Ordinary bean of the Cupava variety is a new medium-maturing grain-purpose variety created by individual selection from a hybrid population. Plants of a determinate growth type reach a height of 45-60 cm and have medium branching with 2-4 shoots. A distinguishing feature of the variety are large, smooth, and shiny seeds of wine-red color with a thin skin. During the growing season, which lasts an average of 87 days, 10 to 35 pods are formed on the plant, averaging 18 pods. The variety matures 5 days later than the standard and is characterized by lodging resistance when planted with wide rows, which allows efficient use of direct combine harvesting during crop collection.
Cupava demonstrates high yield — the average indicator is 24.4 c/ha, which is 5 c/ha higher than the standard, and the maximum yield reached 28.6 c/ha. Under conditions of the Omsk region, the yield can reach 30.5-35.0 c/ha. Plants have a bushy medium-height shape, and the mass of 1000 seeds varies within 330-340 g. Protein content in seeds is 22.1-23.7%, which makes the bean not only nutritious but also beneficial for consumption.
The Cupava variety is recommended for cultivation in various regions, including the Omsk region, due to its adaptability and stable productivity. Despite weak resistance to anthracnose, the variety performs well in agroecosystems and is suitable for mechanized harvesting. Large and high-quality beans of the Cupava variety are suitable for a wide range of culinary and industrial purposes, making this variety attractive for farmers and agrarians seeking high and quality yields.
