Abstract:

As vegetable, feed and ornamental plants, Brassica crops have important economic value. With the development of the rapid development of molecular biology and genomic sciences, research on molecular breeding in Brassica crops achieved significant progresses. This paper summarized the present application and research development of molecular breeding in Brassica crops, involving molecular marker-assisted breeding, transgenic research, and molecular design breeding.Furthermore, the exiting problems of Brassica crops molecular breeding and solutions for the problems were analyzed and proposed. Those provided theoretical and practical reference for the study on molecular breeding of Brassica crops.

Key words: Brassica crops, molecular breeding, progress

摘要：
