Harves CL

Technological potential of KWS Harves KL hybrid

The productivity of KWS Harves KL sunflower is based on genetically determined adaptability to intensive farming technologies. As a simple hybrid, it demonstrates uniform emergence and synchronized ripening, which is critical for minimizing losses during harvesting.

Phytosanitary barrier

The key engineering solution in this model's breeding is a multi-level pathogen protection system. The hybrid's genetic code contains pronounced resistance mechanisms to major sunflower diseases, allowing for reduced fungicide application:

• Sclerotinia: High tolerance to head and stalk rot, which is particularly relevant during periods of high humidity in the second half of the growing season.
• Downy mildew (Peronospora): Resistance to all known pathogen races, eliminating the risk of premature crop loss.
• Phomopsis and Phoma: A strong stem structure and resistance to the destructive effects of fungal infections preserve yield potential until harvest time.

Production efficiency

The 105–110 day vegetation period classifies Harves KL as a mid-early hybrid. This developmental dynamic allows for the optimal utilization of accumulated active temperatures across various climatic zones. Integration into the Clearfield system opens wide possibilities for weed control. The use of imidazolinones on these crops allows for the effective suppression of persistent weeds like Canada thistle or ragweed without causing stress to the sunflower itself. German breeding by KWS ensures stable realization of potential even under varying soil and climatic conditions.
