In this study, the genetic diversity and population structure of 4 wild ancient tea tree ( Camellia taliensis ) populations at different altitudes (2,050, 2,200, 2,350, 2,500 m) in Qianjiazhai Nature Reserve, Zhenyuan country, Yunnan province, were investigated using EST-SSR molecular markers to compare their variation against altitude. total, 182 alleles detected across all loci, ranging from 6 25. The top one informative SSR was CsEMS4 with polymorphism information content (PIC) 0.96. species high, 100% loci being polymorphic, an average Nei’s gene H 0.82, Shannon’s index I 1.99. By contrast, level, relatively low, values 0.79 1.84, respectively. Analysis variance (AMOVA) revealed a minor differentiation (12.84%) among populations, most (87.16%) within populations. Using analysis, we found that germplasm divided into three groups, there substantial exchange these groups altitudes. Divergent habitats caused by high flow played important roles which will provide new opportunities for promoting protection potential utilization.
