“…Our genetic progress related to SY was similar under low (0.48%, 95% HPD = 0.31; 0.64%) and high N (0.53%, 95% HPD = 0.39; 0.65%), indicating that modern cultivars do not demand more N fertilization to be more productive than cultivars released earlier. Around ten years are needed to develop a new common bean cultivar (Moreira et al, 2010). As the number of selected lines is reduced, the range of environments in which they are tested is wider.…”

“…Many methods (bulk, bulk within F 2 , pedigree, and single-seed descent (SSD) have been simplified and optimized for use to reduce the costs of cultivar development in the breeding of these species (Vales et al, 2009). Breeding methods used to develop some common bean cultivars in public institution programs were assessed by Moreira et al (2010), who reported good performance of the pedigree, bulk and single-pod descent methods. The bulk within F 2 and F 3 methods are also often used in common bean breeding programs in Brazil (Ramalho et al, 2012).…”

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.
