Abstract
The line x tester analysis for combining ability of three lines and 17 testers of cotton (G. hirsutum) indicated predominance of nonadditive genetic variance for seed cotton yield and fibre length. The female parent, G. Cot. 14, though a good general combiner for seed cotton yield was a poor general combiner for fibre length. G-67 was an average general combiner and G. Cot. 10 a poor general combiner for both the traits. Out of the 17 males, PKV-072 Trianhpy-3, 0–356 and DP-90 had good combining ability for both characters. The crosses with high sca effects did not always involve high gca parents.
