The genetic diversity of the endangered plant Abies yuanbaoshanensis
濒危植物元宝山冷杉的遗传多样性研究

Abies yuanbaoshanensis (Pinaceae) is an endangered species endemic to Yuanbaoshan Mountain , Guangxi, China. Genetic diversity in 43 individuals of the speices was assessed using the amplified fragment length polymorphisms (AFLP) technique. Four primer combinations generated a total of 261 bands, of which 133 were polymorphic (50. 96%). The Nei's gene diversity of the population was 0. 1510, and Shannon's information index was 0. 1735. The results indicate that Abies yuanbaoshanensis has a low level of genetic diversity. This finding provides valuable information for formulating future conservation programs for the species.
