ABSTRACT
Objective:
To evaluate the genetic diversity of germplasm resources for Amomi Fructus from various habitats in different phenotypes.Methods:
Inter-simple sequence repeats (ISSR) markers were used to analyze the genetic diversity and the genetic relationship among 21 samples Amomi Fructus collected from Yunnan, Hainan, Guangdong, and Fujian Provinces; At the same time, the phenotypic characters of 16 Amomum villosum samples were measured in height, stem diameter, blade number, and blade size, etc. Then cluster analysis on all populations of Amomi Fructus was carried out based on the above data.Results:
Eleven primers selected from 60 ISSR-primers were used for amplification and a total of 54 DNA bands were obtained,including 22 polymorphic bands. At species level, the average percentage of polymorphic bands (PPB) was 40.74%, Nei's gerne diversity (H) was 0.116 1, Shannon's information index (I) was 0.184 2. There was a little difference of morphological characteristics.Conclusion:
The genetic diversity of germplasm resources in Amomi Fructus is lower.
