Hybrid type - double-cross interline.
Entered in the Plant Variety Register of Ukraine in 2008. Zones recommended for growing: forest-steppe, woodlands.

Approbation characteristics. Variety flinty, tooth-like (ssp.semidentata). The plant height is 230-260 cm. The height of earcorn attachment is 92-97 cm. The number of leaves is 14-15. The earcorn length is 22-24 cm. The number of seed rows per ear is 14-16. The grain yield is 84-85%. The ear shank is red. Mass of 1,000 seeds is 270-275 g.

Biological features. Ripeness group – early-ripening FAO 190. The duration of «seedling-ripening» period is 95-102 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 is high. Resistance to stem rots is high. Resistance to corn borer is moderate.

Economic features. The potential grain yield capacity is 10.0-11.0 t/ha. The recommended density by the harvest term is 60,000-65,000 plants per hectare in forest-steppe, 65,000-68,000 plants per hectare in woodlands. The harvest moisture is 18-22%. The potential green mass yield is 43.0 – 46.0 t/ha. Solids content in green mass is 32-33%. Protein content in grain is 9.8-10.2%. Starch content is 74,8%.

Hybrid seed breeding is based on sterility of M-type. Female sterility is 99-100%. The optimal planting system of parent lines in hybridization areas is 12:4, but 10:2 is also possible. Sowing of parent lines in hybridization areas is performed within the same term and at the same depth. The seed yield under favourable conditions is 2.5-2.8 t/ha.
