Zinc (Zn) deficiency is widespread in wheat grown on alkaline calcareous soils. A large population of the world as result of this also lacks adequate Zn nutrition. A pot study was conducted on Pindorian series (Udic Haplustalf) to evaluate the distribution of Zn in grain and straw of 12 indigenous wheat genotypes. Zinc was applied @ 6mg Zn per kg soil as ZnSO4.7H2O. Various fertilizer doses were imposed in triplicate according to complete randomized design. All 72 pots received uniform dose of 60 mg N kg-1 soil as urea, 60 mg P per kg as monoammonium phosphate and 30 mg K per kg soil as K2SO4. Plant tops were harvested 30 days after sowing. There was a significant (P less than 0.05) main and interactive effect of wheat genotypes and zinc application on grain and straw yield, Zn concentration and total uptake of Zn by wheat plants. Sehar-06 produced maximum grain and straw yield whereas Iqbal-2000 produced minimum grain and straw yield. The genotypes Sehar-06, Shafaq-06 and S
