Amur

The potato variety Amur belongs to the mid-early maturing group with a tuber maturation period of 65 to 75 days. This variety is characterized by high yield, averaging around 250 centners per hectare, with maximum yields reaching 369 centners per hectare under favorable conditions. Tubers have a neat oval shape with small eyes, reddish-brown skin, and light-yellow flesh. The average weight of marketable tubers ranges from 97 to 128 grams, and starch content varies from 12.6% to 15.7%, ensuring good taste and excellent culinary qualities. Marketable tuber percentage is high — from 76% to 93%, and storability reaches 94%, allowing for long-term storage without quality loss.

Plants of the Amur variety have medium height and intermediate growth type with semi-erect form. Leaves are medium-sized, color ranges from green to dark green, and flower corolla is medium-sized with intense anthocyanin coloring on the inner side. The variety is resistant to several diseases, including potato blight, mosaic virus, and leaf curl. However, it is susceptible to golden potato cyst nematode and moderately resistant to phytophthora, requiring protective measures to maintain plant health.

To protect the Amur potato from diseases, it is recommended to use combined fungicides with both contact and systemic action. These agents provide reliable protection against phytophthora and other fungal diseases by penetrating plant tissues and protecting both vegetative and generative parts. Application of fungicides not only prevents disease development at early stages but also preserves tuber quality during storage, which is especially important for maintaining high marketability and storability of the crop.
