Abstract
Six ecogeopraphically and genetically diverse lines uf pearl millet, reprsenting world germplasm were crossed in all possible combinations, including reciprocals and parents. Inheritance of days to 50 per cent heading, tiller number, head ength and head thickness was studied by using the technique of geometric analysis in a diadel cross Over-dominance was observed for days to 50 per cent heading but for all other characters partial dominance was operative. Complementary epistasis was observed for days to 50 per cent heading, tiller number and head thickness and the degree of dominance observed may not be due only to a dominance relationship of alleles at the same locus. Mostly the parents had large number of dominant genes for different characters but the dominant genes in one differed from those of the other. This accounted for the magnitude of complementary epistasis observed. It could be concluded from this study that additive gene effects played important role in the inheritance of all the characters; for tillering and head thickness complementary epistasis was also operative; and for heading date dominance was operative in addition to additivity and epistasis.
