This experiment was conducted to evaluate the agronomic and qualitative traits of potato cultivars in winter season in Ardabil region during the years 2016-2018. Five potato cultivars (Agria, Savalan, Javid, Milva and Jelly) were evaluated according to Randomized Complete Block Design with three replications. Results of analysis of combined variance showed that are significant differences between years in plant height, tuber number per plant, tuber yield and water use efficiency; between cultivars in plant height, tuber number and weight per plant, tuber yield and water use efficiency and between cultivars × years interaction in plant height, tuber number and weight per plant, tuber yield, dry matter percent and water use efficiency. In winter cultivation (planting date of 20th February), Agria and Savalan cultivars had the highest tuber yield and water use efficiency. The average of tuber yield were obtained in winter cultivation (planting date of 20th February) about 28.71 ton per hectare. The difference in tuber yield in spring sowing to winter sowing about 10.065 ton per hectare. In the winter sowing were done about 4551 cubic meters per hectare. The difference of water consumption winter cultivation (planting date of 20th February) with spring sowing (planting date of 1 May) 9663 cubic meters per hectare.
