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).

New banana nutritional content paper
From Dr Lois Englberger.
We would like to share with you that our paper titled "Carotenoid content and flesh color of selected banana cultivars growing inAustralia", by L Englberger, R B H. Wills, B Blades, L Dufficy, J W. Daniells, and T Coyne is now published in the Food and Nutrition Bulletin December 2006 issue.
The paper's title refers to banana cultivars grown in Australia, but the work also involves cultivars from the Pacific.
The paper should soon be on the journal’s website.
Let me know if you would like the pdf file; it was kindly provided by Susan Karcz, Managing Editor. Thank you again Susan!
Here below is the abstract, thanks again all to those involved in this project!
Background: Research in Micronesia indicates that yellow- and orange-fleshed banana cultivars contain significant levels of provitamin A carotenoids.
Objective: To identify further banana cultivars that may be promoted to alleviate vitamin A deficiency and chronic disease problems.
Methods: Ripe fruit of banana cultivars growing in Australia (sourced mostly from a field research collection) were assessed for carotenoid content and flesh color. Ten cultivars with yellow or yellow/orange flesh color (including common cultivars of Southeast Asia and the Pacific Islands) were selected and compared to two cream-fleshed cultivars, including Williams, of the Cavendish group, the most commonly marketed banana world-wide. Carotenoid content was analysed using HPLC. Flesh color was analysed using HunterLab colorimetry.
Results: The yellow/orange-fleshed Asupina (a Fe’i banana) contained the highest level (1430 ?g/100g) of ?-carotene, the most important provitamin A carotenoid, over 20 times higher than that of Williams. All ten yellow or yellow/orange-fleshed cultivars (Asupina, Kirkirnan, Pisang Raja, Horn Plantain, Pacific Plantain, Kluai Khai Bonng, Wain, Red Dacca, Lakatan, and Sucrier) contained significant carotenoid levels, potentially meeting half or all of estimated vitamin A requirements for a non-pregnant, non-lactating female adult within normal consumption patterns. All were acceptable for taste and other attributes. The cream-fleshed cultivars contained minimal carotenoid levels. There was a positive significant correlation between carotenoid content and deeper yellow/orange coloration indicators.
Conclusions: These yellow- or yellow/orange-fleshed carotenoid-rich banana cultivars should be considered for promotion in order to alleviate vitamin A deficiency and chronic disease in susceptible target communities and to provide variety and enjoyment as exotic fruits in both developing and industrialized countries.
And here's a comment from Judy Mieger: Reading a bit of this color stuff brought 2 things to mind----Dr. Bill Sears is a wonderful pediatrician/author/breastfeeding advocate/father of 8!! who has several children's nutrition books out that are fantastically popular----and as I remember hearing he talks about eating a rainbow every day (or something...)---such a great concept for kids. … COLOR is something I can get into!----and even as interested in nutrition as I am, learning nutritional details is boring to the average person like me----but give me the Color Connection any time and I'll perk up! :) (I can't be the only one...) All good wishes for a healthy karat-filled 2007, Judy
