ranged from 29% for plant architecture to 94% for reaction to anthracnose. Heritability estimates for the nutritional traits were 77% for grain iron concentration and 79% for zinc concentration. Multivariate analysis, based on all the traits and on all the environments (eight), identified three groups of lines and allowed selection of the lines CNFC 18092, CNFC 18097, CNFC 18114, and BRS Sublime to carry out new crosses, for they showed specific superiority for some traits and the possibility of greater genetic diversity in the populations. The lines CNFC 18091, CNFC 18092, and CNFC 18106 were selected for assessment in experiments in multiple environments because they combine high agronomic and nutritional quality.

高营养农艺品质普通豆系的遗传参数及选择

菜豆（Phaseolus vulgaris) 育种一直是为了提高农艺品质。最近，谷物的营养品质越来越受到重视。本研究的目的是估计与营养和农艺质量相关的性状的遗传参数，并选择品系用于多种环境中的评估阶段和/或用作新亲本。最初，在三个环境中评估了 37 个品系的九个农艺和营养性状。在这些线路中，有 15 条脱颖而出，并在另外五个环境中进行了评估。采用混合模型（受限最大似然-最佳线性无偏预测）程序和多变量分析来处理表型数据。对所有性状进行评估的品系之间存在遗传变异性。农艺性状的遗传力估计范围从植物结构的 29% 到对炭疽病反应的 94%。营养性状的遗传力估计为谷物铁浓度为 77%，锌浓度为 79%。基于所有性状和所有环境（8 个）的多变量分析，确定了三组品系，并允许选择品系 CNFC 18092、CNFC 18097、CNFC 18114 和 BRS Sublime 进行新的杂交，因为它们显示出特定的某些性状的优势以及种群中更大遗传多样性的可能性。选择 CNFC 18091、CNFC 18092 和 CNFC 18106 品系在多种环境中进行实验评估，因为它们结合了高农艺和营养品质。营养性状的遗传力估计为谷物铁浓度为 77%，锌浓度为 79%。基于所有性状和所有环境（8 个）的多变量分析，确定了三组品系，并允许选择品系 CNFC 18092、CNFC 18097、CNFC 18114 和 BRS Sublime 进行新的杂交，因为它们显示出特定的某些性状的优势以及种群中更大遗传多样性的可能性。选择 CNFC 18091、CNFC 18092 和 CNFC 18106 品系在多种环境中进行实验评估，因为它们结合了高农艺和营养品质。营养性状的遗传力估计为谷物铁浓度为 77%，锌浓度为 79%。基于所有性状和所有环境（8 个）的多变量分析，确定了三组品系，并允许选择品系 CNFC 18092、CNFC 18097、CNFC 18114 和 BRS Sublime 进行新的杂交，因为它们显示出特定的某些性状的优势以及种群中更大遗传多样性的可能性。选择 CNFC 18091、CNFC 18092 和 CNFC 18106 品系在多种环境中进行实验评估，因为它们结合了高农艺和营养品质。确定了三组品系，并允许选择品系 CNFC 18092、CNFC 18097、CNFC 18114 和 BRS Sublime 进行新的杂交，因为它们在某些性状上表现出特定的优势，并且在种群中具有更大的遗传多样性的可能性。选择 CNFC 18091、CNFC 18092 和 CNFC 18106 品系在多种环境中进行实验评估，因为它们结合了高农艺和营养品质。确定了三组品系，并允许选择品系 CNFC 18092、CNFC 18097、CNFC 18114 和 BRS Sublime 进行新的杂交，因为它们在某些性状上表现出特定的优势，并且在种群中具有更大的遗传多样性的可能性。选择 CNFC 18091、CNFC 18092 和 CNFC 18106 品系在多种环境中进行实验评估，因为它们结合了高农艺和营养品质。
