Generation mean analysis with six generations, a set of 60 treatments (10P1, 10P2, 10 F1, 10 F2, 10 BC1 and 10 BC2) was chosen to study the nature and magnitude of gene effects for seed yield and yield attributing traits. The studies were undertaken on Randomized Block Design with three replications in Rabi 2015-16. The range of heterosis over better parent was observed from to per cent. | Heterosis and inbreeding depression for seed yield and its related morphological traits in linseed (Linum usitatisimum L.)
