Abstract

ISSR molecular markers were used to detect genetic diversity of 105 individuals in four populations of Haloxylon persicum. 171 polymorphic bands were induced by amplication primers. Percentage of polymorphic bands is 84 . 85% and the difference among four populations ranged from 33 . 92% to 40. 35%. Shannon’s indices of diversity (I) is 0. 3518 and Nei’s gene diversity (h) is 0. 3482 respectively. Genetic variance analysis showed that the coefficient of gene differentiation in the species is 0. 6238 and the gene flow is 0.3016 among populations. Genetic distance and cluster analysis indicated that the populations of Ganjiahu and Tulufan had the smallest genetic difference.
