Abstract: An experiment was conducted during 2017-18 at Experimental Research farm BAU, Ranchi, to estimate the heterosis and inbreeding depression in six crosses of linseed for different characters. Significant heterosis over better parent was observed for days to 50% flowering, technical height, plant height, seed yield per plant, 1000-seed weight and oil content. The heterosis over economic parent-I (Parvati) showed significant desirable for days to 50% flowering, days to maturity, technical height, plant height, number of capsules per plant, number of seeds per capsule, seed yield per plant, 1000-seed weight and oil content in different crosses. Heterosis over check variety-2 (T-397) was observed significant and in desirable direction for number of capsules per plant, capsule diameter, seed yield per plant and 1000- seed weight and oil content in various crosses. Significant and desirable inbreeding depression was seen for days to 50% flowering, days to maturity, technical height, plant height, number of seeds per capsule, and oil content in different crosses.
