Abstract

A backcross programme was conducted to transfer 13 of
the Lr genes present in the leaf rust differentials being
currently used in India viz., Lr1, Lr2a, Lr2c, Lr3a, Lr9, Lr10,
Lr13, Lr15, Lr17a, Lr18, Lr19, Lr20 and Lr26 in the background
of wheat variety NP 4 having desired agronomic traits.
Homozygous resistant lines carrying these genes singly
have been developed through six backcrosses and
subsequent selection. Nine of these lines have already
been reported. Present communication reports the
remaining four lines carrying the genes Lr13, Lr18, Lr19
and Lr26. These lines being locally adapted and early
maturing are easy to maintain under Indian conditions,
and can be widely used for virulence analysis and genetic
studies.
