Special condition of environment and droughty are the reason limitation of product area in Iran. Factories strongly need high quality and quantity potatoes. Introduction of new potato with high potential can improve income of farmers. In order to introduce new potato cultivars with high yield this experiment conducted in seven locations for two years. Experiment design was Random Complete Block Design (RCBD) with three replications. Tubers were planted on two rows with 6 meters length. Distance between row and plants on the row was 75 and 25 Cm, respectively. Plants were harvested except one plant from first and end of each row. Natasha, Caruso, Andante, Verona, Opal, Arcona, Miranda, Olympia, BSS-296 (TPS), Agria and Sante was planted as treat. The results indicated that varieties differed for dry matter and starch. Amount of dry matter and starch for Opal, BSS-296 (TPS) and Caruso was more than others respectively. Combine analysis variance for location and year showed significant different among location for marketable yield and number of stem i.e., varieties had different response at different location for features mention above and environment affected on them. Opal and Miranda had preference over others varieties based on total quality and quantity properties and were introduced for spring sowing as moderate and early maturity varieties, respectively. Opal is apprpriate for processing and could be used for French fries. BSS-296 (TPS) had an acceptable uniformity for most traits. Yield and dry matter of BSS-296 (TPS) were superior over check varieties ( Agria and sante ). Therefore, it could be utility as a method for production of chipper ware potato with suitable quality at special condition.
