The Soybean variety Yuzanka is an early-maturing, high-yielding variety developed at FGБNU «Volzhsky SSI» and adapted to the contrasting natural and climatic conditions of the forest-steppe of the Samara Volga region. It has been included in the State Register of Breeding Achievements of the Russian Federation for the Middle Volga region and recommended for cultivation in the Samara region. The variety's vegetative period lasts about 102 days, classifying it as an early-maturing group, with an early flowering time. The plants are of indeterminate growth type, low-growing, with a height of about 57 cm and a lower pod attachment height of 16.6 cm.
