Cluster Analysis of Nelumbo Accessions Based on RAPD Markers

Thirty-two Nelumbo accessions were analyzed with RAPD markers. The result showed that three cultivar groups were clustered: lotus with flowers (Group Ⅰ), lotus with seeds(Group Ⅱ)and lotus with root(Group Ⅲ).It was similar to the traditional horticaltural classification. No difference was observed between N. lutea and lotus accessions with flower (N. nucifera). Lotus with flowers, lotus with seeds and lotus with root might be derived from different wild lotus.
