ANALYSIS OF HARVEST INDEX INTHREE CULTIVATED SPECIES OF BRASSICA
Main Article Content
Abstract
Low genotypic coefficient of variation for harvest index (HI) but high for grain yield and biological yield was observed in Fl population of toria. Low GCV was observed for this attribute in the elite stocks of Brassica campestris and Brassica jllncea but it was high in BNssica nlg054. It wu positively associated with grain yield. Seed yield was the major contributor to variation for harvest index in three Brassica species. Additive gene action wupreponderantforHIbut nonadditive for seedand biologicalyield.Theparentspr16-3, pr16-5 and pr16-1 were good general combiners. The highest BP heterosis (61.23%) for harvest index was observed in the hybrid pr16-2 x pr 16-6.
