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（...
Examining two sets of introgression lines across multipleenvironments reveals background‑independent and stably expressedquantitative trait loci of fiber quality in cotton
陆海渐渗系 纤维品质 QTL 棉花
2024/5/17
首次利用两套陆海渐渗系鉴定纤维品质QTL，探讨遗传背景和环境对纤维品质QTL表达的影响，揭示了遗传背景对纤维品质QTL表达的影响明显大于环境因素；在全基因组上鉴定到稳定的QTLs 109个，不受背景影响的QTLs 9个。其中，61个稳定的QTLs，包括2个不受背景影响的QTLs，是新发现的；鉴定到19个含有多个纤维品质性状的优良等位基因的QTL簇，为进一步棉花分子育种提供了重要信息和理论指导。
