Zhongyouza No.2, a cytoplasmic male sterile three-line rapeseed hybrid, was bred through the methods of test-crossing, induced mutation and crossing. Its parental material was from Shan 2A cytoplasmic male sterile line of Qinyou No.2. The variety possessed the characteristics of high-yield, stable yield, good quality, disease resistance (tolerance) and extensive adaptability. In Regional Trial of Hubei and National Regional Trial, the Zhongyouza No.2 gave 2 926.43kg/hm 2 and 2 318.18kg/hm 2 of average yield, which outyielded the control variety Zhongyou 821 by 19.73% and 13.94%, respectively. The erucic content of Zhongyouza No.2 was 0.90%, and the glucosinolate content was 20.70μmol/g in commercial seed. It was registered by the Hubei Crop Variety Approval and Chinese Crop Variety Approval in 2000 and 2001, respectively.
