Resistance to loose smut is high. Resistance to boil smut is high. Resistance to stem rot is high. Resistance to corn borer is high.

The potential grain yield is 11.0-11.5 t/ha. The recommended harvest density: 60,000-63,000 plants/ha in the Steppe. The harvest water content is 19-20%. The protein content in grain is 10%. The starch content is 74%.

Seed production peculiarities. The seed production of this hybrid is based on M-type sterility according to the complete restoration algorithm, without removing panicles. The optimal sowing arrangement for parents in hybridization plots is 12:4 or 6:2. Hybridization plots require intensive farming, weed control and nutrition.

When grown by intensive farming techniques, the seed yield amounts to ≥4.5 t/ha.
