Effect of Terminal Drought Stress on Morpho-physiological Traits of Wheat Genotypes (original) (raw)

Development of wheat varieties with low moisture requirements and their ability to withstandmoisture stress may cope-up well with the on-coming peril of drought conditions. Ten wheat genotypesincluding two new strains, PBGST-3, Hero, Bhittai, Marvi, Inqlab, Sarsabz, Abadgar, Kiran, Khirman andPBGST-4 were sown in split plot design with factorial arrangement in four replications at ExperimentalField, Department of Plant Breeding & Genetics, Sindh Agricutlure University, Pakistan during 2012-13.The results revealed that water stress caused significant reductions in all morpho-physiological traits. Thegenotypes differed significantly for all the yield and physiological traits. The interaction of treatments ×genotypes were also significant for all the traits except plant height, productive tillers/plant, grains/spikeand harvest index, were non-significant which indicated that cultivars responded variably over the stress treatments suggesting that breeders can select the promising genoty...
