Abstract:A complete diallel analysis that involved 2 indigenous and 2 exotic genotypes was conducted to study the inheritance of lint yield, ginning outturn %, staple length and fibre fineness. Differences among the genotypes were found to be significant (P<0.01) for all the characters. The Wr/Vr graphs revealed that the characters such as lint yield, staple length and fibre fineness were governed by additive type of gene action. Among the varieties Chandi-95 and 8631-20 possessed most of the dominant genes. High narrow sense heritability further revealed that selection could be very effective to improve the traits via selecting segregating generations.
