中文摘要：

以＂小米荞×晋荞2号＂杂交组合,通过单粒传获得的245个F_5代重组自交系（命名为SJ-RILs）群体为作图材料,构建SSR遗传连锁图谱。结果显示：350对SSR引物在亲本间有多态性的为59对,多态率为16.9%;多态性引物在SJ-RILs群体共扩增出80个等位变异位点;来自小米荞和晋荞2号等位基因分别占群体总基因型的51.5%和48.5%;采用作图Jionmap4.0软件构建的遗传连锁图总长度为1 106.74cm,含11个连锁群,80个分子标记,其中偏分离标记27个,相邻标记的平均间距为13.83cm。结论：该图谱可为苦荞遗传图谱构建、重要性状QTL的定位和基因组学研究隆奠定基础。

英文摘要：

In this study,245 tartary buckwheat（ F. tataricum） F_5 recombinant inbred lines developed from a cross between Small Rice buckwheat and Jinqiao2（ named as SJ-RILs） population was employed to construct a genetic linkage map with microsatellite（ SSR） markers. Result： Of 350 pairs of SSR primers screened,59（ 16. 9%） were polymorphic between the two parental lines,and totally 80 polymorphic loci were detected in the SJ-RILs population; The alleles from Small Rice buckwheat and Jinqiao2 accounted for 51. 5% and 48. 5% of total loci,respectively; A genetic linkage map of1 106. 74 centimorgans（ cm） was established by Jionmap4. 0 software,which was consisted of 11 linkage groups and 80 SSR markers including 27 segregation distortion markers. The average distance was13. 83 cm between adjacent markers. Conclusion： The genetic linkage map generated in the present study provides a basis for genetic linkage map construction,QTL mapping of important traits and genomic studies in tartary buckwheat.
