Genetic diversity, population structure, pollen morphology and cross-compatib…

A total of 85 Chinese Cymbidiums and one Zygopetalum were collected and analysed using 29 simple sequence repeats (SSRs) and 12 intersimple sequence repeats (ISSRs). These Chinese Cymbidiums are some of the most popular cultivars in market. The pairwise genetic distance between these accessions averaged 0.897, ranging from 0.259 to 1.000. A model-based clustering analysis revealed five genetic …
