DETECTION OF EPISTATIC, ADDITIVE AND DOMINANCE VARIATION IN LINSEED (LINUM USITATISSIMUM L.)

Abstract

Three testers, Neelum, LHCK 222 and their hybrid Neelum X LHCK 222, were crossed to ten strains/varieties of linseed to detect the presence of epistatic, additive and dominance variation. Modified triple test-cross analysis was done for nine metric traits. Epistasis did not affect any of these traits.An additive-dominance model was fitted to all the traits. Both additive and dominance gene actions were found significalH. However, additive gene action was predominant than dominance. Partial dominance was observed for all the traits studied.
