In order to evaluation and characterization of important agronomical, morphological and botanical traits of new winter rapessed F4 lines (85 Lines) along with Zarfam and parental varieties as check were planted in seed and plant improvement institute's field at Karaj. Due to large number of genetic materials, they divided into 3 separate experiments which each carried out in a randomized complete block design. All important agronomic traits including days to start flowering, days to end of flowering, days to ripening, number of branches, plant height, number of seed per pod, number of pod in main stem, number of pod in plant and seed and oil yield were recorded during growth period. There were great statistical differences between genotypes at all experiments for most of traits revealing desired genetic diversity. Pooled analysis of variance showed that it is possible to use the broad genetic diversity to establish new winter oilseed rape cultivars.
