Abstract: The African tulip (Spathodea campanulata) is a monophyletic species native to tropical forests of sub-Saharan Africa belonging to family Bignoniaceae. Although its endemism in sub-Saharan Africa, it is listed as potential alien invasive species in Pacific, Indian and Caribbean, but also Singapore, Papua New Guinea and Australia. The expansion of its range from ornamental to invasive is being observed in South India. In this study, RAPD based DNA markers have been used to determine genetic diversity of the monophyletic species. About 14 populations were studied from 6 states of South India using 41 random decamer primers. The total number of 517 bands were scored which are generated by 41 primers producing 12.6 bands on an average per primer, of these 517 bands produced 379 were polymorphic showing 73% polymorphism revealing higher level of genetic polymorphism in the study population. The similarity coefficient ranged from 0.312 to 0.837 and the dendrogram constructed by the UPGMA based on Jaccard’s similarity matrix farmed two clusters. In the present study, results showed the high degree of genetic diversity within the populations of S. campanulata supporting high degree of adaptation and its range expansion from ornamental to possible invasive species in South India.
