Abstract

                                Combining ability analysis in a 13 x 13 diallel cross involving nine tall and four dwarf cotton genotypes revealed that additive genetic variance played an important role in controlling yield and quality. Four tall parents, PH-93, NH-210, suman and LRA-5166 were good general combiners for seed cotton yield, boll number, boll size and seed index. Among the dwarf genotypes, NH-262(a) and 081 were good general combiners for halo length and ginning out turn respectively. Six crosses involving tall x dwarf parents, four of tall x tall and one of dwarf x dwarf had high sea effects worthy of further exploitation.
