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).

Carotenoids in Marshall Islands pandanus
Englberger L, Aalbersberg W, Schierle J, Marks GC, Fitzgerald MH, Muller F, Jekkein A, Alfred J, Velde NV. 2005. Carotenoid content of different edible pandnaus fruit cultivars of the Republic of the Marshall Islands. Journal of Food Composition and Analysis. In press.
As Vitamin A deficiency (VAD) is a serious problem in the Republic of the Marshall Islands (RMI), it is important to identify locally-grown acceptable sources of vitamin A. Pandanus fruit, a traditional Marshallese staple food, has yellow-orange coloration suggesting substantial carotenoid content. However, few of the many Marshallese cultivars were previously analyzed for nutrient content. Thus, this study was conducted in order to identify carotenoid-rich Marshallese pandanus cultivars that could be promoted to alleviate VAD. Ethnography was used to select cultivars and assess acceptability. Thirteen cultivars were analyzed by two laboratories for a- and beta-carotene and other carotenoids using high performance liquid chromatography. The cultivars contained a range of carotenoid levels (21 to 902 mg beta-carotene/100 g), with higher levels in cultivars having deeper yellow-orange colored fruit; 10 cultivars had significant levels meeting estimated vitamin A requirements within normal consumption patterns. There was excellent agreement between the laboratories' results. Pandanus has been increasingly neglected in recent years, but is still well-liked and considered a Marshallese health food. The promotion of carotenoid-rich culturally-acceptable pandanus cultivars could contribute to alleviating vitamin A, micronutrient, and chronic disease problems in the RMI and other Pacific contexts, particularly atoll islands, where pandanus is an important food.
