“…The estimates of selective accuracy (SA) for these traits were considered to be of moderate to high magnitude, ranging from 0.61 to 0.73 for FeC and from 0.74 to 0.75 for ZnC, confirming the good discrimination capacity of the treatments. These results were similar to those obtained by Di Prado et al (2019), Martins et al (2016), Pereira et al (2014) and Silva et al (2012).…”

“…The heritability estimates for 100 seed weight were of high magnitude: 94% (80 to 97%) (Table 4), as reported in other studies (Alvares et al 2016;Di Prado et al 2019;Melo et al 2004), indicating high possibility of success from selection. For grain yield, heritability was 73%, which was considered above average, since this trait normally has lower heritability (Ramalho et al 2012).…”

“…For ZnC, similar results have been reported in the literature (Blair et al 2010;Ribeiro et al 2008). For 100 seed weight, this interaction does not always appear (Di Prado et al 2019). For FeC, interaction was not detected, which diverges from what is normally reported in the literature (Araújo et al 2003;Martins et al 2016).…”

The iron concentration (FeC) and zinc concentration (ZnC) in common bean grain are quantitative traits, and appropriate breeding techniques are required to achieve genetic gain. The aim of this study was to obtain a recurrent selection population of black bean to increase the FeC and ZnC in the grain and to select the superior progenies for formation of the next cycle and obtain lines. The base population was formed by crosses among ten parents. A total of 351 progenies were obtained, and, after two generations of selection, the 27 best progenies were evaluated in two field trials for FeC, ZnC, 100 seed weight and yield. Analyses of variance were carried out and genetic parameters were estimated. The heritability estimates ranged from 59 to 94% for the four traits. The estimates of expected gain from direct selection for each trait (3 to 21%) and simultaneous selection (1 to 4%) indicate success from selection. The eight progenies, selected based on simultaneous selection, have superior mean values, including to those of 'BRS Supremo' (10% for FeC, 8% for ZnC, 5% for 100 seed weight and 3.8% for yield), the Brazilian black bean cultivar with the highest FeC and ZnC. The recurrent selection population shows high genetic variability and potential for obtaining lines superior to the cultivars currently on the market, allying high agronomic performance and high FeC and ZnC in the grain. Furthermore, this population shows potential for generating a new recurrent selection cycle, from recombination of the eight superior progenies.

“…This allows gains from selection and a simultaneous increase in mineral concentration in the grain (Beebe, Gonzalez, & Rengifo, 2000;Blair et al, 2010). In addition, it is possible to aggregate these traits to good yield and other agronomic traits of interest (Di Prado et al, 2019;Martins et al, 2016;Ribeiro, Mambrin, Storck, Prigol, & Nogueira, 2013). In addition to increasing Fe and Zn concentrations in common bean, studies indicate possibilities of increasing protein and fiber concentration, as well as reducing grain cooking time (CT), one of the main indicators of technological quality.…”

“…Nutritional quality was evaluated by the concentrations of Fe (FeC), Zn (ZnC), crude fiber (CF), and crude protein (CP); technological quality was evaluated by CT; and commercial quality was evaluated by SY, 100GW, and grain yield. The FeC and ZnC were measured in 50 bean grains from each plot, according to Di Prado et al (2019). For CF, 20 g of grain from each plot was used through the acid-base digestion method adapted from the AOAC (1997).…”

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.

Genetic parameters and selection of common bean lines with high nutritional and agronomic quality

et al. 2022

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. INTRODUCTIONCommon (dry, edible) bean (Phaseolus vulgaris) is one of the main crops grown and consumed in Brazil, representing the Abbreviations: 100SW, 100-seed weight; ALS, reaction to angular leaf spot; AN, reaction to anthracnose; ARC, plant architecture; BLUP, best linear unbiased prediction; CFe, concentration of iron in the grain; CZn, concentration of zinc in the grain; GA, grain appearance; LOD, plant lodging; REML, restricted maximum likelihood.
