Hybrid type - double-cross interline.

Entered in the Plant Variety Registers of the RF and Ukraine in 2008. Zones recommended for growing: forest-steppe, woodlands and the 5th region of the Russian Federation.

Approbation characteristics. Variety – flinty, tooth-like (ssp.semidentata). The plant height is 280-290 cm. The height of earcorn attachment is 97-102 cm. The number of leaves is 16-17. The earcorn length is 24-26 cm. The number of seed rows per ear is 16-18. The grain yield is 82-84%. The ear shank is red. Mass of 1,000 seeds is 300-305 g.

Biological features. Ripeness group: middle-early, FAO 270. 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 is high. Resistance to stem rots is high. Resistance to corn borer is high.

Economic features. The potential grain yield capacity is 10.0-10.3 t/ha. The recommended density by the harvest term is 60,000-65,000 plants per hectare in forest-steppe and 65,000-70,000 plants per hectare in woodlands. Harvest moisture is 22-25%. The potential green mass yield is 50.0-51.0 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.
