Yield of six dryland durum and eleven dryland bread wheat lines was evaluated in a randomized complete block design with three replications in Tark and Alengareg vilages of Kandowan region of Miyaneh in 2007. In harvest stage, some traits such as yield, plant height, ripening time, tolerance to dry and cold conditions, thousand seed weight, and tiller numbers were recorded. There was significant difference between durum genotypes in plant height and thousand seed weight at both studied regions. Also, genotypes were significantly different in dry tolerance and fertile tiller numbers, but not regions. Interaction of region in genotype was significant in yield, tiller numbers and dry tolerance but in plant height and thousand seed weight. Among durum lines, Gardish was the highest one. The highest yield belonged to PI40100 with significant difference with the rest of the lines. Dry tolerance in Haurani and tiller number in Haurani, G-1252, Dipper and PI40100 was in the highest level, significantly. Plant height was also significantly different among beard wheat genotypes in both regions. Regions and genotypes were significantly different in yield and thousand seed weight. Among bread wheat lines, plant hight in Sardari was significantly higher than others. As a whole, thousand seed weight and yield in Unknown-11 was significantly higher than other bread wheat genotypes.
