“…The higher estimate of broad sense heritability for BY was indicated by the black seed coat lines conducted by the bulk method (77.11%), a result similar to that reported by Jost et al (2014), indicating low environmental influence for BY. In relation to genetic variances, Silva et al (2013) evaluated common bean progenies obtained by the bulk method and found estimates of 29 769.6 and 11 591.5 kg ha -1 for BY, values superior to those found in this study, which ranged from 80.66 to 6266.34 kg ha -1 . According to Ramalho et al (2012), among the methods of conducting segregating populations, the bulk method stands out through maintaining variability among the lines selected, regardless of the generation in which sampling was carried out; the variability of the F2 generation populations was similar.…”

“…Rocha et al (2015) evaluated the yield of 48 carioca and black seed coat common bean progenies and reported broad sense heritability estimates ranging from 6.80% to 70.31%, results that are similar to those presented in this study. Silva et al (2013) compared lines obtained by the bulk and single seed descent (SSD) methods and found maximum values of broad sense heritability for BY of 49.8%. From the estimates of broad sense heritability presented in this study for the black seed coat lines in the bulk method and carioca seed coat lines in the genealogical method, it can be inferred that a favorable gain from selection is expected for BY.…”

“…Jost et al (2014) highlighted the genealogical method for obtaining common bean lines with high bean seed yield and an early cycle. Silva et al (2013) found that the bulk method, within F2, had the highest indexes of generating common bean progenies with better performance for bean seed yield and crude fiber content.…”

A common bean (Phaseolus vulgaris L.) breeding program aims to obtain high yielding lines with quality bean seeds, disease resistance, and upright plant growth habit. The aims of this study were to evaluate the resistance of 527 common bean lines to the principal physiological races of Colletotrichum lindemuthianum and the Fusarium oxysporum f. phaseoli; to estimate genetic parameters and verify the efficiency of the genealogical and bulk methods in conducting these lines. Of these 527 lines, 279 were conducted by the genealogical method and 248 by the bulk method. For the field experiment, the Federer augmented block experimental design was used. Two commercial cultivars carioca seed coat were used as controls for the lines the same color, and more two commercial cultivars for the black seed coat lines. The traits evaluated in the field were plant height (PH), plant growth habit (P), bean seed yield (BY), sieve yield (SY), and lightness of the bean seed coat (L). Of the 527 lines evaluated for anthracnose, 207 were resistant, 57 moderately resistant, and 263 susceptible. For fusarium wilt, 58 were resistant, 53 moderately resistant, and 96 susceptible. For the carioca seed coat lines obtained by the genealogical method, the heritability (h²) estimates stood out for P, BY, L at 40 d, and gain from selection for BY. The h² stood out for black seed coat lines in the PH and SY traits, it can be concluded that the lines obtained by the genealogical method had better performance for all the traits.

“…The selection gain was highest in the bulk method (4.45%), followed by SSD (2.97%), and bulk within F 2 (1.86%) methods (Table 3). Silva et al (2013) obtained higher genetic gains, but with the same ratio among methods. These authors worked with the same population, and evaluated the fiber content using a higher number of F 7 progenies, which were only tested at two locations.…”

ABSTRACT. Grain yield is strongly influenced by the environment, has polygenic and complex inheritance, and is a key trait in the selection and recommendation of cultivars. Breeding programs should efficiently explore the genetic variability resulting from crosses by selecting the most appropriate method for breeding in segregating populations. The goal of this study was to evaluate and compare the genetic potential of common bean progenies of carioca grain for grain yield, obtained by different breeding methods and evaluated in different environments. Progenies originating from crosses between lines and CNFC 7812 and CNFC 7829 were replanted up to the F 7 generation using three breeding methods in segregating populations: population (bulk), bulk within F 2 progenies, and single-seed descent (SSD). Fifteen F 8 progenies per method, two controls (BRS Estilo and Perola), and the parents were evaluated in a 7 x 7 simple lattice design, with plots of two 4-m rows. The tests were conducted in 10 environments in four States of Brazil and in three growing seasons in 2009 and 2010. Genetic parameters including genetic variance, heritability, variance of interaction, and expected selection gain were estimated. Genetic variability among progenies and the effect of progeny-environment interactions were determined for the three methods. The breeding methods differed significantly due to the effects of sampling procedures on the progenies and due to natural selection, which mainly affected the bulk method. The SSD and bulk methods provided populations with better estimates of genetic parameters and more stable progenies that were less affected by interaction with the environment.

“…There are some research results, such as those by Londero et al (2006) and Silva et al (2013) that provide evidence that fiber content in common beans is influenced by the environment. In this sense, it is of paramount importance to determine the magnitude of the genotype by environment interaction in the estimates of the genetic parameters related to crude fiber content so that the selection of superior lines can be more efficient.…”

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.
