Analysis of phylogenetic relationships in Mangifera by restriction site analysis of an amplified region of cpDNA

The phylogenetic relationship of 13 Mangifera species collected in Thailand were examined. Among these species, M. foetida, M. odorata, and M. sylvati ca have been cultivated as fruit crops for local markets in Thailand, as we ll as M. indica (common mango). The other nine wild species also seem to ha ve potential values as rootstocks and breeding materials for tolerance to c ritical environmental conditions. By restriction fragment length polymorphi sm (RFLP) analysis of a particular region of cpDNA, these species were clas sified into two groups. The first group consisted of M. indica and M. sylva tica, and the second group consisted of M. caloneura, M. cochinchinensis, M . collina, M. flava, M. foetida, M. gedebe, M. griffithii, M. macrocarpa, M . oblongifolia, M. odorata, and M. pentandra. The species belonging to the same group are monomorphic for 20 restriction enzymes tested. The present s tudy indicated low diversity in the amplified region of cpDNA among Mangife ra species tested, even though the species in the second group were scatter ed to different subgenera and sections.
