“…Krause et al (2012) also found a positive effect of gi for plant height for IAC Carioca Tybatã under field conditions. Gonçalves-Vidigal et al (2008) registered the occurrence of additive and non-additive effects under irrigated conditions for plant height, number of pods per plant, number of seeds per plant, number of seeds per pod, average weight of 50 seeds and grain yield, besides reaching similar results for the cultivar IAC Carioca Tybatã, which showed negative effects of ĝ i for yield and weight of seeds and positive effects of g i for plant height.…”

This paper aimed at selecting parents to compose a common bean breeding program for drought tolerance. General and specific combining abilities were evaluated under controlled conditions, using drought tolerant parents (BAT 477 and SEA 5), elite cultivars developed at IAC (IAC Alvorada and IAC Carioca Tybatã) and their progenies obtained from a complete diallel, including the reciprocals. Sowing was done in soil following a randomized block design with three replications for both experiments, the control with irrigation and the drought stress experiment imposed from pre-flowering stage. Plants remained under drought stress for 30 days. Physiological and morphological traits as well as yield components and grain yield were evaluated, detecting additive and non-additive effects controlling these traits. The parents used in this study had contributed in different proportions in the crosses they participated in. Regarding the drought stress condition in the pre-flowering stage, the parents SEA 5 and IAC Alvorada presented greater positive effects for the general combining ability for the yield and weight of one thousand seeds, whereas the parent SEA 5 also showed a positive effect for the number of seeds per pod, suggesting the increase of these traits in the crosses they participated in. The hybrid combinations SEA 5 × IAC Alvorada showed a positive result for grain yield, related to the higher positive effect for specific combining ability and because they have as parents the cultivars which confer the best positive values for general combining ability.

“…In this case, the superiority of the sum of squares of SCA was observed for GCA (Table 3). Predominance of non-additive effects associated with grain yield and plant height in common bean was also found by Gonçalves-Vidigal et al (2008). Also studying GCA and SCA in segregating F 2 populations derived from a complete diallel, Machado et al (2002) observed predominance of SCA for grain yield.…”

In common bean (Phaseolus vulgaris L.) breeding, plant selection that associate erect plant architecture, high yield, and grains with good commercial acceptance has been the choice of breeders. Thus, this study aimed to evaluate potential parents, to obtain promising segregating populations that associate high yield, erect plant architecture and carioca grain type, as well as to obtain information on heterosis, general and specific combining ability of these parents regarding grain yield and traits related to plant architecture. Fourteen common bean lines were crossed under a partial diallel scheme. Group 1 was composed by eight erect plant lines and group 2 by six carioca grain type lines. The F 1 's plants from the crosses and the 14 parents were evaluated during spring (Mar. sowing) for plant architecture grade, diameter of the hipocotyl, plant mean height, and grain yield. Predominance of additive effects was observed for plant architecture grade and diameter of the hypocotyls. For grain yield and plant mean height, there was a greater contribution of the dominance effects. Thus, selection of erect plants, with a larger diameter of the hypocotyl can be carried out in early generations; while for grain yield and plant mean height, it must be delayed, preferably, to later generations.

“…These results suggest that the heterotic effects detected in F 2 are small. The predominance of dominance effects associated with grain yield in common bean was reported by Rodrigues et al (1998) and Gonçalves-Vidigal et al (2008). However, other studies reported predominantly additive effects for YLD (Santos et al 1985, Kurek et al 2001).…”
