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 137 lines in a systematic design at 7 locations in cold regions in 2007/08 cropping season. Comparison the lines and their adaptability were carried out using non-parametric statistic method of ranking. Based on present results 32 lines which were better than or were at the level of the check varieties, were selected as the superior lines for further evaluation in advanced yield trial (ARWYT) in 2008/09 cropping season. The range of grain yield of the selected lines was between 5714 and 7266 kg ha-1, and their average was 6259 kg ha-1 with standard deviation of 386 kg ha-1. Means grain yield of the check varieties i.e. Shahryar, Zarrin, Alvand, C-80-4 and C-81-4 were 5915,6201,4915,6302 and 6359 kg ha-1 , respectively and their grand mean was 5938 kg ha-1.
