Genetic inter-relantionships among species of genus Spondias based on AFLP markers

The goal of this study was to build a phenogram with thirty individuals of six Spondias species, sampled in three different locations, based on 120 AFLP markers of EcoR1/Mse1 primers combinations in order to clarify the inter-relationship among these species, to subside the establishment of economic grown of these species and to support genomic studies of these species. The UPGMA phenogram of Jaccard coefficient was supported by a cophenetic value of 0.925 and the outside location of the two outgroups species Mangifera indica and Schinopsis brasiliensis, from the Anacardiaceae family. All individuals of S. cytherea, S. tuberosa and S. purpurea were closely grouped independently of the sampling location, while four out six individuals of Spondias sp (umbu-cajá) and S. mombin were hold together and two other were placed outside of the groups. The two individuals of Spondias sp (umbuguela) were not closely positioned in the phenogram. The phenogram position of umbu-cajá and umbuguela, between S. tuberosa and S. mombin, and the percentage of similarities among 50 and 60% suggested that umbu-cajá and umbuguela could be hybrids of these two species. The produced phenogram suggested that S. cytherea was the most divergent Spondias species.
