The cotton involves a large quantity of useful variability. The experiments have been performed during 2000-2001, in Romania, at ARDS Teleorman, Branceni center and had in view the elucida-tion of some aspects regarding the genetic control of the main agronomically useful quantitative genetic traits in cotton. Ten parental genotypes in C7 inbreeding generation and 45 direct hybrids obtained by n (n-1) diallel crossing in F1 generation were tested. The results led to the hypothesis that the genetic control of the main traits in cotton is of type: total dominance for the insertion height of the first sympodium expressed in nodes; partial dominance for the distance between cotyledonal node and insertion one of the first sympodium (cm) and for the fiber length; overdominance for the weight of early yield from the total one, early yield, capsule weight, fiber content and total yield. The tested traits have large heritability excepting the capsule weight. The results are strictly available for the utilized genitors.
