“…A further modification introduces selection against inferior genotypes during single pod descent. Single pod descent with selection, in this case for maturity, was found desirable since it reduced the size of the population advanced and produced superior lines (Destro et al 2003). In a similar study pedigree selection, single seed descent, and single seed descent with selection for early maturity were compared, and single seed descent with selection was found to be the most costeffective (Byron and Orf 1991).…”

“…Different selection methods used for the identification of desirable traits are the pedigree, single-seed descent, mass selection, and bulk methods (Allard, 2014). In addition, modified selection methods have also been developed and applied elsewhere (Toledo et al, 1994;Destro et al, 2003;Miladinovic et al, 2011). Progress in plant breeding largely depends on the skill of the breeder in identifying selection criteria and applying selection methods that are able to promote the desired changes in characteristics of interest in a breeding program.…”

This study aimed to compare the genetic gains of two different selection methods for agronomic traits in soybean. A population from the cross of VI045032 x 4904 (LSB10) was advanced using the bulk method and modified bulk method to the F6 generation. Measured traits were growth duration, plant height, height of the first pod node, number of pods per plant, the percentage of 3-seeded pods, 100-seed weight, individual yield, and yield. Both methods were equally efficient and could be used for segregating and the stabilizing phase of progenies/populations of soybean crosses. However, the bulk method appeared to be more efficient for the improvement of yield-related traits while the modified bulk method was more efficient for the improvement of morphological traits.

“…The methods used for selection of grain yield in segregating populations have been compared in various crops such as soybean (Destro et al, 2003;Miladinović et al, 2011;Funada et al, 2013), common bean (Raposo et al, 2000;Costa et al, 2002), cowpea (Mehta and Zaveri, 2000), chickpea (Meena and Kumar, 2012), barley (Lalić et al, 2003), sesame (Vinayan and Govindarasu, 2010), cauliflower (Chigeza et al, 2013), and rice (Fahim et al, 1998;Ntanos and Roupakias, 2001;Kanbar et al, 2011). Most of these studies showed significant differences between the methods used for developing superior progenies or lines.…”

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.
