高分辨率遗传图谱是分析棉花基因组结构变异和阐明多倍体进化的有效工具。共获得36956个SSR标记，其中11289个已发表，25567个是根据G.树木园和G. raimondii）构建了一个新的遗传图谱。新的高密度遗传图谱包括6009个位点，图谱跨度为3863.97cM，相邻标记间的平均距离为0.64cM。通过同源性分析鉴定出4个倒位（1个在Chr08和Chr24之间，1个在Chr09和Chr23之间，2个在Chr10和Chr20之间）。遗传图谱与两个二倍体棉花的比较分析表明，A基因组与At亚基因组之间的结构变异比D基因组与Dt亚基因组之间的结构变异更广泛。在遗传图谱与G.雷蒙地。四倍体陆地棉和海岛棉染色体组间存在较好的共线性关系，但共检测到16个倒位。这些结果将有助于棉属植物的进化分析。
A high-resolution genetic map is a useful tool for assaying genomic structural variation and clarifying the evolution of polyploid cotton. A total of 36956 SSRs, including 11289 released in previous studies and 25567 which were newly developed based on the genome sequences ofG. arboreumandG. raimondii, were utilized to construct a new genetic map. The new high-density genetic map includes 6009 loci and spanned 3863.97 cM with an average distance of 0.64 cM between consecutive markers. Four inversions (one between Chr08 and Chr24, one between Chr09 and Chr23 and two between Chr10 and Chr20) were identified by homology analysis. Comparative genomic analysis between genetic map and two diploid cottons showed that structural variations between the A genome and At subgenome are more extensive than between D genome and Dt subgenome. A total of 17 inversions, seven simple translocations and two reciprocal translocations were identified between genetic map andG. raimondii. Good colinearity was revealed between the corresponding chromosomes of tetraploidG.hirsutumandG.barbadensegenomes, but a total of 16 inversions were detected between them. These results will accelerate the process of evolution analysis ofGossipiumgenus.
