To clarify the genetic diversity and genetic structure of a rare and the endangered small population of Ferula fukanensis, it is the basis and prerequisite to develop effective conservation and management strategies. The genetic diversity and structure of 87 endangered plants F. fukanensis from three populations based on 10 pairs of SSR primers with good polymorphism and stable amplification were analyzed respectively. The results showed that small population of F. fukanensis had relatively high genetic diversity, the Nei’s gene diversity index(hS) among the populations was 0.514, the total Nei’s gene diversity index(hT) was 0.516, the observed heterozygosity(Ho) was 0.881, the expected heterozygosity(He) was 0.512, the Shannon information index(I) was 0.836 and the percentage of polymorphic bands(PPB) was 100%, and the genetic differentiation degree of F. fukanensis was very low(Fst=0.007), 95.9 % of the variation of F. fukanensis occurred within populations, and there was no significant correlation between genetic distance and geographical distance, 66.7% of the populations suffered from genetic bottlenecks. The results showed that F. fukanensis had abundant genetic variation and high evolutionary potential. Based on the current situation of this wild population, it is suggested to establish a protected area, and carry out in situ conservation and strengthen ex situ conservation measures such as introduction and artificial breeding to assist the conservation of F. fukanensis. This study can provide theoretical support for the conservation of plant resources of F. fukanensis and has important theoretical and practical significance.
