SNP分子标记技术研究进展及在甜菜育种中的应用
A Review of Research Advances in Sugar Beet SNP Molecular Marker Technology and Its Applications in Breeding
摘要
Abstract
SNP(Single Nucleotide Polymorphism)molecular markers,with their advantages of high stability,high density,and high throughput,have become a core technology for sugar beet genetic improvement and precision breeding.This article systematically reviews the technical principles of sugar beet SNP molecular markers,experimental implementation schemes,and their application progress in genome-wide association studies(GWAS)of important traits such as sugar content,salt tolerance,and pest resistance.It also addresses key challenges in current sugar beet SNP research,including relatively low polymorphism,difficulties in dissecting complex traits,and the trade-off between cost and throughput.Strategies such as integrating multi-omics data,developing dedicated SNP chips,and optimizing medium-to high-throughput genotyping technologies are proposed.Finally,the prospects of SNP molecular markers in sugar beet whole-genome selection breeding,localized germplasm innovation,and multi-omics collaborative analysis are discussed,aiming to provide theoretical foundations and technical support for molecular breeding in sugar beet.关键词
