以屋久岛紫薇（ Lagerstroemia fauriei）和3个紫薇（ L．indica）品种‘Pocomoke’、‘Creole’、‘Dallas Red’为亲本，通过严格控制授粉杂交制备了3个F1杂种群体。利用SSR分子标记对3个群体的亲本进行了多态性检测，结果表明：30对SSR引物在屋久岛紫薇×紫薇‘Pocomoke ’杂种群体的亲本中的多态性最高，27对具有多态性，共产生72个多态性位点；结合子代表型性状的分离情况，并利用SSR分子标记对随机抽取的该群体的100个子代进行基因型检测，发现所得到的位点基本符合孟德尔分离比例，故选取该群体作为构建紫薇遗传连锁图谱的适宜作图群体。

We obtained three F1 populations of Lagerstroemia fauriei and three L.indica cultivars,‘Pocomoke’,‘Creole’ and‘Dallas Red’ , by crossing and analyzed the polymorphisms between parents with 30 SSR primers.27 pairs of SSR primers show polymorphisms between L.fauriei and L.indica ‘Pocomoke’, and 72 alleles were generated.Combined with the separation of offspring phenotypic traits, the F1 population of L.fauriei×L.indica‘Pocomoke’ was selected for the con-struction of the genetic linkage map of Lagerstroemia.Then, we investigated the segregation of genotype in 100 progeny of the L.fauriei×L.indica‘Pocomoke’ population by using SSR makers, which are segregated in an expected Mendelian ra-tio.The population of L.fauriei×‘Pocomoke’ is optimal for constructing the genetic linkage map of Lagerstroemia.
