DESIGN AND ASSESSMENT OF NUTRITIONALLY ENHANCED CARROTS WITH UNUSUAL PIGMENTS
OBJECTIVES: Develop high-pigment, high culinary quality genetic stocks and molecular markers for use by the production industry. Grow carrots with high specific activity labeled carotenoids and anthocyanins. Anthocyanins methods optimization. Evaluate bioavailability/metabolism of B-carotene from (HCM) b-carotene-rich carrots, anthocyanins from anthocyanin-rich carrots (HAM) in humans. Evaluate chronic feeding bioavailability of B-carotene lutein, lycopene from speciality carrots. Educate growers, seed comp, and public.
APPROACH: Genetic stocks will be develolped with classical breeding techniques and PCR based markers developed from AFLPs. Selected items will be formally released. Carotenoid and anthocyanin accumulation will be evaluated and carrot produced growth chambers with C-13 label. Labeled carrots will be fed to humans and serum analyzed to determine bioavailability. Production and flavor of selected high pigment carrots will be evaluated in CA desert and inland regions, WA, and WI. Production bulletins and websites will be developed for growers and nutritionists. Extension instructional materials will be developed for the general public.
