Studies on Gene Effects in a Cross or intervarietal Hirsutum Varieties

Abstract

                                Six generations. P1, P2, F1, F2, B1 and B2 of an inter-varintal cross H, 297 x P.S. 16 were used in estimation of gene effects for seven characters by generation means method. For the character seed cotton yield, additive and dominance gene effects were highly significant while interaction gene effects were non-significant. Dup licate type of epistasis were found for the charactors boll number. fibre length, planing percentage, seed index and lint index while complementry type of epistasis was found for boll weight.
