Abstract

VALENCIA-FLOREZ, Luis et al. Influence of storage conditions on the quality of two varieties of native potato (Solanum Tuberosum group phureja). Dyna rev.fac.nac.minas [online]. 2019, vol.86, n.209, pp.49-55. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v86n209.72958.

Native varieties present the opportunity to recover biodiversity and contribute to food security in regions of low development. These varieties, however, have not been studied sufficiently. The varieties of native Curiquinga and Ratona Morada potatoes cultivated in the department of Nariño are subjected to different storage temperatures to observe the behavior of characteristics such as moisture, weight loss, glucose content and ascorbic acid. The Ratona Morada variety better conserved its characteristics in refrigeration, deteriorating faster in incubation, while the Curiquinga presented greater deterioration in refrigeration than in room temperature and incubation. Further studies of post-harvest storage in native varieties is recommended in order to link production with processing that generates additional value to agroindustrial chains, conserve these genetic resources, and provide alternatives for small producers.

Keywords : native potatoes; post-harvest; storage.
