An experiment was conducted to find out the variation in tolerance toward Zn deficiency among four different wheat genotypes using chelate-buffered nutrient solution of three Zn activities. The genotypes 2+ (NRL-1027, NRL-1241, NRL-1242 and NRL-1243) were transplanted to nutrient culture solution in a net house for 45 days to find the impression of various levels of Zn activity (2, 10 and 40 pecomolar (pM) ) on shoot and 2+ root biomass. Among all the wheat genotypes,“NRL-1242” exhibited the highest tolerance to Zn deficiency and hence categorized as Zn-efficient, whereas “NRL-1243” proved to be Zn-inefficient. The remaining two genotypes were medium in efficiency on the above criteria. Efficient wheat genotype “NRL-1242” showed less reduction in growth and accumulated higher P at all lower Zn activities. Thus on the basis of survival in low Zn availability genotypes “NRL-1242”may be used by the researchers to plan their breeding experiments and to set genotype specific recommendations to Zn deficient soils.
