石斛兰亲缘关系的SSR分析
Analysis of Genetic Relationship of Ornamental Dendrobium by SSR Marker
摘要
Abstract
The genetic diversity analysis of ornamental Dendrobium is significant in the utilizztion of the germplasm resources.The genomic DNA of 28 popular commercial Dendrobium hybrids were tested with SSR using 11 primer pairs which were screened from 22 primer pairs.A total of 158 polymorphic alleles were obtained,with an average of 14 for each primer pairs.The SSR based genetic similarity ranged from 0.04 to 0.85.The hybrids could be divided 28 hybrids into five groups at 0.295 level similarity coefficient using UPGMA cluster analysis based on SSR molecular markers data.The results of cluster analysis showed that there was a rich genetic diversity and a broad genetic variation in Dendrobium cultivars.The SSR approach was more efficient in molecular analysis of genetic background and relationship of Dendrobium cultivars.关键词
