Abstract:

Sorghum, as one of the main brewing materials in China, plays an important role in the development of national economy. Sorghum anthracnose is one of the main diseases of sorghum throughout its whole life cycle. It is more likely to occur and spread in warm and humid tropical and subtropical cultivated areas, and seriously affects the yield of sorghum and reduces grain quality. For several decades, sorghum pathologists and breeders have made extensive research on the occurrence and prevalence of the disease, including the isolation of sorghum anthrax pathogenic bacteria, the utilization of host resistance and the gene location of resistance to anthracnose in sorghum, some research progresses have been obtained, which laid a foundation for biochemical prevention of anthracnose and breeding varieties resistant to anthracnose. Carrying out research on sorghum anthracnose, exploring more abundant and excellent resistant germplasm resources and reducing the use of pesticides can not only meet the huge demand of China’s natural organic sorghum industry, but also promote the high-yield and high-quality production of sorghum. This review summarizes the distribution and symptoms of sorghum anthracnose, infection mechanism of pathogen, epidemic rules and causes of anthracnose, identification of resistance resources and gene location of sorghum anthracnose, which will enable a better understanding of the interaction between sorghum and Colletotrichum sublineola at the molecular level and provide reference for sorghum anthracnose research.

Key words: sorghum, anthracnose, pathogenic bacteria, disease, resistant resources, gene location
