Abstract

A study was taken up to assess the extent of heterosis for yield components in a 4 x 4 diallel. Substantial heterosis was noticed for all the characters studied except 100- grain weight. The hybrid Co 41 x IR 50 was identified to be superior by recording maximum heterosis for grain yield besides heterosis for four other characters namely, plant height, ear bearing tillers, ear length and grain number.
