Seven wheat varieties (Sarsabz, Kiran-95, Khirman, NIA-Amber, NIA-Sunhari, NIA-Sunder and NIA-Saarang) were evaluated for their growth response to P deficient (0.02 <em>mM</em>) and adequate (0.20 <em>mM</em>) levels in hydroponic culture. A factorial combination of treatments, repeated four times, was arranged in a completely randomized design. Wheat varieties differed significantly (<em>P</em>< 0.01) in shoot and root dry matter production, root: shoot ratio, shoot and root P concentration and uptake, and shoot P utilization efficiency. Shoot P uptake and utilization efficiency were strongly correlated (r = 0.89, r = 0.77) with shoot dry matter production. On the basis of shoot dry matter production and P utilization efficiency, cultivars were grouped into four categories. NIA-Sunder, Sarsabz and Kiran-95 were efficient as well as responsive (ER) genotypes. Khirman, NIA-Sunhari, NIA-Saarang and NIA-Amber were categorized as non-efficient and non-responsive (NENR) genotypes. Prevalence of such genetic variations among these wheat cultivars can be useful in developing P- efficient genotypes.</p>}, number={2}, journal={Pakistan Journal of Agriculture, Agricultural Engineering and Veterinary Sciences}, author={Abbas, M. and Aslam, M. and Shah, J.
