Abstract

                                In 10 x 10 diallel analysis in linseed, additive (D) and dominance (HI and H2) components were found significant for days to flower, days to maturity, plant height, capsules per plant, 500-seeds weight, harvest index and seed oil content. Only dominance components (H) and H2) were significant for number of seeds per capsule and biological yield. The degree of dominance indicated preponderance of additive genetic variance for days to flower and days to maturity, equal importance of both genetic components for 500-seeds weight and seed oil content and greater magnitude of dominance component for rest of the characters. Reciprocal recurrent selection or biparental mating is suggested for improvement of all the characters except seeds per capsule and biological yield.

Key words : Linseeds, genetic analysis, additive and dominance component. diallel analysis, biological yield
