Abstract
A study was made by Instituto Boliviano de Tecnología Agropecuaria IBTA, to show the concenience of potato seed selection in grower's fields at altitudes over 3.000 meter over sea level. The method utilized traditional practices of farmers as well as their own native cultivars. The cultivars Sani Imilla, Imilla blanca, Manzana, Huaycha paceña and Malcacho showed an average yield increase of 39 percent after using the field selected seeds. Each cultivar had its own virus symptoms expressions, and some were easier to detect by visual selection. The percent of yield increase after selection was also variable according to the cultivar utilized. The presence of pests in the fields during various years depended much on climatic conditions.
Additional Index Words: cultivar, virus, pests, climatic, native.
