来自海岛棉与纤维强度、长度、马克隆值有关的分子标记及其应用
摘要：
本发明涉及分子育种技术领域，具体涉及来自海岛棉海1与纤维强度、长度、马克隆值有关的分子标记及其应用。所述分子标记为NAU5421200和NAU2325240。其中，NAU5421200与棉花纤维强度QTL位点qFS‑C14‑1和纤维长度QTL位点qFL‑C14‑1同时紧密连锁，NAU2325240与棉花纤维马克隆值QTL位点qFM‑C17‑1紧密连锁。qFS‑C14‑1和qFL‑C14‑1同时位于染色体C14上的同一位置，qFM‑C17‑1位于染色体C17上。本发明有助于克服现有育种技术对纤维品质鉴定存在的不足，能提高纤维强度、长度、马克隆值的选择效率，加快优质新品种的培育进程。
摘要（英）：

The invention relates to the technical field of molecular breeding, and particularly relates to sea island cotton originated molecular markers related to intensity, a length and a micronaire value of a fiber and application thereof. The molecular markers are NAU5421200 and NAU2325240, wherein the NAU5421200 is simultaneously and closely linked with a cotton fiber intensity QTL (quantitative trait locus) qFS-C14-1 and a fiber length QTL qFL-C14-1, and the NAU2325240 is closely linked with a cotton fiber micronaire value QTL qFM-C17-1. The qFS-C14-1 and the qFL-C14-1 are simultaneously positioned at the same position on a chromosome C14, and the qFM-C17-1 is positioned on a chromosome C17. The sea island cotton originated molecular markers are helpful for overcoming the defects of an existing breeding technology on fiber quality identification, selection efficiency of the intensity, the length and the micronaire value of the fiber can be improved, and the cultivating process of a high-quality new variety is accelerated.
