Currant YUKHNOVSKAYA 70

Cultivation Practice: The Yukhnovskaya 70 Variety

For any grower working with black currants, operational efficiency is paramount. The Yukhnovskaya 70 variety, developed by the A.G. Lorch Potato Research Center, is characterized by its predictable field performance. The variety matures in 45–55 days after bud break, allowing for precise planning of harvest schedules and logistics. Its stable performance makes it a reliable choice for consistent yields.

Disease Resistance and Maintenance

Managing the Yukhnovskaya 70 is straightforward, primarily due to its genetic resistance to major pathogens, which helps in reducing the need for intensive fungicide applications:

• Anthracnose: highly resistant, minimizing the risk of outbreaks.
• Spotting: excellent resistance to Mycosphaerella leaf spot and brown spot.
• Septoria: high tolerance, which is crucial for maintaining plant health in humid conditions.

Structural Characteristics and Field Care

The architecture of the bush is a key advantage for plantation maintenance. Yukhnovskaya 70 grows as a compact, medium-spreading bush. This structure facilitates easier movement of machinery between rows and simplifies both manual and mechanical harvesting. Because the shrub is not overly sprawling, the lower branches stay clear of the soil, reducing the contact with ground-borne pathogens and ensuring that the fruit remains clean. Furthermore, this compact growth habit ensures proper air circulation within the canopy, which is a natural barrier against fungal diseases. This allows the operator to maintain a higher planting density while keeping the maintenance requirements per plant relatively low.
