In order to evaluate and compare of stability and yield of 20 superior winter rapessed lines (Brassica napus L.) and 3 promising line along with Okapi and Modena as check, two field experiments was carried out during 2009 – 2011 growing seasons based on randomized complete block design with three replications in research station of Agricultural and Natural Resources Research Center of Markazi Province, Arak, Iran. Each plot was incloding of four rows with 5 meter length and 30 centimeter distance. Important agronomic traits such as days number to initiation and end of flowering, length of flowering, days number to ripening, length of ripening, plant height, second branche number per plant, seed number per pod, pod number per plant were recorded during growth season. After harvesting, 1000 - seed weight and yield was estimated. The results of compuned analysis of variances showed that rapeseed cultivars had significant differences for all measured traits at 1% level prpbability.In this research, SW102 line had the most grain yield (4890 kg/ha) and L147 line showed the least grain yield (2732 kg/ha). Inaddition, grain yield of Okapi and Modena cultinars was equal 3622 and 3928 kg/ha, respectively. Keywords: Line, Winter Rapeseed, cold and semi cold location
