Soybean RGT SPEEDA

Genetic Architecture and Productivity

The French RAGT breeding program focuses on the balance between early maturity and intensive accumulation of organic compounds for the RAGT Speda variety. With a vegetation period of 100–110 days, this hybrid is classified as mid-early, which is vital for regions experiencing late-summer moisture deficits. The plant successfully forms well-filled pods before peak thermal stress sets in.

Seed Biochemical Profile

Profitability is driven by protein and oil yields. RAGT Speda exhibits a protein content of 43–45%, positioning it in the premium segment for the processing industry. An oil content of 20–21% is optimal for standard industrial extraction lines. This high protein concentration is the result of RAGT's focus on enzyme activity, enabling the plant to efficiently utilize soil nitrogen and symbiotic processes.

Phytopathological Resilience

RAGT’s engineering approach to protecting RAGT Speda relies on multi-layered resistance to key pathogens:

• Peronospora: The variety effectively suppresses downy mildew development in early stages, preventing damage to the leaf canopy.
• Fusarium: The root system possesses enhanced resistance to soil-borne fungi, ensuring consistent plant density across the field.
• Bacteriosis: Due to a robust cuticle and specific cell sap composition, the hybrid successfully resists bacterial infections, maintaining its photosynthetic surface until the end of the season.

The practical value of this defense array lies in reduced fungicide expenditure, directly enhancing per-hectare profitability.
