The physicochemical characteristics of potato tubers have been reduced due to the presence of Zebra chip (ZC). The use of anti-aphid nets is becoming a popular approach to provide physical protection from insects that transmit ZC. The aim of this work was to evaluate the physicochemical characteristics of potato tubers and their chips, produced with and without the protection of an anti-aphid net in Metepec State of Mexico. Five genotypes were studied (Fianna, Nau, 5-10, 8-65, 99-39). The anti-aphid net reduced 34.5 % the photosynthetic active radiation and consequently the starch accumulation and chips yield. ZC infected the non-covered plants and their tubers had more browning and reducing sugars (19.67 g kg-1) than covered tubers (4.77 g kg-1), but they had similar contents of total phenolic compounds. Potato crop protection with an anti-aphid net may be an alternative to produce tubers with quality for fresh consumption and chip processing.
