Identification of candidate genes for key fibre-related QTLs and derivation of favourable alleles in Gossypium hirsutum recombinant inbred lines with G. barbadense introgressions
海岛棉 基因组组分 遗传作图群体
2024/5/17
该研究以渗入了海岛棉基因组组分的优质种质鲁原343为亲本，构建了包含239个重组自交系的遗传作图群体，利用SLAF标签构建了高密度遗传图谱，结合7个环境的表型数据，共鉴定104个纤维品质和产量性状QTLs，其中66个QTL共定位于19个QTL簇中。该研究团队通过进一步对鲁原343进行全基因组深度测序，解析鲁原343的遗传组成及其对纤维相关性状的遗传贡献，发现来自G. hirsutum races（...
Mapping of QTLs Controlling Carbon Isotope Discrimination in the Photosynthetic System using Recombinant Inbred Lines Derived from a Cross between Two Different Rice (Oryza sativa L.) Cultivars
