Kleopatra

Genetic Potential and Phytosanitary Defense

The «Cleopatra» sunflower hybrid from the «Solnechnaya Strana» brand is a breeding product focused on early maturity and high oil content in intensive farming conditions. The key feature of this hybrid is its compressed vegetation period (80–90 days), which shifts the grain filling phase away from peak summer heat stress.

Morphological Parameters

The hybrid plants reach a height of 170–180 cm. This compactness is achieved through optimized distribution of plastic substances: energy is directed toward the formation of a high-quality head rather than excessive vegetative mass. The optimal stem height facilitates smoother combine harvesting and minimizes mechanical losses.

Protective Mechanisms

The genetic code of «Cleopatra» includes multi-level immunity, which is critical for yield preservation under adverse phytosanitary conditions. The originators (O. A. Belyaeva, I. A. Koshkarev, R. S. Nazarov) focused on the following threats:

• Fundamental resistance to downy mildew and bacteriosis: the hybrid reduces the need for heavy fungicide application during early growth stages.
• Barriers against fungal pathogens: high resistance levels against alternaria, sclerotinia, phomopsis, root rots, and black leg. This allows for seeding in rotations with minimum tillage, where the infection load is typically higher.

An oil content of 45–50% makes «Cleopatra» an economically attractive option for processing facilities, ensuring a high yield of final products per ton of grain. This technological solution from «Solnechnaya Strana» provides farmers with predictable results within a short time frame.
