In order to Study and preliminary yield comparison of oilseed rape lines, 21 lines along with two foreign cultivars and Okapi as check cultivar were evaluated in Karaj, Isfahan, Hamadan, Islamabad, Arak, Khoy and Bojnoord in 2010-2012 cropping seasons using randomized complete block design with three replications. During the farming season all agronomic traits such as days to start flowering, end of flowering, plant height, number of seeds per pod, number of pods on main stem, number of branches, total pods per plant, maturity were recorded. Based on the results of the seven sites of experiment i.e. Karaj, Isfahan, Hamadan, Islamabad, Arak, Khoy, and Bojnoord, Lines number L109, Hybrid cultivar NK OKTANS, L64, L73, L63, R15 and L137 with 4224, 4208, 4100, 3934, 3870, 3869 and 3810 kg/ha seed yield respectively were superior than check variety Okapi which ranked 22 with 3502 kg/ha seed yield. Selected lines with high yield and suitable traits will be evaluated in advanced yield triales in cold and mild cold regions in two years
