Abstract:

Salinity stress is a main factor affecting plant growth and crop yield. It is a simple and effective way to solve salt damage by genetic improvement. This paper reviewed the salt\|tolerant germplasm resources, localization of salt\|tolerant genes (QTLs), cloning, transferring and utilization of salt\|tolerant genes through gene engineering technology. The paper also prospected the future of research  on sorghum and salt tolerance, so as to provide theoretical basis for genetic improvement of salt\|tolerant ability of sorghum and other crops. It could also solve the salinity stress problem, limitting crop yield and quality in agricultural production.

Key words: salt tolerance, gene mapping, gene transferring, Sorghum bicolor

摘要：

盐害是影响植物生长和作物产量的主要因子之一，通过遗传改良提高植物的耐盐性是简单有效解决盐害的主要途径。综述了到目前为止筛选鉴定出的主要耐盐碱资源；耐盐碱基因（数量性状位点）的定位、克隆及通过基因工程技术进行耐盐基因在不同作物中的转移利用情况；并对高粱耐盐碱的研究前景进行了展望。以期为高粱等作物的耐盐碱改良研究提供理论依据，从而促进对土壤盐渍化影响农作物产量和质量的重大农业问题的解决。
