Based on the variety data (2000-2010) from Sichuan province, the characteristics of oilseed rape (Brauica napus L. ) were analyzed in this paper. The results showed that the numbers of oilseed rape ( B. Napus) variety and the percentage of hybrid or double-zero variety increased obviously in recent 10 years. Plant height or total growth season indicated a adding or elongation tendency. Yield or potential productivity increased obviously because of the increment for pods per plant but little change for seeds per pod or thousand-grain weight. The quality of oilseed rape variety was improved step-by-step especially in oil length but the disease-resistance still was at low level.%本文利用2000 ～2010年油菜审定品种资科,分析了近10年来四川省甘蓝型油菜育成品种的特点.结果表明,近10年来四川省油菜品种数量明显增多,杂交化、双低化发展迅速,品种株高呈现升高、全生育期呈现延长趋势；油菜品种的单株角果数明显增加,每角果粒数也有所增加,千粒重仅略有降低,因此,油菜单位面积产量和生产潜力明显提高；油菜品种品质得到有效改善,含油率稳步增加,但抗病性(病毒病、菌核病)总体上仍处于(较)低水平.
