Genetic diversity analysis of 27 compositae germplasms based on ISSR molecular markers
In order to preserve and identify compositae germplasm resources,ISSR markers were used to analyze the genetic diversity and genetic relationship of 27 compositae germplasms.The polymorphisms were analyzed by NTSYS-pc 2.1,the genetic tree was constructed by UPGMA.The results showed that 10 primers were screened and 255 clear polymorphic bands were amplified,accounting for 94.80％of the total bands.The UPGMA cluster analysis showed that the genetic similarity coefficients of 27 compositae germplasms ranged from 0.36 to 1.00,and the 27 compositae germplasms could be divided into three categories at 0.40 similarity coefficient.The 27 compositae germplasms have rich genetic diversity and the 10 ISSR primers can be used for molecular identification of germplasm resources.
