[Genetic diversity of Fritillaria from Sichuan province based on ISSR].

Abstract

ISSR marker technique is suitable for the genetic diversity of Fritillaria from Sichuan province. Interspecific identifications among the four original species of Bulhus Fritillariae Cirrhosae recorded by pharmacopoeia of China, and between them and the other species of genus Fritillaria from Sichuan province could not be gained by using ISSR markers technique. In addition, the cluster result of genus Fritillaria had some relationships with the geographical distribution.
