The objective of this work was to compare four varieties of potato (S. andigenum Hawkes, S. curtilobum Juz et Buk, S. juzepczukii Buk, S. stenotomum Just et Buk) in terms of phenology and yield under agroecological conditions of the Altiplano region. Peru. For this, phenological parameters were evaluated (description of the tuber, plant, leaf, flower, berries, flowering intensity and vegetative period) and productive (yield and number of tubers). The sample consists of 40 plants selected at random, which were planted in sandy loam soil, under traditional agronomic management and gravity irrigation. It was determined that the Ssp. andigenum Hawkes has the highest production (number and weight) in relation to the varieties studied. The vegetative period lasted between 169 to 183 days. It is concluded that the varieties studied are species of semi-late phenological cycle.
