In order to evaluation adaptability, yield comparision and selected earily maturity cultavars, 14 promising spring rapeseed (Brassica napus) cultivars with Hyola 401 and RGS003 (as cheek varieties) were evaluated in karaj one year, using Randomized Complete Block design with 3 replications. During the growth period the most important traits such as days to flowering, days to complet flowering, days to maturity, plant height, seed yield and yield components were recorded. The cultivars Hyola 401, Hyola 308 , Hyola 420 and Hyola 330 with mean seed yields at 5 location and in two years equal to 4083, 3848, 3831 and 3745 respectively had the best ranking. The OP cultivars Hyola 401, RGS003, Ogh-4, Ogh-14 and Ogh-6 with mean seed yields around the 3604, 3506, 3496, 3462 and 3060 respectively, occupied the 1 to 5 ranks. Also OP varieties were early maturity (2 -3 days) than Hyola 401.
