| Abstract: | The phylogenetic relationship of 13 Mangifera species collected in Thailand were examined. Among these species, M. foetida, M. odorata, and M. sylvatica have been cultivated as fruit crops for local markets in Thailand, as well as M. indica (common mango). The other nine wild species also seem to have potential values as rootstocks and breeding materials for tolerance to critical environmental conditions. By restriction fragment length polymorphism (RFLP) analysis of a particular region of cpDNA, these species were classified into two groups. The first group consisted of M. indica and M. sylvatica, 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 study indicated low diversity in the amplified region of cpDNA among Mangifera species tested, even though the species in the second group were scattered to different subgenera and sections. |
