HA-1 A SU

High-Performance Stability in Stress Conditions

The Austrian selection from Saatbau has established a reputation for meeting the needs of agronomists who demand both high yields and robust plant health. The «ХА-1 А СУ» hybrid is a top choice for fields with high infection pressure, where protecting the harvest from pathogens is the primary economic priority.

A Strong Barrier Against Major Pathogens

This hybrid is specifically designed for environments conducive to fungal outbreaks. Agronomists select «ХА-1 А СУ» for fields with intensive crop rotation where soil-borne pathogens make it difficult to cultivate less resistant varieties. The genetic profile, developed by Saatzucht Donau Ges.M.B.H. & Cokg, offers comprehensive field immunity:

• Fungal Resistance: A high tolerance threshold for Verticillium, Sclerotinia, Phomopsis, and Rust, reducing the need for aggressive fungicide applications during critical growth stages.
• Leaf Health: Proven resistance to Powdery Mildew and Downy Mildew (Peronospora), keeping the foliage functional until full maturation.

Agronomic Profile and Field Management

Standing at 170–180 cm, «ХА-1 А СУ» provides excellent uniformity, which simplifies mechanical harvesting and minimizes header losses. The large, black seeds are prized for their quality and a consistently high oil content ranging from 45% to 50%.

Field data indicates that this hybrid reaches its full potential on fertile soils, yet remains highly predictable and reliable even in less-than-ideal conditions. For farm managers, selecting «ХА-1 А СУ» is a strategic decision to secure high-quality, high-oil sunflower yields while mitigating the risks associated with crop disease outbreaks.
