TRUVOR

 

 

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 2012.


Approbation characteristics: plant height - 165 cm; markedly convex calathid up to 20 cm in diameter; huskness - 22%; incrustation – 99.8%; mass of 1,000 seeds - up to 69 g; oil content in seeds – up to 49.0%; oil yield is 1,798 kg/ha, which exceeds the standard by 212 kg/ha.
Biological features: ripeness group - early maturing, growing season - 101 days. Lodging resistance- high. Shedding resistance - high. Downy mildew resistance - high. Broomrape resistance - high. Sufficiently drought-resistant, root rot resistant.


Economic features: The yield capacity of the sort Truvor exceeds the standard by 0.31 t/ha in the competitive variety trial. The hybrid crop potential – 4.0 t/ha, the female parent plant crop potential – up to 1.9 t/ha. Stearic acid glyceride content in oil – 8.4% of the total acid content.
Peculiarities of cultivation technology: recommended density by the harvest term – 55,000 plants per hectare. Seeds must be pretreated with Cruiser 350-Fs at the dose of 6 L/t and Kolfugo Super at the dose of 2 L/t. Sowing is performed in preheated to 10˚C soil with the depth of seed placement of 6 cm. Soil compaction by seed rolling is obligatory.

 

Peculiarities of seed industry: the preparation of seeds includes pretreatment of the parent line seeds with Cruiser 350-Fs, in addition to it the female parent seeds should be pretreated with Apronom. Sowing is performed in two phases: first the female parent is sown, then after appearance of cotyledons the pollen fertility restorer is sown. Weed protection: use Harness at the dose of 2.8 L/ha with working-in before sowing, after coming-up use Fusilade Forte against gramineous weeds.


Harvesting is performed when the seed moisture content is 12%; seeds should be dried until the moisture content is 7%. The yield of certified seeds is 60 - 70%.
