Gene action and combining ability for seed cotton yield (SCY) and ginning outturn (GOT) were investigated in F1 and F2 populations
of 4 x 3 line tester in cotton (Gossypium hirsutum L.). The rate of general and specifc combining ability variances showed non-additive
gene action in controlling SCY (F2) and GOT (F1). Carmen cultivar determined as the best general combiner for SCY and GOT. Carmen
x Carisma was the most promising combination to be used as an F2 hybrid and a base population for flial generations. The individual
plants with desired traits should be selected in later generations.
Keywords: GCA, Ginning outturn, Line x tester, SCA, Seed cotton yield.
