D 37

Technical Potential and Selection Profile of D 37

Developed by breeder Nikolay Savelyevich Cheban, the D 37 sunflower hybrid is a balanced tool for farms focused on stable oil content with moderate vegetation periods. The hybrid is built on a focus on phytosanitary resistance and morphology that optimizes harvesting processes.

Biological Protection: Pathogen Resistance

A key yield factor in high infection environments is the hybrid's resistance to major fungal diseases. The genetic code of D 37 includes effective resistance mechanisms against sclerotinia, phomopsis, and phoma. For agronomists, this means lower expenditure on fungicide applications and minimized biomass losses during high-humidity periods when the risk of head and stem rot becomes critical.

Morphology and Technical Performance

• Vegetation Period: 100-110 days. The hybrid belongs to the early-maturing group, allowing producers to avoid critical temperature peaks and clear fields for winter crop sowing.
• Plant Habit: A height of 170-180 cm ensures optimal nutrient distribution and efficiency during mechanical harvesting.
• Head Structure: The convex, medium-sized head shape promotes uniform seed maturation and reduces the risk of shattering during harvest.

Grain Quality

An oil content of 50-55% places D 37 in the high-oil hybrid segment. The black color of the seeds indicates high-quality hulls, which is crucial for storage and transport to crushing plants. The oil yield per hectare is achieved through the synergy of early maturity and high lipid concentration in the kernel.
