In order to study the effects of cold on the quantity and quality characteristics of 21 cultivars of canola a field experiment was carried out at Research Center of Zanjan in 2006 based on randomized complete block design with 4 repetitions. In order to identify the best cultivare in the point of view of resistence to cold, agronomic characters like grain yield, oil content, 1000-seed weight, number of subsidiary stalk, height of shrub and growing before starting cold of winter have been studied. Results showed that the highest grain yield was related to Modena and ARC-91004 with 3624 and 3613 kg ha-1, respectively. The highest oil content was observed in Sw.0756 cultivare which had acceptable grain yield. Considering traits related to cold tolerance in area Modena cultivare had appropriate growth before winter.
