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 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; harvest index, length of panicle, total above ground dry matter and grain yield per plant, in which duplicate epistasis was involved in the expression of all these traits and parent SPV1587 was found superior in contributing traits harvest index, length of panicle and total above ground dry matter while parent Phule Maulee was found superior in contributing grain yield per plant in cross SPV-1587 x Phule Maulee.
