Abstract or Summary
  • Though currently relatively unknown outside Latin America, Andean root and tuber crops are rapidly gaining interest elsewhere. Tubers are a major food and important sources of nutrition in South America and have potential in countries outside their center of origin. We conducted a two-part study on oca (Oxalis tuberosa), mashua (Tropaeolum tuberosum), ulluco (Ullucus tuberosus), and mauka (Mirabilis expansa) planting and harvesting over a two-year period to study the feasibility of cultivation and use in the Pacific Northwest (PNW). We also observed crops and interviewed key informants in Peru and Ecuador, and in the PNW concerning cultivation, loss of genetic variation and preservation efforts, and usage and perceptions. In the PNW, we also investigated commercial potential and general public knowledge and interest. Our findings suggest that these plant species will grow and produce tubers in the PNW and can also produce viable seed, which is extremely important for breeding varieties better adapted to the PNW and other similar growing regions. The loss of genetic diversity of oca, mashua, and mauka observed in Peru and Ecuador could potentially be counteracted by their cultivation and genetic improvement in the PNW, where there is an increase in cultivation, sales, and interest. Key Words: oca; mashua; ulluco; mauka; Oregon
