The gene effects for ten quantitative characters were studied in five hybrids of forage sorghum grown in two environments created in kharif, 1974. Among all the variance components, additive, dominance and both types of non-allelic interaction variance were found to play a significant role in the expresion of these characters. Green and dry matter yield/plant, and the major yield contributing characters like the number of leaves/plant, leaf length, leaf breadth and weight were found to be governed mainly by the dominance component as well as by the epistatic interactions. On the contrary, additive gene action was found to be predominant for days to flower, plant height and stem thickness
