Abstract
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.
