Examining the Origin of Edible Lansium domesticum Corrêa.

Lansium domesticum, Meliaceae, an edible fruit from Southeast Asia grows wild and has also been cultivated by farmers in the region. Few studies have examined the origin of L. domesticum. In this study, the morphological traits and genetic diversity were analyzed from three major sites in Thailand. The single strand conformational polymorphism (SSCP) technique was used to analyze the relationship among varieties of L. domesticum. Three specific primers of glyceraldehyde 3 phosphate dehydrogenase (G3PDH), abscissic acid insensitive3 (ABI3), and isocitrate dehydrogenase (IDH) showed high polymorphism. The results indicate that though most of the overall features of this type of L. domesticum were quite similar, there were some distinguishable differences in the fruit anatomy. The results show that edible L. domesticum varieties are heterozygous and triploid. The chloroplast molecular markers indicate that most edible L. domesticum varieties share the same maternal plant. However, the paternal side of this group has not yet been established. Future studies should examine more levels of genetic diversity by collecting more plant samples from similar or closely related species around the Indo-Malaysian Peninsula.
