The study was conducted to find out the inheritance pattern and genetic parameters for different attributes in a diallel cross involving five genotypes / lines of Pearl millet. Analysis of variance showed highly significant differences among genotypes for all the characters under study. Haymans (1954) method was used to determine the genetic component of variation and type of gene action controlling the particular trait. The results revealed that non additive genetic effects were more pronounced in the inheritance of plant height, number of tillers per plant and number of nodes per plant. While days to 50% flowering showed additive type of gene action. Asymmetrical gene distribution was present for plant height, number of tillers per plant and number of nodes per plant whereas parents contained the same number of genes for days to 50% flowering character. Lack of directional dominance was observed in all the traits except plant height. The graphic analysis showed that plant height, tillers per plant and nodes per plant were under the control of over dominance which can be easily exploited by heterotic effect. Additive type of inheritance was noticed for days to flowering character.
