STK102

Engineering solutions in STK102 breeding

The selection product from Soytek S.R.L. under the index STK102 is the result of the work of breeder Stelian Fuia, aimed at creating a stable sunflower hybrid with a focus on phytosanitary resistance. The development is based on a specific genetic base that provides resistance to pathogens under intensive farming conditions.

Phytopathological profile and protection

The main technical advantage of the hybrid is its pronounced tolerance to a complex of diseases. The plant's genetic architecture is tuned to effectively counteract downy mildew (peronosporosis), which is critical for preventing early lodging and the loss of photosynthetic area. In addition, the hybrid has high resistance to powdery mildew, which allows for reduced fungicide load on crops during critical growth stages.

Morphological indicators and yield potential

• Seed type: Medium-sized, features a classic black color, indicating a high oil content in the kernel.
• Basket architecture: Has a slightly convex shape on the seed side, which promotes uniform ripening and high-quality threshing without significant harvest losses.
• Basket size: Belongs to the large category, providing a high volume of potential seed yield at optimal plant density.

Due to the selection by Soytek S.R.L., STK102 demonstrates high plasticity in various soil and climatic conditions while maintaining the declared resistance characteristics. A technologically sound choice for farmers focused on reducing the risks of infectious sunflower diseases without compromising the volume of commercial grain.
