ResumoISSR molecular markers were used to analyze 218 individuals of 8 Haloxylon ammodendron(C.A.Mey.)Bunge populations in Xinjiang and 222 polymorphic sites were amplified with 11 primers in these tested materials;the percentage of the polymorphic sites made up 89.23% and the percentages of the polymorphic sites in the eight populations differed within 23.42%～45.05%;the highest percentage of polymorphic sites appeared in Wusu population and the lowest one appeared in Tuokexun populations.Analysis of genetic variations showed that the coefficient of gene differentiation Gst was 63.78 on species level.Among the populations,the gene flow(Nm)was(0.284 0),the Shaanon diversity index(I)was 0.506 0 and Neis gene diversity(H)was 0.336 2.It was genetically shown that there was a short genetic distance between Wusu and Mosuowan populations.
