[目的]川西平原秋季多绵雨，为避开播种期湿害影响，筛选适合川西平原生态区免耕晚直播的甘蓝型双低油菜新品种。[方法]以10个甘蓝型油菜新品种为试材，采用随机区组排列，3次重复，免耕晚直播，稻草覆盖，进行比较试验。[结果]‘川油58’、‘华油杂10号’和‘宁杂11号’产量高，折合单产3000 kg/hm2以上，综合性状表现较好、生育期短、抗性好、品质优；‘华油杂13号’和‘浙双3号’有高产潜力，单产2775 kg/hm2以上，抗性好、品质优、生育期适中；其他品种较对照减产极显著、综合性状表现较差，抗性较差。[结论]‘华油杂10号’、‘宁杂11号’、‘华油杂13号’和‘浙双3号’等长江中下游优异品种可以成功引种并在川西平原进行大面积推广种植。

[Objective] There are continuous rainy days in Western Sichuan Plain in autumn. In order to avoid the impact of wet injury in sowing period, new varieties of Brassica napus L. with low erucidic acid and glucosinolate content which are suit-able for no-til age late direct-sowing in Western Sichuan Plain were screened in this study. [Method] Ten major varieties of Brassica napus L. were screened by ran-domized block design and triplicated plot test with no-til age late direct-sowing and straw mulching for comparative experiment. [Result] ‘Chuanyou 58’, ‘Huayouza 10’ and ‘Ningza 11’ have high yield (per unit area yield above 3 000 kg/hm2), excellent comprehensive characters, short growth period, high resistance and high quality;‘Huayouza 13’ and ‘Zheshuang 3’ have high yield potential (per unit area yield above 2 775 kg/hm2), high resistance, high quality and moderate growth period; oth-er varieties have extremely significant yield reduction, poor comprehensive characters and low resistance compared with control. [Conclusion] Excellent varieties of Brassica napus L. in the middle and lower reaches of Yangtze River such as ‘Huayouza 10’, ‘Ningza 11’, ‘Huayouza 13’ and ‘Zheshuang 3’ can be successful y intro-duced and applied for large-area cultivation in Western Sichuan Plain.
