Different crop species and varieties differ genetically in responding to root medium P. We evaluated seven
commonly grown wheat genotypes for their response to P deficiency stress in hydroponics. Wheat genotypes
differed significantly (p<0.001) in their biomass accumulation, root: shoot ratio, P concentration, total P uptake in
shoot and P utilization efficiency. Total P uptake and P utilization efficiency correlated significantly (p<0.001) with
their shoot dry matter yield, root dry matter yield and total biomass production. Chenab 2000 and Dirk proved to
be efficient and responsive genotypes to P application.
Key words: wheat, genotypic variability, phosphorus utilization
