Abstract:
Linseed (Linum usitatissimum L.) is an important rabi oilseed crop which is having diploid chromosome number 2n=30. A wide range of variability was noted for yield and yield components viz., days to 50 per cent flowering, days to maturity, plant height, number of primary branches per plant, number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, biological yield per plant, seed yield per plant, harvest index and 1000 seed weight. High heritability estimates were recorded for four traits (1000 seed weight, days to 50% flowering, number of primary branches per plant and number of capsules per plant) out of eleven studied traits; these could be growing to greater contribution of genetic components in inheritance of these attributes. High estimates of genetic advance as percentage of means were noted for capsules per plant, seed yield per plant, 1000 seed weight, biological yield per plant, number of primary branches per plant and number of secondary branches per plant. Moderate genetic advance as percentage of means were noted for plant height, harvest index and days to 50% flowering. Low genetic advance as percentage of means were noted for seeds per capsule and days to maturity.
