Abstract:
The field experiments were conducted in Randomized complete block design with three replications during rabi season 2019-20 in twenty-seven IGKV released linseed genotypes including three checks (RLC-92, RLC-133 and RLC-143). Analysis of variance for all the traits showed the existence of sufficient amount of variability present among twenty-seven linseed genotypes. The maximum genotypic coefficient of variation and phenotypic coefficient of variation was found to be the highest in number of secondary branches per plant followed by number of capsules per plant, number of primary branches per plant, harvest index (%) and seed yield per hectare (qt.) implying the existence of appreciable amount of variability for those traits among the genotypes. Number of secondary branches per plant recorded high broad sense heritability coupled with high genetic advance as percent of mean followed by number of capsules per plant, harvest index (%), seed yield per hectare (qt.), number of primary branches per plant, 1000 seed weight (g), plant height (cm), seed size (mm) and oil content (%). Highest significantly positive correlation was observed for harvest index (%) and number of capsules per plant” subsequently, positive correlation with number of primary branches per plant, days to 50% flowering and oil content (%) at both genotypic and phenotypic level. Presence of Positive association among the desirable characters is favorable because it encourages simultaneous improvement in both the characters. Hence, these characters can be considered as yield determinants.
