Abstract
Genetic diversity of Lilium sargentiae was detected in this paper by sequence-related amplified polymorphism (SRAP) marker. One hundred wild samples were collected from 10 places, and 15 SRAP primer combinations were used for determination. NTSYS-pc2.1 and POPGEN1.32 were used for data analysis. The results showed that a total of 170 clear DNA bands were amplified, 163 of which were polymorphic. The proportion of polymorphic loci was 90.58% on the level of species. Nei's (1973) gene diversity (H) was 0.2631, Shannon's Information index was 0.3661, the G(st), was 0.3672, and the genetic distance ranged from 0.2021 to 0.5749. All materials could be clustered into four groups by UPGMA. The results demonstrated that the genetic diversity of L. sargentiae was rich on the level of species, and the genetic diversity within populations exceeded among populations. The correlations of genetic diversity and distribution were significant in L. sargentiae.
