Abstract
Wheat (Triticum spp.) is self pollinated cereal crop, belonging to the
family Poaceae (grasses) and is the most important and universally grown of
all food grains having its origin in south western Asia. It is estimated that one
third of the world’s population depend on wheat for their nutritional
requirements. Abiotic stress is the primary reason for farm production loss
worldwide, causing average yield reductions of more than 50%, in wheat
(Triticum aestivum). The present investigation was carried out with an aim to
study the candidate genes responsible for resistance against heat and drought
in wheat and comparison of gene expression between control and stress
tissues with in susceptible and resistant genotypes through RT-PCR.
Genotypes differing in degree of sensitivity to drought, heat, combine
heat and drought stress selected were GW11 and GW273. The study was
conducted with objectives for screening of Hsps genes under heat, drought
and combine heat & drought stress and also to study the differential
