In the lower reaches， it was 3 381.28kg/hm2 ， 16.83% higher than the control. The growth period was 1.3 to 1.6 days shorter than that of the control. It exhibited strong lodging resistance，moderate resistance to fungal diseases，and high resistance to viral diseases. The average oil content was 45.74% ，with erucic acid at 0.29% and glucosinolate content at 22.07μmol/g . This variety is a high -yielding and multi -resistant rapeseed cultivar suitable for winter cultivation in the upper，middle，and lower reaches of the Yangtze River.
