The experimental material comprised of six basic generations, viz., P1, P2, F1, F2, BC1 and BC2 of four pearl millet crosses (ICMB 95222 × J 2372, ICMB 95444 × J 2340, ICMB 94555 × J 2290 and JSMB- 101 × J 2405). The individual and joint scaling tests indicated the presence of epistasis for all the characters studied, except for number of productive tillers per plant and fodder yield per plant. The nature and magnitude of gene effects indicated, that the nature and magnitude of gene action varied from cross to cross. Hence, each cross has to be handled separately for specific character. The results also indicated the role of either higher order gene interaction or tight linkage for the expression of grain yield per plant, 1000 grain weight and days to maturity.
