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

Published on

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 (F
2) 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 F
2 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.
