A diallel cross experiment was conducted on stone-ville-213, HG-6-1-N, fregobract-83 and AG-hirsutum-87 upland cotton cultivars to ascertain the type of gene action for different quantitative traits. The genotypes were highly (P ≥0.01) significant. Plant height and boll weight were controlled by over dominant type of gene action, whereas seed cotton yield per plant was governed by partial dominace type of gene action. The variety stone-ville-213 seemed good general combiner for plant combiner for boll weight. The cross stone-ville-213 x fregobract-83 and stone-ville-213 x HG-6-1-N were the best specific combiner for number of bolls and seed cotton yield per plant respectively.
