New breadfruit publication

A new paper on breadfruit is the first major systematic study of this important Pacific crop since Jarret's monograph on Artocarpus published in the 1959. A taxonomic treatment with photographs of key characters for the three species of breadfruit (Artocarpus altilis, A. camansi, and A. mariannensis) is included. This study analyzed 182 trees from 17 Pacific Island groups that are conserved in the breadfruit germplasm collection at the National Tropical Botanical Garden in Hawaii, as well as collections from Papua New Guinea, Pohnpei, Northern Mariana Islands, Singapore, and Malaysia.

Systematics and Species Limits of Breadfruit (Artocarpus, Moraceae)
NYREE J. C. ZEREGA, DIANE RAGONE, and TIMOTHY J. MOTLEY
Systematic Botany 30(3): 603-615.

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.

* Comments:

it is with great interest that i have read your informative article but i wish to bring to your notice that in the soth west of india they are beginng to be plagued with some disease that has affected their breadfruit and coconuts. from the firsthand information given to me the coconut disease was introduced via shipping. i hope these diseases do not reach the shores of the pacific.

This weblog documents the activities of Pacific Agricultural Genetic Resources Network (PAPGREN), along with other information on plant genetic resources (PGR) in the Pacific. The myriad varieties found within cultivated plants are fundamental to the present and future productivity of agriculture. PAPGREN, which is coordinated by the Land Resources Division of the Secretariat of the Pacific Community (SPC), helps Pacific countries and territories to conserve their crop genetic diversity sustainably, with technical assistance from the Bioversity International (BI) and support from NZAID and ACIAR. SPC also hosts the Centre of Pacific Crops and Trees (CEPaCT). The CEPaCT maintains regional in vitro collections of crops important to the Pacific and carries out research on tissue culture technology. The CEPaCT Adviser is Dr Mary Taylor (MaryT@spc.int), the CEPaCT Curator is Ms Valerie Tuia (ValerieT@spc.int).
