Abstract:
Present study comprises of 45 introduced and 2 indigenous genotypes of linseed which were evaluated at Experimental Farm of the Department of Crop Improvement, CSK HPKV, Palampur during rabi 2018-19. The experiment was carried out in RCBD with three replications. Each genotype was evaluated for 10 yield contributing characters. High heritability coupled with high genetic advance was recorded for primary branches, secondary branches, number of capsules, biological yield and seed yield. Seed yield showed highest significant positive correlation with biological yield (0.847) followed by plant height, primary branches and secondary branches. Significant negative correlation was observed for days to 50 per cent flowering and days to 75 per cent maturity. The results of path analysis revealed highest direct effect of biological yield (1.088) and harvest index (0.554) with seed yield, while primary branches, secondary branches and number of capsules showed higher indirect effects via biological yield.
