Abstract:
Seven sesame (Sesamum indicum L.) genotypes were crossed in a half diallel mating fashion. The analysis of variance revealed that the parents and their hybrids under study possessed sufficiently high amount of genetic variability. The component D measures the additive effects of genes. Greater values of H1 than H2 and the ratio of H2 /4H1 (< 0.25) confirmed the unbalanced distribution of gene at the loci in the parents implying dominance for all the traits. It was also confirmed by greater than one value of KD/KR components for all the traits which suggested the higher frequency of dominant genes than recessive genes in the parents. The component F was indicating the presence of an excess of dominant alleles than recessive alleles. In graphical analysis, the regression line intercepted Wr axis below the origin indicating over dominance for all the traits except plant height.
