In order to study yield, yield components and some other traits in new wheat genotypes under irrigated conditions in Ardabil and to select the best high yield genotype, an experiment was conducted in three replications in a completely randomized block design at the Ardebil Agricultural and Natural Resources Research Station was planted during the 2017-2018crop year. The results showed that all traits showed significant differences among cultivars and genotypes. Except for the 1000-grain weight trait that was significant at the 5% probability level for the other studied traits, including yield and yield components, plant height, spike emergence, harvest index, biomass, etc, inone percent were significant. The highest grain yield was observed among cultivars and genotypes in genotype 4, while this genotype was statistically similar to genotypes 5, 6 and 7 while the difference in genotype yield was observed. However, the yield difference between of genotype 4 or genotype 2 (lowest yield) was about 50%. Genotype 4 has high seed weight, spike number and high yield compared to other cultivars and is suitable for cultivation in the region.
