[Genetic diversity of Citrus succosa Hort. Ex Tanaka from seven provinces as revealed by AFLP analysis].
Using 28 selected primer combinations, 12 accessions of Bendizao tangerine from seven provinces were investigated by AFLP analysis. A total of 882 genetic sites were detected, among which 192 were polymorphic. Using Huangyan Bendizao as contrast, the polymorphic sites of the other 11 accessions from seven provinces are not very high (3.5%-10.54%), and the number of different sites between accessions from other provinces is higher than that from Zhejiang province, which indicates that the ecological difference can partially contribute the formation of the genetic diversity. Genetic distance and dendrogram showed considerably close relatedness among the 12 accessions, and the max genetic distance was 0.229. The genetic analysis of the 12 accessions from seven provinces can provide useful information for the relationship between the formation of genetic variation and environmental difference and can facilitate the genetic improvement of this cultivar.
