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 suitable for no-tillage late direct-sowing in Western Sichuan Plain were screened in this study. [Method] Ten major varieties of Brassica napus L. were screened by randomized block design and triplicated plot test with no-tillage 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; other 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 ‘Huayouza10＇, ‘Ningza 11＇, ‘Huayouza 13＇ and ‘Zheshuang 3＇ can be successfully introduced and applied for large-area cultivation in Western Sichuan Plain.展开更多
