“…The high estimates of heritability for FeC, ZnC, CP, and CT indicate conditions favorable to breeding, with success in selection. Different ranges for heritabilities have been reported in the literature, most of them medium to high values: from 58 to 97% for FeC, from 45 to 97% for ZnC (Buratto & Moda‐Cirino, 2017; Silva, Abreu, Ramalho, & Maia, 2012), from 33 to 94% for CP (Londero, Ribeiro, Jost, & Cargnelutti Filho, 2008; Silva et al., 2008; Silva et al., 2012), and from 12 to 91% for CT (Baldoni & Santos, 2005; Bertoldo, 2008).…”

Effectiveness of breeding selection for grain quality in common bean

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.

“…The Bulk method with selection in the F 3 generation is commonly used in most breeding programs of bean (Raposo et al, 2000;Costa, Rava, & Zimmermann, 2002;Silva et al, 2008;Ramalho et al, 2012) and wheat (Wang et al, 2003). However, studies demonstrating the efficiency of this method in soybean crops are rare.…”

<b>Strategies to select soybean segregating populations with the goal of improving agronomic traits

et al. 2018

The success of breeding programs depends on selection procedures and on the breeding methods adopted for selecting segregating populations. The objective of this study was to evaluate the efficiency of the Bulk method with selection in the F3 generation (BulkF3) compared to that of Bulk method as well as determine the most effective selection strategy in terms of genetic gain. Twenty segregating populations were selected by two methods. The 60 best families of each method were selected according to their average agronomic performance. An augmented block design was used. The following agronomic traits were evaluated: insertion height of first pod, plant height at maturity, number of branches and of pods per plant, 100-seed weight, and grain yield. For comparison of the methods, genetic component estimates, genetic gain and predicted breeding values were calculated using mixed models (REML and BLUP). The results showed the families obtained with the BulkF3 method were more productive, showed suitable plant height, a larger number of branches and pods, and higher 100-seed weight. The BulkF3 method was found to be an effective selection strategy for soybean improvement.

“…The methods have been frequently compared in several crops, mainly for the trait of grain yield. For common beans, besides yield (Raposo et al, 2000), protein content was studied by Silva et al (2008) and fiber content by Silva (2009). In these cases, estimates of genetic parameters were utilized to aid in the comparison of the potential of selected progenies through different methods.…”

“…In research that evaluated the potential of biologic nitrogen fixation of segregant progenies, the bulk-population method was superior to SSD (Pereira and Braidotti, 2001). Silva et al (2008), evaluating the genetic potential of segregant populations created using the breeding methods of bulk-population, bulk within F 2, and SSD for grain bean protein content, concluded that enough genetic variability exists for selection and that the bulk-population method is more efficient in generating a greater number of progenies with superior averages.…”

ABSTRACT. Gastrointestinal health is of great importance due to the increasing consumption of functional foods, especially those concerning diets rich in fiber content. The common bean has been valorized as a nutritious food due to its appreciable fiber content and the fact that it is consumed in many countries. The current study aimed to evaluate and compare the genetic potential of common bean progenies of the carioca group, developed through different breeding methods, for crude fiber content. The progenies originated through hybridization of two advanced strains, CNFC 7812 and CNFC 7829, up to the F 7 generation using three breeding methods: bulk-population, bulk within F 2 families, and single seed descent. Fifteen F 8 progenies were evaluated in each method, as well as two check cultivars and both parents, using a 7 x 7 simple lattice design, with experimental plots comprised of two 4-m long rows. Field trials were conducted in eleven environments encompassing four Brazilian states and three different sowing times during 2009 and 2010. Estimates of genetic parameters indicate differences among the breeding methods, which seem to be related to the dif-V.A.P. Júnior et al. 5764©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (2): 5763-5774 (2015) ferent processes for sampling the advanced progenies inherent to each method, given that the trait in question is not subject to natural selection. Variability amongst progenies occurred within the three breeding methods and there was also a significant effect of environment on the progeny for all methods. Progenies developed by bulk-population attained the highest estimates of genetic parameters, had less interaction with the environment, and greater variability.
