Plant material

Two potato genotypes belonging to the Solanum tuberosum L. group andigena were used in this study: Diacol Capiro (also known as R12) and Perla Negra (CIP code N° 391691-96 and called Serranita in Peru), both have semi-erect growth habit. Diacol Capiro is the most widely cultivated variety for fresh markets and for the industry in Colombia. The tuber skin is predominantly red with purple as a secondary color, and the flesh color is cream. Perla Negra was a recently introduced material from the International Potato Center CIP under the international project “Innovation and Development Network” toward the efficient dissemination and pro-poor impact mechanisms with new potato varieties in the Andean zone. Specifically, Perla Negra has a purple skin and a pale yellow flesh and its high content of anthocyanin will be an indicator of potential drought tolerance.
