Promising parents for grain yield and early maturity in rabi sorghum (Sorghum bicolor L. Moench)

Abstract

Four male sterile lines, twelve testers and their 48 crosses were evaluated along with check for days to 50% flowering, Days to physiological maturity and grain yield per plant for combining ability analysis. The general combining ability study revealed that among the lines, the line RMS 2010-10A and among the testers RSV 1941 were found to be the good general combiners for grain yield along with earliness. This one line and one tester need to be extensively used in crossing programme for development of high yielding and early maturity rabi sorghum hybrids.
