HETEROSIS IN VARIETAL CROSSES OF SUNFLOWER

Abstract

Twenty cross combinations in sunflower were studied for heterotic potential in seed yield and its important yield components in Sunflower. Seven crosses exhibited significant heterosis over the respective better parents for seed yield capitulum. Among them the maximum degree of herterosis was realised in the combination EC 85820 x BSH 1. The utility of promising hybrids in sunflower breeding has been discussed.
