ABSTRACT
Wheat (Triticum aestivum L.) is the main cereal crop in Pakistan. Wheat is the principal source of
food and is extensively grown, consumed, and preferred in Pakistan. But due to the increased use of
poor-quality water for irrigation and salinization, their growth and yield are decreasing day by day in
Pakistan. Wheat is a salt tolerant cereal crop, and new genotypes of wheat with diverse salt tolerance are
being developed continuously to cope with salinity and improve crop productivity. A pot experiment was
conducted in the Department of Soil and Environmental Sciences, Ghazi University, Dera Ghazi Khan,
to explore the role of salt stress on the morphophysiological response of wheat genotypes. Treatments
were T1: control, T2: 6 dsm-1, T3: 9 dsm-1, and T4:12 dsm-1 in a Factorial Completely Randomized
Design (CRD). The results showed that salt stress reduced the growth parameters of wheat under a
saline condition. Further, the wheat genotype G2 (108) is a more salt tolerant genotype because it gains
the highest shoot fresh weight, plant height, shoot length, number of spikelets, shoot dry weight, root
length, 1000 grain weight chlorophyll contents, membrane stability index, and less shoot Na+, while the genotype G1 (133) is a salt sensitive genotype. Our findings revealed that the genotype (108) is screened
for the future to grow on salt affected soils.
