Abstract:
The present investigation was undertaken to estimate additive and dominance components including epistasis by three parameter model (joint scaling test) and gene action and genetic components by six parameter model for some quantitative and qualitative traits in linseed. The estimates of additive and dominance components through joint scaling test as well as epistasis interaction through six parameter model indicated that additive component has significant role in the expression of number of primary branches per plant, number of seeds per capsule, capsule diameter and test weight indicating that transgressive segregants of these characters can be useful for improvement of these traits in segregating generations. Dominance component played a major role in controlling the expression of number of primary branches per plant, number of seeds per capsule, seed yield per plant, test weight and rust disease reaction. Among epistatic gene interactions, additive x additive (i) and dominance x dominance (l) interactions effect showed significant impact in comparison to additive x dominance (j) interaction in controlling the expression of plant height, number of primary branches per plant, number of capsules per plant, number of seeds per capsule, capsule diameter, days to maturity, seed yield per plant, oil content, wilt disease reaction and rust disease reaction by additive x additive (i) interaction, days to 50 per cent flowering, plant height, number of capsules per plant and number of seeds per capsule by dominance x dominance (l) interaction and days to 50 per cent flowering, plant height, number of capsules per plant, days to maturity, oil content, wilt disease reaction and rust disease reaction by additive x dominance (j) interaction.
