Origin and diversity of an underutilized tropical fruit tree, Cempedak (Artocarpus integer, Moraceae), and its putative wild relative (Artocarpus integer var. silvestris Corner) .
Loss of crop genetic diversity is a global concern because of its impacts on food security and agroeconomies, especially in developing countries. Conservation of wild crop relatives and identification of centers of diversity are critical efforts to maintain genetic resources and prevent crop failures. The genus Artocarpus J.R. Forst. and G. Forst. (Moraceae) contains about 70 species, including the well-known tropical tree crops breadfruit (A. alitlis (Parkinson) Fosberg) and jackfruit (A. heterophyllus Lam.). The underutilized tropical fruit tree, “cempedak” (Artocarpus integer (Thunb.) Merr.), is a major crop in Malaysia but the distribution of genetic diversity in the crop and its putative wild relative, “bangkong” (Artocarpus integer var. silvestris Corner), have not been studied. Furthermore, the widespread cultivation of cempedak in Peninsular Malaysia, along with records of bangkong in literature and herbaria, suggest that this region may be the origin of cempedak domestication. We used microsatellite markers to analyze population genetic structure in cempedak and bangkong populations in Malaysia, and to elucidate their relationship.
