Abstract

Genetic analysis through diallel cross techniques reveal that length of peduncle, density of grain, diameter of peduncle and surface area of primary ear were under the influence of both intra-allelic and inter-allelic interactions. The interaction with regard to the first two characters could be identified as complementary type. Yield of primary ear was found to be conditioned by complementary genes besides some additive factors. Both epistasis and overdominance were found responsible for the observed heterosis in respect of peduncle characters and density of grain. In cases of surface area and yield of primary ear, epistasis alone accounted for the manifest hybrid vigour. In the light of the genetic situations investigated, the characters are discussed for their breeding implication.
