EVALUATION OF YIELD AND SOME MORPHOLOGICAL TRAITS OF WHEAT VARIETIES UNDER DROUGHT STRESS

Since the drought is known as one of the most essential factor limiting growth and crop production, an experiment was carried out to evaluate the yield components of 15 bread wheat genotypes in a randomized complete block design with three replications in Islamic Azad University Research Farm of Ardabil in 2011-12. In this study, traits such as yield per ha, plant height, spike length, number of grains per spike and seed weight were studied....
