Abstract
Five diverse fababean (Vicia faba L.) genotypes were crossed in half diallel method. The F1 seeds along with their parental genotypes were sown in a randomized complete block design with three replications during 2019 /20 season at Sakha Agricultural Research Station. Analysis of variances revealed highly significant effects of genotypes for all the studied traits, providing evidence for the presence of large amount of genetic variability. The parental genotypes; Santamora and Sakha 3 were considered as good sources forresistance to chocolate spot and rust and high yield ability. Meanwhile, the parental genotypes; Giza 429 and R.V323 considered as good sources for early flowering. Due to the significance of gca and sca variances, the additive as well as non-additive components were more important for all the studied traits under study. The estimates of GCA/SCA mean squares were more than unity for all traits, except No. of branches, pods, seeds and crude protein content, where the same ratio was less than unity. This indicated that most of the genetic variation in these traits appear to be additive. Heterotic effects over mid and better parents were detected in the crosses. Based on the two estimates of heterotic effects, the following crosses: C1 (Giza40 x Santamora), C8 (Giza429 x Sakha3), C9 (Giza429 x R.V) and C10 (Sakha3 x R.V) exhibited significant positive heterotic effects over both mid and better parents for most studied yield characters. Progenies of these crosses will be used in bulk method selection program to produce high yield potentiality pure lines.
