Hybrid type - single-cross interline.


Entered in the Plant Variety Register of Ukraine in 2012. Zones recommended for growing: steppe, forest-steppe, woodlands.
Approbation characteristics. Variety - tooth-like (ssp. indentata). The plant height is 240-250 cm. The height of earcorn attachment is 90-95 cm. The number of leaves is 16-17. The earcorn length is 23-24 cm. The number of seed rows per ear is 16-18. The grain yield is 84-85%. The ear shank is red. Mass of 1,000 seeds is 330-340 g.


Biological features. Ripeness group: middle-early, FAO 260. The duration of «seedling-ripening» period is 106-110 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 10.5-11.0 t/ha. The recommended density by the harvest term is 55,000-62,000 plants per hectare in steppe, 60,000-65,000 plants per hectare in forest-steppe and 65,000-67,000 plants per hectare in woodlands. The harvest moisture is 22-23%. Solids content in green mass is 32-34%. Protein content in grain is 9.8%. Starch content is 76.5%.
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 1.0-1.2 t/ha.
