Abstract

Six parents in sorghum viz, Co18, 148, Co 23, Co 22, CSV. 3 and As. 3880 were crossed in all possible combinations and the hybrids along with the parents were studied for three economic traits under four different environments consisting two seasons and two manurial levels. For panicle length, number of grains/panicle and grain yield/panicle, heterosis was observed in most of the crosses. Among the parents Co 23 showed high mean expression for number of grains and grain yield. Further the hybrids involving Co 23 as one of the parents revealed high per se performance and heterosis for grain yield.

Keywords: Sorghum, Heterosis, Environments.
