Limit sunflower, Kharkiv region.

Sunflower hybrid F1 "Limit".

Features of the hybrid: resistant to herbicides of the imidazoline group (Eurolighting, Euro-Lang, Euro-Land) - resistant to all races of Zarazikha, high resistance to air and soil drought, high bunker weight of seeds, tolerant to thickening, high oil content, up to 54% in 2017!

The method of creating a hybrid: by means of interlineal hybridizations using the genetic system of CMS (cytoplasmic male sterility) with full restoration of fertilityпылцы.

Entered into the register of plants of Ukraine for growing in the Steppe and Forest Steppe zones in 2014.

Approval signs: Used forproduction of oil. The height of the plants is 160-180 cm. The stem is of medium thickness. The number of leaves on the stem is 27-29 pcs. The leaf plate is medium. The beginning of flowering is early. The basket is medium thin and convex. A seed of medium size. Weight of 1000 seeds - 65-70 gr.

Biological signs: A simple early-maturing hybrid. The duration of the growing season is 105-110 days. It differs in super-drought resistance, and has genetically determined soil resistance to the most virulent 6th race of the disease and to the 730th race of powdery mildew.

Economic characteristics: Average yield in the Steppe zone is 29 t/ha, in the Forest Steppe zone 38 t/ha. Hybrid vysokomaslichnyj — the oiliness of the seeds is 50-52%. Optimum yield is achieved when the density of standing plants for harvesting in the Steppes is 60,000. plants per 1 ha, in Lesostepa - 65 thousand plants per 1 ha.

The hybrid is resistant to postemergence herbicides of the imidazole group (Eurolighting, Euro-Lang, Euro-Land). One treatment with theseherbicides during the entire vegetation period, it allows to destroy the majority of malicious cereal and dicotyledonous weeds (ambrosia, thistle, wheatgrass and others). These herbicides also destroy the infection even before the emergence of its shoots, when treated with the herbicide in the phase of sunflower development from two to six pairs of true leaves.

In the areas of hybridization, spatial isolation was observed, timely and qualitative weeding and phytosanitary cleaning of maternal and paternal lines were carried out in order to preserve the biological purity and uniformity of the hybrid. The post-harvest dormancy period of seeds was 2.0 months. The seeds are calibrated, incrusted, etched and ready for sowing.
