Sunflower LS 45 K 2

Genetic Architecture of LS 45 K 2

The breeding strategy of NPO "Semenovodstvo Kubani" for the LS 45 K 2 hybrid focuses on a balance between oil content and phytosanitary resilience. With a vegetation period of 110-120 days, this mid-early hybrid allows for efficient utilization of soil moisture, successfully avoiding critical temperature spikes during the seed-filling phase.

Phytopathological Shield

The primary advantage of this sunflower hybrid is its comprehensive resistance to yield-limiting pathogens. Genetic control over downy mildew prevents premature crop failure, while resistance to phomopsis and phoma protects the stem from vascular system degradation. Practically, this ensures stem integrity until harvest, effectively minimizing losses from lodging.

• Oil Content: An oil concentration of 45-50% is maintained through the hybrid's metabolic stability, even under moderate environmental stress.
• Resistance to Rots: The hybrid displays high resistance to white and grey rots, which is critical during periods of high humidity before harvest.
• Powdery Mildew Defense: Integrated immunity helps reduce the need for intensive fungicide applications, optimizing costs per hectare.

Technically, LS 45 K 2 is designed for intensive farming systems, where yield potential is maximized through precise mineral nutrition and optimal plant density management. A stable growth habit and a well-filled head make it a reliable tool in crop rotation for producers focused on high-quality commercial grain.
