To evaluate the grain yield stability of rapeseed promising lines in different environmental conditions, thirteen spring oilseed rape genotypes were assessed in a randomized complete block design with three replications in four locations (Karaj, Sari, Gorgan and Zabol) during two years (2015-2017). Simple analysis of variance showed that there was a significant difference between rapeseed lines in terms of grain yield at a probability level of 1%, which indicates that there is enough genetic diversity between them. In combined analysis of variance, the effects of year, location, year × location and genotype × location were also significant at 1% probability level. The comparison of mean grain yield showed that the rapeseed lines Simba, L104 and RGS003 produced the highest grain yield of 3105, 3058, 3032 kg ha-1, respectively. For stability analysis, different methods of stability including one-variable and regression methods (12 methods in total) were performed. Based on the integration of the results of these methods, three rapeseed lines Simba, L104 and RGS003 were stable and high yielding. For complementary studies, it will be recommended that these stable and high-yielding rapeseed lines be used in farm trials in target areas under farmer's conditions.
