棉花育种行业创新与进展

Genetic and Breeding Progress of Cotton

对2017年国内外棉花遗传育种领域取得的重要研究进展进行了概括性评述。棉花基因芯片技术得到了广泛应用,一批重要产量、品质性状基因获得定位和克隆。棉花全基因组关联分析(GWAS)取得重大突破,陆地棉高密度遗传图谱构建取得重大进展,棉花芽黄、纤维品质性状基因的精细定位及克隆取得较大进展,在棉花转基因新方法、转基因抗虫、抗除草剂新材料等方面进展显著。文中并进一步结合我国棉花发展现状、未来趋势与所面临的机遇,提出了我国棉花发展应采取的一些对策。

In this review ,we comment on the progress in cotton genetic and breeding in 2017. The cotton chip- SNPs were commercially applied in genotyping, lots of QTL/genes related to fiber yield and quality traits were iden- tified and cloned, Significant progress was made in cotton GWAS research, construction of upland cotton high densy genetic mapping, and significant advance in fine mapping and cloning the genes related to cotton virescent and fiber quality, and the great achievements were made in cotton transgenetic new technology and materials for resistance to bud worm and herbicide. Meanwhile, combined with cotton production situation, future needs and new opportunity in china ,we propose the some solutions, which need to be considered in the long term research.
