Genetic analysis for yield and ginning out turn in F1 and F2 populations of upland cotton

Abstract

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 specific 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 filial generations. The individual plants with desired traits should be selected in later generations.
