Rapeseed is one of the primary oil crops in China, which is laden with heavy responsibility to insure the supply of plant oil. Rapeseed oil accounts for over 57% of the oil production from all oil crops in China. In recent years, China faces severe security problem of edible oil, and over 60% are depended on import. The low yield and high production cost of Chinese rapeseed varieties are the main reasons which restrict the development of rapeseed growing in China. So, strengthening the rapeseed breeding technology is the effective approach for developing domestic rapeseed industry. SNP array, a high flux and new technology for molecular breeding, has brought an uncommon opportunity for promoting the development of rapeseed industry. Right now,we own the incomparable research foundations on the sequence of rapeseed and its elementary species and the technology of SNP marker developing, which offer the compelling advantages for developing SNP array. Rapeseed researchers are trying to introduce and develop the domestic platform for SNP array, which will offer the technical support for efficient development of rapeseed breeding.
