棉花黄萎病抗性分子标记辅助选择改良研究进展

Research Progress on Improvement for Verticillium Wilt Resistance by Molecular Marker-Assisted Selection in Cotton

由大丽轮枝菌引起的棉花黄萎病已成为当前我国棉花可持续生产的主要障碍之一。分子标记辅助选择打破传统表型选择的局限性,实现对基因型的直接选择,有助于提高选择效率。然而分子标记辅助选择在棉花抗黄萎病育种中的应用不充分。概述棉花黄萎病抗性分子标记辅助选择改良的研究进展,讨论改良过程中遇到的问题,在总结相关研究的基础上讨论分子标记辅助选择在棉花抗黄萎病育种中的应用前景,以期为我国棉花抗黄萎病分子育种提供有用信息。

Cotton Verticillium wilt caused by Verticillium dahliae Kleb. has become one of the main impediments to cotton sustainable production in China. Molecular marker-assisted selection （MAS） can transform traditional phenotypic selection into direct genotypic selection to improve the efficiency of selection. However, insufficient progress has been made in research to apply molecular markers to MAS of cotton Verticillium wilt resistance. This paper was devoted to make a detailed review that focused on the progresses on improvement for Verticillium wilt resistance by MAS in cotton. Moreover, the problems encountered in practical application of improvement for Verticillium wilt resistance by MAS were discussed emphatically. The promise of MAS in breed for resistance to Verticillium wilt was also discussed in this review. So these research summary might provide very important information for the molecular breeding of resistance to Verticillium wilt of cotton in China.
