Abstract
A comparative evaluation of 16 sorghum varieties has been attempted to identify suitable pairs of parents. Studies on combining ability indicated considerable variability for gene action in different sets of parents. A substantial portion of the total genetic variance was of the additive type for plant height, earhead length and grain yield. The magnitude of non-additive genetic variance in respect of the characters days to bloom and poduncle length was high. Parents with high combining ability have been identified.
