Research Progress on Drought Resistance of Sorghum
Drought is one of the important factors that limit plant productivity and threaten food security.As a global staple food and forage crop,sorghum(Sorghum bicolor L.Moench)has good characteristics in drought resistance along with abilities to survive in harsh environments,and is widely planted in arid and semi-arid areas,which give it important research values in the field of crop drought resistance.It is of great signifi-cance in accelerating breeding process of drought-resistant varieties and increasing drought resistance and yield of sorghum to further analyze the morphological and physiological characteristics under drought stress,identify and screen the excellent drought-resistant varieties,and dig out drought-resistant genes.In this paper,the re-search progress in drought resistance of sorghum was reviewed from influences of drought stress on sorghum growth,physiological responses of sorghum to drought stress,identification methods and indexes,molecular biology,and improvement methods,and the prospect of research direction of drought resistance in sorghum was proposed,in order to lay a foundation for further study of the morphological and physiological characteris-tics and molecular mechanisms of drought resistance in sorghum.
