Abstract

India is one of the major producers of durum wheat in the world.
Rusts are the important diseases which are considered to be most
important constraints in the global wheat production. Stem rust
caused by Puccinia graminis sf. sp. tritici has been particularly severe on
durum wheat. Even though the durum wheat offers resistance against
certain aggressive and more virulent pathotypes of 40 group like 40A
(62G29) and 40-1 (62G29-1), it is highly susceptible to certain other
pathotypes belonging to 117 group. Wheat stem rust resistance gene
Sr36 (syn. SrTt-1), derived from Triticum timopheevii shows effectiveness
to many stem rust pathotypes including 117-6 (37G19) which is highly
virulent to durum wheat. Presently, Sr36 gene is present in bread wheat
background, whereas, none of the durum wheat genotypes found to
have Sr36 gene. An effort is being made to transfer Sr36 gene into
most popular durum variety HI 8498 by utilizing molecular marker
assisted backcross breeding.
