General and specific combining ability in dual purpose sorghum [Sorghum bicolor (L.) Moench]

Abstract

The aim of this study was to evaluate the general combining ability of sorghum lines and the specific combining ability of the hybrids for yield and its related traits. Three fertility restorer lines, ten malesterile lines, and their hybrids from line x tester mating design crosses were evaluated in RBD with three replications in four environments. Analysis was performed using the Griffing's method of diallel ( 1956) for individual environments and Daljit Singh (1979) for over the environments. There was a significant effect of GCA and SCA for most of the traits evaluated, indicating the participation of additive or dominant genes in inheritance.
