Sunflower RT 21

Technological potential of RT 21: genetic foundation

The RT 21 hybrid from the RAT brand is designed for intensive farming, where profitability is driven by effective weed management. The physiology of this hybrid is built on Clearfield (Euro-Lightning) technology, allowing growers to eliminate persistent weeds and broomrape without stressing the crop.

Engineering and selection features

As a simple hybrid, RT 21 provides a high level of crop uniformity. This is a critical technical advantage for synchronized head maturation, which simplifies combine harvester calibration during the harvesting stage. The primary features established by RAT’s selection focus on maintaining stability in various climatic conditions:

• Herbicide resistance: The genetic trait allows for the use of imidazolinone-based herbicides. This eliminates the competitive pressure between the crop and weeds for moisture and nutrients during the plant's most critical growth phases.
• Plant structure: The simple hybrid architecture ensures a predictable response to fertilizer applications. The root system and stem morphology are optimized for efficient nutrient transport, minimizing yield loss during seed filling.

The practical value of implementing RT 21 lies in harvest predictability. Adaptability to the Euro-Lightning production system minimizes risks associated with early-season weed infestations, positioning this seed as a primary tool for achieving a clean field with minimal mechanical weeding costs.
