In order to evaluate and compare of yield in 28 new winter rapessed (Brassica napus L.) cultivars along with Okapi as check, a field experiment was carried out 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 6 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, seed oil content (%), seed and oil yield was estimated. The results of varians analysis showed that rapeseed cultivars had significant differences for the seed weight at 1% level prpbability. ES Betty had the most giain yield (4035 kg/ha) and Ella cultivars showed the least respectively in comparison with check.Grain yield of Iranian cultivar named seed yield (2050 kg/ha).
