Rozanna potato — an early-maturing, table-type variety of French origin, intended for cultivation in the Central, Central Chernozem, and North Caucasus regions. The maturation period is 65-75 days, with the first harvest possible as early as day 45 after emergence of sprouts. The plant is of medium height, semi-erect or sprawling, with large green leaves and purple-red flowers. Tubers are elongated-oval, with smooth red skin and light-yellow flesh, weighing from 87 to 147 grams. The number of tubers per plant varies from 8 to 11.
The variety has high and stable yield: marketable yield ranges from 155 to 296 centners per hectare, with a maximum of 398 centners. Yield on day 45 after sprouts emerges at the level of top standards, and by day 55 it exceeds them significantly. Starch content in tubers is 11.0–13.2%, ensuring good taste and versatility in culinary applications. Rozanna potato is suitable for making soups, salads, and frying; it does not break down during cooking and can be used for drying and further processing.
The variety exhibits high resistance to diseases, including potato blight and golden nematode, as well as good drought tolerance and does not require special soil conditions. Tubers have a marketability of 76–96% and storability of 88%, making Rozanna a profitable choice for both farmers and gardeners. Due to its combination of early maturity, high yield, excellent taste, and disease resistance, this variety has maintained popularity over many years.
