The hybrid belongs to the earlier maturity groups. It is characterized by high tolerance to Phomopsis, as well as field resistance to Macrophomina and Phoma.
It is distinguished by drought tolerance. Under water deficit conditions, it maintains a high rate of photosynthesis and quantum yield of photosynthesis due to an increased content of soluble proteins, in particular Rubisco protein, in the leaves.
Oilseed usage direction. During the 1990s and 2000s, the hybrid was actively used as an object for studying plant physiology and breeding for resistance to biotic and abiotic stresses.
