Selection strategies for identifying fast cooking, mineral-biofortified bean cultivars with high agronomic performance

Environmental variability in indirect selection for grain yield in common bean lines

“…A significant genotype effect was observed for nine of the 17 traits evaluated (Table 1), evidencing the existence of genetic variability between the common bean lines and cultivars for most of the agronomic traits. Broad genetic variability for plant architecture and yield traits has been described for common bean genotypes (Arteaga et al, 2019;Boros et al, 2014;Delfini et al, 2017;Moura et al, 2013;Nadeem et al, 2020;Ribeiro et al, 2022;Soltani et al, 2016). However, ten traits exhibited a significant genotype × environment interaction effect, which evidences that the common bean genotypes showed variation for most plant architecture and yield traits when grown in different environments, thereby confirming previously published results (Arteaga et al, 2019;Boros et al, 2014;Delfini et al, 2017;Moura et al, 2013;Nadeem et al, 2020;Ribeiro et al, 2018Ribeiro et al, , 2022Soltani et al, 2016).…”

These results suggest that taking into consideration the environmental variability between growing seasons and years in the exact location where the experiments were conducted can increase the efficiency of indirect selection for grain yield in common bean lines.…”

Simultaneous selection for architectural and yield traits in common bean lines considering environmental variability

“…The use of selection indices has allowed simultaneous selection for several agronomic, technological, and/or nutritional traits in common bean (BERTOLDO et al, 2010;JOST et al, 2012;MAZIERO;STORCK, 2015;ARNS et al, 2018;RIBEIRO et al, 2018aRIBEIRO et al, ,b, 2022SILVA et al, 2018;DIAS et al, 2020) and snap bean (MARINHO et al, 2014;GOMES et al, 2018). However, the multiplicative index was considered a promising strategy for simultaneous selection in common bean, as it allowed attaining higher total and/or individual genetic gain values with a sign and magnitude favorable to the selection objectives compared with other selection indices (JOST et al, 2012;MAZIERO;STORCK, 2015;RIBEIRO et al, 2022). Nonetheless, some studies reported the difficulty in obtaining favorable individual genetic gain for all evaluated traits, but this fact did not constitute an impediment to the simultaneous selection of superior agronomic traits in common bean lines (BERTOLDO et al, 2010;RIBEIRO et al, 2018aRIBEIRO et al, ,b, 2022.…”

“…Caatinga, Mossoró, v. 36, n. 2, p. 362 -371, abr. -jun., 2023 objectives of selection of superior common bean lines when compared with other selection indices (JOST et al, 2012;MAZIERO;STORCK, 2015;RIBEIRO et al, 2022). It is also important to emphasize that the multiplicative index does not require establishing economic weights (SUBANDI; COMPTON;EMPIG, 1973), which simplifies calculations and the interpretation of results.…”
