Sylvana is a medium-early table potato variety with a vegetation period of 110 to 125 days. The plant is tall, intermediate in type, with a semi-upright bush form and medium-sized light-green leaves. Tubers are predominantly round-oval, with smooth yellow skin and light-yellow flesh, weighing 90 to 148 grams. Eyes are shallow, facilitating peeling. Starch content ranges from 13.6% to 15.3%, providing good flavor and slight fluffiness when boiled, making it suitable for soups, mashed potatoes, and stews.
The variety has high commercial yield, reaching 165 to 375 centners per hectare, with peak yields up to 448 centners in certain regions. Each plant produces 9 to 12 tubers, contributing to stable and high yields. Tubers have a commercial grade of 84–96%, and storage durability reaches 91%, ensuring good product preservation during storage.
Sylvana exhibits good resistance to several diseases, including potato late blight, golden potato cyst nematode, powdery mildew, blackleg, common scab, and dry rot. It is moderately susceptible to tuber blight and viral diseases. Due to its drought tolerance and adaptability to various climatic conditions, Sylvana is a reliable choice for cultivation in Central and Volga-Vyatka regions of Russia.
