A line x tester crossing programme was taken up with seven lines and five testers with a view to obtain best heterotic crosses for seed cotton yield along with fiber quality traits. The Crosses viz. ,combinations GSHV-97/13 x AKH-7859, 4384 x AKH-076R, 4384 x AKH-7859, GJHV-156 x AKH-03-8h and GSHV-97/443 x DR-8 showed highly significant and positive standard heterosis for seed cotton yield per plant. Twenty six and twenty nine hybrids showed significant and positive standard heterosis for span length and fiber strength. Nine hybrids for ginning percent, three hybrids for strength: length ratio and one hybrid GSCMS-10 x DR-16 for LUR exhibited significant and positive standard heterosis.
