Abstract:

Sorghum, as one of forage crops, has won great attention in many countries and regions all over the world. Due to its characteristics of strong drought resistance and high water use efficiency, sorghum has become the most predominant forage crops in arid areas. The lignin content of bmr sorghum is 5%~50% lower than that of normal sorghum. Low lignin content can improve palatability and increase digestibility of forage. Therefore, it has aroused extensive attention by sorghum breeders all over the world. Great progress has been made in improving forage production, its quality, feeding efficiency and about the gene of bmr sorghum. The bmr gene has been successfully transferred into normal sorghum and sudangrass. BMR hybrid forage variety with high yield, superior quality has been released and produced commercially. It has a bright prospect for utilization.
