Abstract

Three lines and twenty two testers were crossed in line × tester fashion and the resultant 66 hybrids were evaluated along with the check for days to 50% flowering, days to maturity and grain yield per plant for combining ability analysis. The general combining ability study revealed that among the lines, the line AKRMS-47 A and among the testers, the tester RL5-1, Rb-397-2, AKSV 70 R and G-45-3-1-1 were found to be the good general combiners for grain yield along with earliness. This one line and four testers need to be extensively used in crossing programme for development of high yielding and early maturing rabi sorghum hybrids.
