Abstract

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. Analysis of variance indicated a significant difference among genotypes for all traits were evaluated. The overall mean yield in genotypes was 2427.1 kg ha in this study. Genotype 12 with 3125 kg ha produced the higher grain yield and genotype 9 had the lowest (1650 kg ha) than other genotypes.
