Heterosis Studies in Yellow Sarson (Brassica campestris var. yellow sarson)

摘要

Fourty crosses of yellow sarson (Brassica campestris var. yellow sarson) alongwith their parents were evaluated for heterosis during rabi 2006-07, using L x T fashion. Heterosis over better parent and standard check were estimated for seed yield and other eight yield components. Based on mean performance, the cross NDYS-9503 x NDYS-2 showed highest seed yield and exhibited high heterosis (120.78%) and high standard heterosis over NDYS-2. The important yield components such as plant height, primary branches per plant, siliquae per plant, delayed days to 50% flowering and test weight would be more desirable to exploit heterosis in yellow sarson.
