BOREI

 

Simple interline hybrid.

 
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 2011, in the Register of Breeding Achievements of the Russian Federation since 2011 in the 5th region.


Approbation characteristics: plant height - 160 cm, convex calathid up to 20 cm in diameter; huskness - 18%; incrustation – 99.6%; mass of 1,000 seeds - up to 55 g; oil content in seeds – up to 51%; oil yield is 2,156 kg/ha, which exceeds the standard by 570 kg/ha.
Biological features: ripeness group - early maturing, growing season - 102 days. Lodging resistance- high. Shedding resistance - high. Downy mildew resistance - high. Broomrape resistance - high.


Economic features: The yield capacity of the sort Borei exceeds the standard by 0.64 t/ha in the competitive variety trial. The hybrid crop potential – 4.3 t/ha, the female parent plant crop potential – up to 2.2 t/ha. Stearic acid glyceride content in oil – 5.93% of the total acid content.
Peculiarities of cultivation technology: recommended density by the harvest term – 55,000 plants per hectare.
Peculiarities of seed industry: the yield of certified seeds is 60 - 70%. In the hybridization areas the parent line seeds are sown in two phases: the male parent is sown after appearance of the first pair of true leaves in the female parent line. The yield capacity of the female parent varies from 1.4 to 2.2 t/ha. The density of the parent plants in hybridization areas is 55,000-60,000 /ha. A delay of sowing may require desiccation
