Hybrid type - double-cross interline.


Entered in the Plant Variety Register of Ukraine in 2010. Zones recommended for growing: steppe, forest-steppe.


Approbation characteristics. Variety - tooth-like (ssp. indentata). The plant height is 220-230 cm. The height of earcorn attachment is 93-95 cm. The number of leaves is 16. The earcorn length is 26-27 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 320-330 g.


Biological features. Ripeness group: mid-ripening, FAO – 310. The duration of «seedling-ripening» period is 115-117 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 13.5-14.0 t/ha. The recommended density by the harvest term is 55,000-60,000 plants per hectare. The harvest moisture is 24-25%. The potential green mass yield capacity is 55.0-60.0 t/ha. Solids content in green mass is 32-33%. Protein content in grain is 9.9-10.2%. Starch content is 74.8%.


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 and 10:2. Seed-breeding plots require high agricultural technology, struggle with weeds and optimal feeding conditions. The seed yield capacity under favourable conditions is 2.8-3.0 t/ha.
