ABSTRACT

Genetic architecture of slow-rusting resistance to leaf rust was studied using
generation mean analysis involving six basic generations (P1,P2, F1, F2, BC1 and
BC2) of two bread wheat crosses viz., J 24 x HD 2189 and J 24 x HS 347. The
individual and joint scaling tests revealed the presence of digenic epistasis for
inheritance of slow-leaf rusting in both the crosses. The best fitting model revealed
the significance of only additive (d) gene effect in cross J 24 x HD 2189 where
simple selection could be effective for exploiting slow rusting phenomenon. In case
of cross J 24 x HS 347, all the gene effects except (m) were significant indicating
importance of additive and non-additive gene effects. Therefore, improvement
through reciprocal recurrent selection, biparental mating or diallel selective mating
could be employed for improvement of this trait. However, number of gene pairs
controlling slow-leaf rusting was quite variable in both the crosses.
