Increasing concerns have been verified with regard to the quality factor of potato tubers and their correct form of use and consumption. The purpose of this research was to determine the technological quality of potato tuber cultivars and identify the best forms of use and consumption. A completely randomized experimental design was adopted with 18 treatments represented by cultivars Agata, Apuã (IAC-5977), Aracy (IAC-2), IAC Aracy Ruiva, Asterix, Bintje, Dali, Clone IAC-6090, Itararé (IAC-5986), Laguna, Remarka, Liseta, Mondial, Novita, Oscar, Picasso, Santana, and Solide, with four replications. Specific gravity showed a positive correlation with starch content, texture, pulp pH, and soluble solids, and was negatively correlated with reducing sugars. The technological characteristics represented by specific gravity, dry matter content, texture, starch content, reducing sugars, pulp pH, titrable acidity, and soluble solids are influenced by genotype or cultivar. Cultivars Oscar, Itararé, IAC Aracy Ruiva, Clone IAC-6090, Aracy, Solide, Asterix, Santana, and Laguna were outstanding with best characteristics for frying, mashing and roasting. Mondial, Picasso, Novita, Dali, and Agata are appropriate for boiling, and more specifically for salads. In turn, potato cultivars Apuã, Remarka, Bintje, and Liseta are suitable for mashing and for roasting.Downloads
