“…Breeding strategies depend on the type of cultivar intended for commercial use. Although sweet sorghum is an autogamous plant, breeding programs have been conducted to obtain hybrids using the milo-kafir genetic-cytoplasmic male sterility system (Reddy et al 2005, Bunphan et al 2013. Adoption of this strategy is more justifiable if there is evidence of non-additive gene action in genetic control of the traits of interest, which can be investigated through the use of suitable genetic cross-breeding, such as diallel crosses.…”

In breeding of sweet sorghum hybrids, non-additive genetic effects are important in phenotypic expression of the traits of interest. The aim of this study was to evaluate the general combining ability (GCA) of sweet sorghum lines and the specific combining ability (SCA) of the hybrids for agronomic and technological traits. Five fertility restorer lines, four male-sterile lines, and their hybrids from partial diallel crosses were evaluated in experiments laid out in a 5 x 6 triple rectangular lattice design in the municipalities of Lavras, MG and Sete Lagoas, MG, Brazil. Diallel analysis was performed using the Griffing model adapted to partial diallel crosses. 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. The restorer lines CMSX508, BRS 511, CMSXS643, and CMSXS646 show potential for use as parents in sorghum breeding programs.
