ABSTRACT

The experimental material comprised of six basic generations, viz., P1, P2, F1, F2, BC1 and BC2 of
four pearl millet crosses (ICMB 95222 X J 2372, ICMB 95444 X J 2340, ICMB 94555 X J 2290 and
JSMB- 101 X 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.
