Abstract

The micronutrient malnutrition is being increasingly extended due to rapid growth of human population beside the expansion of agronomy systems. One approach of resolving this problem is employing cultivars with high absorption efficiency for these elements. This Study was designed to evaluate the effect of zinc foliar application and its accumulation in wheat grain on agronomic traits and iron accumulation in the grain of facultative and winter wheat varieties that were conducted in two separate experiments based on RCB design with three replications. The results explained a significant positive effect of zinc foliar application on all traits except grain iron content. The growth type had significant effect on all traits. The effect of variety within the growth type was significant in terms of all traits and indicated high genetic variation among the varieties. Back Cross Roshan, Shahpasand and Mihan were the best varieties in term of grain yield. Bisotoun, Kaveh, Tous and Mahdavi vari

Grain Iron Content, Grain Zinc Content, Wheat.

Conclusion

Based on the positive correlation between grain yield and its iron content and their negative correlation with grain's zinc content, it seems that combined selection method is impossible for these three traits in the studied cultivars, so in order to produce high- performance cultivars with considerable zinc and iron grain contents, it is recommended to consider combination between far cases in terms of grain's zinc content followed by selection between the obtained results.
