Belonging to the recessive genic male sterility hybrid rape in Brassica napus L., Zhuoyou No.11 is characterized for its semiwinterness, reniform cotyledon, flourishing lobed leaves, wide parietal lobe, and obvious leaf margin serrate. With compact plant type, resistance to stalk break, mid-length pods and great 1 000 grain weight, it has the advantages in high and stable yield, high oil content, and high protein content. During the hybrid seed production, the isolation distance should be over 1 000 m, and seedling transplantation is adopted by transplanting the male parent first and then planting female parent with the line-ratio of 1：3-4, and cultivation and management measures are in accordance with the high yield standard of growth in autumn; about 50% of the fertile plants in the female parent rows should be removed timely and completely before the flowering stage, and picking off the flower stalks of male parents can extend flowering time, and artificial pollination or bees release can improve the seed setting rate.
