Abstract

Breadfruit (Artocarpus, Moraceae) is an important staple in Oceania and throughout much of the tropics. Interpretations of species delimitations among breadfruit and its closest relatives have varied from recognition of one to several species. To better understand the systematics and ultimately the origins of breadfruit, we considered evidence from molecular data. Amplified fragment length polymorphism data for 261 individuals of breadfruit, its closest relatives, putative hybrids, and nine outgroup taxa were analyzed using neighbor joining and parsimony analyses. Three species, A. altilis (domesticated breadfruit), A. camansi, and A. mariannensis, are recognized and the existence of hybrids (A. altilis x A. mariannensis) verified. A revised treatment based on the molecular results, as well as morphological and geographical considerations, is presented.
