Simple interline hybrid of palmitic type.
Originator - Plant Production Institute nd. a V.Ya. Yuryev of NAAS.


It has been entered in the Plant Variety Register of Ukraine for growing in steppe and forest-steppe zones of Ukraine since 2012.
Approbation characteristics: plant height - 160 cm, slightly convex calathid up to 20 cm in diameter; huskness - 21%; incrustation – 99.6%; mass of 1,000 seeds - up to 55 g; oil content in seeds – up to 51%; oil yield is 1781 kg/ha, which exceeds the standard by 197 kg/ha.


Biological features: ripeness group - early maturing, growing season - 98 days. Lodging resistance- high. Shedding resistance - high. Downy mildew resistance - high. Broomrape resistance - high. Sufficiently drought-resistant. No root rot resistance.


Economic features: The yield capacity of the sort Rubikon exceeds the standard by 0.25 t/ha in the competitive variety trial. The hybrid crop potential – 3.9 t/ha, the female parent plant crop potential – up to 1.3 t/ha. Palmitic acid glyceride content in oil – 16.0% of the total acid content.
Peculiarities of cultivation technology: recommended density by the harvest term – 55,000 plants per hectare. Sowing should be performed after preheating of the upper layer of soil (10 cm) to 10˚C. Seeds must be pretreated with soil pest killers. No desiccation is needed.


Peculiarities of seed cultivation technology in hybridization areas: recommended density of parent plants by the harvest term 55,000 per hectare.


The parent lines are sown in two phases: first the pollen fertility restorer is sown, then after appearance of the first leaf pair the female parent is sown.


Be sure to provide with hives in the amount of 3 honey-bee colonies per 1 ha of crops. The yield of certified seeds is 60 - 65%.
