TAIM

 

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 - 98 days. Lodging resistance- high. Shedding resistance - high. Downy mildew resistance - high. Broomrape resistance - high. Drought-resistant, sufficiently root rot resistant.


Economic features: The yield capacity of the sort Taim 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 – 6.4% of the total acid content.
Peculiarities of cultivation technology: recommended density by the harvest term – 55,000 plants per hectare. Sowing is performed at the soil temperature of 10˚C at the depth of 10 cm. 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. No desiccation of sunflower crops is needed if sowing is done before May 15.


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 simultaneously.
Harvesting is performed when the seed moisture content is 12%; seeds should be promptly peeled and dried until the moisture content is 7-8%. The yield of certified seeds is 60 - 70%.
