Analysis for heterosis in linseed (Linum usitatissimum L.) was carried out for 11 metric traits in linseed using four crosses viz., NDL 2004-05 x GS-234(cross I), NDL 2004-05 x A-95B (cross II), NDL 2004-05 x TL-27(cross III) and NDL 2004-05 x TL-11(cross IV) developed under generation mean analysis. For days to 50% flowering (cross I, II and IV); days to maturity (cross I); plant height (cross I and III); number of primary branches per plant (cross I, II and III); number of capsules per plant (cross II and III); number of seeds per capsule (cross II and III); biological yield (cross II and IV); harvest index (cross II); and seed yield per plant (cross III) had significant or highly significant and positive standard heterosis, heterobeltiosis, mid-parent heterosis and inbreeding depression. Nature and magnitude of heterosis and inbreeding depression varied with crosses, characters as well as environments. Considering the very high degree of heterosis in desirable direction and presence of non-additive genetic variance for yield and yield contributing components; Cross II (NDL-2004-05 x A-95 B) and cross III (NDL-2004-05 x TL-27) were identified better specific cross combination to be used for exploitation of heterosis.
