Sunflower Praveks

The Genetic Architecture of the «Praveks» Hybrid

«Praveks» from «Henezis Sidz» is a selection product focused on stable production under intensive farming conditions. Originators Myroslav and Iaroslav Parii have embedded potential into this simple hybrid that fully unfolds within a 105–110 day vegetation period. The mid-early ripening period allows for effective harvest planning, avoiding waterlogging and critical weather factors in late summer.

Agrotechnical Advantages and Resistance

The key technical advantage of «Praveks» is its full compatibility with the Clearfield technology. This gives farmers a tool to control a wide spectrum of weeds without mechanical cultivation, which is critical for preserving soil structure and moisture retention. The hybrid's genetic resistance covers key sunflower pathogens:

• Rot complex: an effective barrier against white and gray rot, which affect many hybrids in high-moisture conditions.
• Pathogen protection: selection is focused on blocking the development of downy mildew (peronosporosis), phomopsis, and phoma, minimizing fungicide application costs.

Morphological Indicators and Oil Content

A stem height of 160–180 cm characterizes the hybrid as a crop with high technology readiness. This height ensures ease of harvesting and sufficient leaf surface area for photosynthesis. The medium-sized head, combined with black seeds, is a classic indicator for high-quality raw material that is easy to clean and dry. With an oil content of 48–50 %, «Praveks» ensures high economic efficiency, allowing for a worthy oil yield per hectare.

Ukrainian selection by «Henezis Sidz» in the form of this hybrid is a balanced choice for those betting on herbicide tolerance and predictable yields in standard Ukrainian climatic zones.
