Originator - Plant Production Institute nd. a V.Ya. Yuryev of NAAS.

Hybrid type - three-way cross.

Entered in the Plant Variety Register of Ukraine in 2002. Zones recommended for growing: forest-steppe, woodlands.

Approbation characteristics. Variety - tooth-like (ssp.indentata). The plant height is 230-250 cm. The height of earcorn attachment is 95-100 cm. The number of leaves is 14-15. The earcorn length is 20-22 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 280-290 g.

Biological features. Ripeness group – early-ripening, FAO 190. The duration of «seedling-ripening» period is 95-100 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 10.0-10.5 t/ha. The recommended density by the harvest term is 63,000-65,000 plants per hectare in forest-steppe, 65,000-68,000 plants per hectare in woodlands. The harvest moisture is 19-20%. The potential green mass yield is 43-45 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 98-99%. The optimal planting system of parent lines in hybridization areas is 6:2; 12:4. Parent lines sowing in hybridization areas is performed within the same term and at the same depth. The seed yield under favourable conditions is 1.5-2.0 t/ha.
