In present study two released and popular hybrids viz. Phule-388 and NHH-44 were evaluated along with their six generations through generation mean analysis to study gene action present for yield and fibre quality traits. The six parameter model was employed for those characters where either of three scales (A, B & C) found significant. Inheritance of the characters like seed cotton yield, lint yield, seed weight per plant, bolls per plant, boll weight, sympodia per plant, monopodia per plant, 100 seed weight and short fibre percent in both crosses; plant height in Phule-388 and 2.5% span length, fibre strength, ginning percent and oil content in NHH-44 was under the control of simple gene effect as well as higher order inter-allelic interactions. Fibre elongation percent in both the crosses and seeds per boll in NHH-44 were solely under the control of dominance gene effect. For oil content in Phule-388 whereas for uniformity ratio, micronaire and plant height in NHH-44 preponderance of the additive effect and additive x additive inter-allelic interaction was evident. In Phule-388, predominance of higher order epistatic interactions was observed for uniformity ratio, micronaire, 2.5% span length, fibre strength as well as for seeds per boll and ginning percent.
