Population genetics and species limits of wild and cultivated Artocarpus odoratissimus Blanco (Moraceae): insights into the domestication of an underutilized crop.

The genus Artocarpus J.R. Forst. and G. Forst. (Moraceae) contains about 70 species of monoecious trees, with a center of diversity in the lowland tropical forests of Malesia. In addition to well-known species such as A. altilis (Parkinson) Fosberg (breadfruit) and A. heterophyllus Lam. (jackfruit), the genus contains numerous other underutilized crops. Among these is Artocarpus odoratissimus Blanco. Native to the lowland dipterocarp forests of Borneo, A. odoratissimus is widely cultivated in the Malaysian state of Sabah for its fragrant, edible fruits (syncarps). A putative wild form is characterized by smaller syncarps, less frequent flowering, and different vegetative characters, but the genetic diversity and domestication history of this species have not been previously characterized. We present preliminary results of a population genetic and phylogenetic analysis of wild and cultivated A. odoratissimus from Sabah based on nuclear and chloroplast SSRs and sequences to elucidate the genetic diversity, intra-species relationships, and domestication history of this locally prized but underutilized crop.
