摘要
全基因组关联分析(GWAS)是挖掘作物重要性状遗传信息的主要手段。随着测序技术的快速发展,开发单核苷酸多态性(SNP)标记的成本大幅降低,以连锁不平衡(LD)为遗传基础的GWAS技术已被广泛用于研究作物的农艺、品质和抗性等复杂性状。近年来GWAS 技术已成功运用到对大豆重要性状的遗传解析上,并取得了一系列的研究进展。在简要介绍GWAS技术的原理和实施方法的基础上,总结分析了近年来其在大豆重要农艺性状、品质性状和逆境抗性性状上的遗传学研究进展及应用前景。
Genome-wide association study(GWAS)is the main method to mine genetic information of important traits in crops. With the rapid development of sequencing technology,the cost of developing single nucleotide polymorphism (SNP) markers has been greatly reduced. GWAS technology based on linkage disequilibrium(LD)has been widely used to study the complex traits of agronomy,quality and resistance of crops. In recent years,GWAS technology has been successfully applied to the genetic analysis of important traits of soybean,and a series of research progresses have been made. Based on the introduction of principle and implementation method of GWAS,the author summarizes and analyses the recent advances in genetic research on important agronomic traits,quality traits and stress resistance traits in soybean and the application prospects.
