Simple interline hybrid of oleic type.

Originator - Plant Production Institute nd. a V.Ya. Yuryev of NAAS and Selection and Genetics Institute - National Center for Seed and Variety Study of NAAS (Odessa).

It has been entered in the Plant Variety Register of Ukraine for growing in steppe and forest-steppe zones of Ukraine since 2013.

Approbation characteristics: plant height - 175 cm; slightly convex calathid up to 22 cm in diameter; huskness - 22%; incrustation – 99.5%; mass of 1,000 seeds - up to 63 g; oil content in seeds – up to 50.9%; oil yield is 1,769 kg/ha, which exceeds the standard by 83 kg/ha.

Biological features: ripeness group – early-maturing, growing season – 104 days. Lodging resistance- high. Shedding resistance - high. Downy mildew resistance - high. Broomrape resistance - high. Sufficiently drought-resistant and root rot resistant.

Economic features: The yield capacity of the sort Oreol exceeds the standard by 0.22 t/ha in the competitive variety trial. The hybrid crop potential – 4.1 t/ha, the female parent plant crop potential – up to 2.1 t/ha. Oleic acid glyceride content in oil – 80.0% of the total acid content.

Peculiarities of cultivation technology: recommended density – 50,000 plants per hectare. To provide high oleic acid content it is necessary to grow this hybrid at the distance of 1,500 m from hybrids of linoleic type. Preparation of soil and seeds for sowing is conventional.

Peculiarities of seed industry: in the hybridization areas the parent lines are sown simultaneously. No desiccation is needed if sowing is early (before May 5). The recommended sowing pattern - 12:4, 6:2, 10:2. The yield capacity of the female parent line is up to 2.1 t/ha. The yield of certified seeds is 65-70%. The optimal density by the harvest term is 55,000 plants per hectare. It is possible to sow with other female parent lines of the following hybrids: Sonagro, Raut, Maximus, Zorepad, Dariy and others for which the pollen fertility restorer is line Х 526 В.
