Sunflower 807 A X 278 R

Hybrid sunflower 807 A X 278 R is a medium-maturing variety intended for cultivation in various regions of Russia, including the Central Chernozem, Volga, and West Siberian regions. The vegetation period varies from 113 to 130 days depending on climatic conditions, providing flexibility in agronomic timelines. The average yield of the hybrid reaches 28.0 c/ha in the Central Chernozem region and approximately 19.7 c/ha in the West Siberian region, indicating its high productivity across different soil-climate zones.

The hybrid is characterized by high resistance to downy mildew (races A-E), moderate resistance to white mold and false powdery mildew, significantly reducing the risk of yield loss. Plants reach an average height of about 160 cm, do not branch, have green leaf coloration, and strong pubescence. Seeds are distinguished by high weight — up to 72.8 g per 1000 seeds, with distinct marginal stripes and oil content ranging from 48.4-49.8%, making them valuable for producing high-quality oil.

For sowing, the recommended seeding rate is 55-60 thousand seeds per hectare, ensuring optimal plant density and maximum yield. The hybrid is suitable for conventional cultivation techniques and exhibits high drought resistance, allowing successful cultivation under conditions of insufficient moisture. Use of modern seed production technologies guarantees stable plant growth and development, making hybrid 807 A X 278 R a reliable choice for farmers aiming for high-quality sunflower yields.
