Improved varieties play an important role in increment of production. This study was conducted for selection of bread wheat lines with high yield , agronomically appropriate traits and wide adaptation using 132 genotypes in a systematic design at 5 locations in cold regions (Karadj, Hamedan, Mashhad, Ardebil and Miandoab) in 2009/10 cropping season. Comparison of the genotypes and their adaptability were carried out using non-parametric statistic method of ranking. Based on present results 48 genotypes which were better than or were at the level of the check cultivars, were selected as the superior genotypes for further evaluation in advanced yield trial (ARWYT-C89) in 2010/11 cropping season. The range of grain yield of the selected genotypes was between 6572 and 9246 kg ha-1, and their average was 7643 kg ha-1 with standard deviation of 572 kg ha-1. Means grain yield of the check cultivars i.e. Shahryar, Zarrin, Alvand, Gaspard and Gascogne were 6424, 6323,5909,6142 and 6886 kg ha-1 , respectively and their grand mean was 6337 kg ha-1.
