There are continuous rainy days in autumnal in Western plain of Sichuan, to avoid the impact of Wet Injury in sowing days and to screen new varieties of Brassica napus L. with low erucidic acid and glucosinolate content, suitable for no-tillage late direct-seeding in Western plain of Sichuan. Ten varieties of Brassica napus L. were screened by randomized block design with triplicated plot, no-tillage late direct-seeding and straw mulching. The results showed superiority of varieties ‘Chuanyou 58’, ‘Huayouza 10’ and ‘Ningza 11’ over the other varieties as revealed by high-yield(over 3000 kg/hm2), short growth stage, better resistance, quality and integrated traits; varieties ‘Huayouza 13’ and ‘Zheshuang 3’ have high yield potential(over 2775 kg/hm2), better resistance and quality, moderate growth stage; the other varieties have significant yield reduction less than control, poor expression of comprehensive characters and resistance. The excellent varieties of the middle and lower Yangtze River such as ‘Huayouza 10’, ‘Ningza 11’, ‘Huayouza 13’ and ‘Zheshuang 3’ etc. could successful introduce and large area plant in Western plain of Sichuan.
