Abstract:

The significance of scaling test ‘A’, ‘B’, ‘C’ and ‘D’ indicated the presence of all three types of non-allelic gene interaction effects for physiological traits governed by additive (d) gene effects along with predominant of dominance x dominance (l) non-allelic gene interaction effect was important in the inheritance of traits associated with drought tolerance viz., days to 50 per cent flowering, days to physiological maturity, plant height, 1000 grain weight, harvest index, dry fodder yield per plant and grain yield/plant in which duplicate epistasis was involved in the expression of all these traits and parent RSV 1237 was found superior in contributing all traits viz., days to 50 per cent flowering, days to physiological maturity, plant height, 1000 grain weight, dry fodder yield per plant and grain yield/plant while parent RSV 1703 was found superior in contributing harvest index in cross RSV 1237 x RSV 1703. An investigation on generation mean analysis involving six generations (P1, P2, F1, F2, B1 and B2) of the cross RSV1237 x RSV 1703 in rabi sorghum was carried out for the traits associated with drought resistance under non stress and moisture stress condition.
