Abstract.

 The phylogenetic relationships among 14 Mangifera L. species of Thailand were analyzed by comparing sequences of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA). Parsimony and neighbor joining (NJ) analyses revealed that the common mango (M. indica L.) was closely related to M. laurina Bl., M. sylvatica Roxb., and M. oblongifolia Hook. f. Mangifera foetida Lour. and M. odorata Griff. were also related to M. indica in both parsimonious and NJ trees, although these two species are classified into a different subgenus (subgenus Limus) from the subgenus Mangifera to which M. indica belongs. ITS sequence analysis revealed that several species have nucleotide additivity (two different nucleotides at the same locus) at several sites in the ITS region. Also, M. indica had several polymorphisms among cultivars. This finding may suggest a possibility of hybrid origin of Mangifera species, although Mangifera species are all assumed to be diploid having chromosome number of 2n=2x=40.

Key words: Mangifera, taxonomy, non-concerted evolution, hybridism, allopolyploidy.
