REGISTR

 

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 2013.


Approbation characteristics: plant height - 170 cm; slightly convex calathid up to 21 cm in diameter; huskness - 19%; incrustation – 99.9%; mass of 1,000 seeds - up to 55 g; oil content in seeds – up to 50.8%; oil yield is 1,760 kg/ha, which exceeds the standard by 257 kg/ha.
Biological features: ripeness group - early maturing, growing season - 97 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 Registr exceeds the standard by 0.38 t/ha in the competitive variety trial. The hybrid crop potential – 3.9 t/ha, the female parent plant crop potential – up to 1.9 t/ha.


Peculiarities of cultivation technology: recommended density – 50,000 plants per hectare. Seeds must be treated with pesticides and fungicides. Depth of seed placement is 6 cm. Roller compaction is required upon moisture deficit.
Peculiarities of seed industry: in the hybridization areas the parent lines are sown simultaneously. The female parent plants must not be left to stand too long in the hybridization areas. Seeds may germinate in calathids as a result of increased moisture and high temperature during the period of the female parent complete maturing. The yield of certified seeds is 60-65%.
