“…It is necessary to generate enough variability to increase the probability of successful selection in common bean (Fouilloux and Bannerot, 1988;Singh, 1995 andSingh andUrrea, 1995). To achieve this goal it is desirable to use highly divergent parents which are not adapted to the desirable growing conditions.…”

A common bean (Phaseolus vulgaris L.) cultivar must combine desirable genotypes for several traits in order to be accepted by producers and consumers. This study aimed to evaluate selection efficiency when segregating bean populations for traits, by means of a selection index, in order to obtain superior progenies for traits considered. A total of 16 populations from the F 4 and F 5 generations were evaluated in 2011 and 2012, respectively. The traits evaluated were plant architecture, plant disease, grain type and yield. Using standard scores (Z), the sum of the four traits (∑Z) was obtained and, based on this information, the best populations were identified. The evaluation of selection effectiveness was performed on 31 progenies from each population. The 496 progenies plus eight controls were evaluated in the F 5:6 and F 5:7 generations for the same traits in July and November 2012, respectively. The selection, using the index based on the sum of standardized variables (∑Z), was efficient for identifying populations with superior progenies for all the traits considered.

“…The superiority of the bulk-population method over the SSD method and other methods for conducting common bean segregant populations was demonstrated by Fouilloux and Bannerot (1988) and Raposo et al (2000). Comparisons of breeding methods have been performed for other traits besides grain yield, with results always confirming the superiority of the bulk-population method.…”

“…Thus, genotypes present in a population created using the SSD method may not represent an unbiased sample of the original population. Fouilloux and Bannerot (1988), utilizing the SSD method with common beans, ob-served that even under good climatic conditions and normal plant densities, plant losses of 10 to 20% occurred in subsequent generations. If plant loss of 10% were considered for each generation, after four generations, 35% reduction in population size would be expected.…”

“…Losses due to sampling have also been reported for the bulk-population method and are considered a hindrance of the method. Nevertheless, Fouilloux and Bannerot (1988) state that loss of lines does not necessarily lead to a corresponding reduction in genetic variability because the loss of individuals/F 2 lines due to sampling can be compensated by the liberation of variability since F 2 individuals may be highly heterozygous. Muehlbauer et al (1981) demonstrated that in an F 6 generation, 25% of the variability present is due to released variability within the line.…”

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.

“…This is because for every generation from F 2 , one seed per plant is sampled, with no allelic loss among progenies, but with high allelic loss within the progeny. Compared to the bulk method, the sampling of segregating population in the SSD method is less intense, which might indicate reduced genetic variability within the progenies (Martin et al, 1978;Fouilloux and Bannerot, 1988;Mehta and Zaveri, 2000). In contrast, the sampling effect is not restricted to the SSD method, and sampling losses have also been reported as a disadvantage of the bulk method.…”

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.
