Hybrid type - three-way cross.

Entered in the Plant Variety Register of Ukraine in 2003. Zones recommended for growing: forest-steppe, woodlands.

Approbation characteristics. Variety - flinty, tooth-like (ssp.semidentata). The plant height is 280-290 cm. The height of earcorn attachment is 95-100 cm. The number of leaves is 16-17. The earcorn length is 25-27 cm. The number of seed rows per ear is 14-16. The grain yield is 83-85%. The ear shank is red. Mass of 1,000 seeds is 270-280 g.

Biological features. Ripeness group: middle-early, FAO 250. The duration of «seedling-ripening» period is 108-110 days. The initial growth is fast. Cold tolerance is high. Drought resistance is high. Lodging resistance is high. Resistance to ear necking is high. Resistance to loose smut is high. Resistance to boil smut to high. Resistance to stem rots is high. Resistance to corn borer is high.
Economic features. The potential grain yield capacity is 9.70-10.3 t/ha. The recommended density by the harvest term is 60,000-62,000 plants per hectare in forest-steppe and 65,000-67,000 plants per hectare in woodlands. The harvest moisture is 24-25%. The potential green mass yield capacity is 48.0-50.0 t/ha. Solids content in green mass is 32-34%. Protein content in grain is 10.2%. Starch content is 72.0%.

Hybrid seed breeding is based on sterility of M-type by full recovery pattern, without cutting off panicles. Female sterility is 99-100%. The optimal planting system of parent lines in hybridization areas is 12:4; 6:2. The yield of certified seeds provided high agricultural technology amounts to 2.0-2.5 t/ha.
