Sunflower Larissa

Genetic Architecture and Protection

The “Larissa” hybrid from the Moldovan company Quality Crops Agro S.R.L. is a classic simple hybrid designed to deliver stable yields under intensive farming conditions. The breeding focus for this hybrid is placed on the balance between high oil content (50-55%) and fundamental phytosanitary safety. With a plant height ranging from 150 to 180 cm, it possesses robust vegetative mass, allowing for efficient utilization of solar energy and moisture during the 120-130 day growing season.

Phytopathological Resistance

The key advantage of “Larissa” is its genetic barrier against dangerous fungal infections. The hybrid demonstrates high resistance to:

• Downy mildew (Peronospora), which is critical for preventing seedling mortality;
• Alternaria blight, which affects the leaf apparatus during the seed-filling phase;
• Phomopsis, which degrades the stem system.

In practice, this translates to reduced pesticide input: farmers can minimize fungicide applications while maintaining a healthy photosynthetic apparatus right up to maturity.

Morphology and Yield Potential

The hybrid's seeds are medium-sized with a distinct grey-striped pattern. The flattened shape of the head ensures optimal seed distribution and uniform drying, minimizing the risk of crop loss under adverse weather conditions prior to harvest. The combination of a medium growth period with a high oil accumulation density makes this hybrid an economically viable solution for farms focused on producing high-quality processing raw materials.
