摘要

Sorghum [Sorghum bicolor (L.) Moench] is an important cereal crop grown for its diverse uses. Global sorghum production andproductivity is affected by various stresses notably by biotic factors such as diseases, weeds and insect pests. Anthracnose causedby the fungal pathogen Colletotrichum sublineolum Henn. (formerly known as C. graminicola [Ces.] G.W. Wilson), grain mold, leafblight, rust and smut are among the most import diseases of sorghum, while stem borer, shoot fly, termites and birds are notablepests of the crop. Sorghum anthracnose occurs in epidemic proportions under high temperature and humidity conditions causingyield losses reaching up to 67% in susceptible varieties. Sorghum shows considerable genetic variation. A large number of landracesare exploited in breeding for disease resistance and better agronomic performance. This review presents literature on breedingsorghum for anthracnose resistance and associated challenges and opportunities. Information presented in this paper may guidefuture breeding of sorghum varieties incorporating farmer needs and preferences.

Wilson），谷物霉菌，叶枯病，锈病和黑穗病是高粱最重要的输入病，而茎bore，枝条蝇，白蚁和鸟类是该作物的主要特征。高粱炭疽病在高​​温和高湿度条件下以流行的比例出现，导致易感品种的产量损失高达67％。高粱显示出相当大的遗传变异。为了育种抗病性和更好的农艺性能，开发了许多地方品种。这篇综述提供了关于高粱炭疽病抗性以及相关挑战和机遇的文献。本文提供的信息可能会指导结合农民需求和喜好的高粱品种的未来育种。
