Grape Amur

Technical potential of 'Amur': grapes for extreme viticulture

The 'Amur' grape variety, developed by breeders at KubSAU and AF 'Yuzhnaya', is a specialized technical variety focused on producing high-quality wine materials in regions with harsh climatic conditions. The key technical solution of this variety is the combination of high frost resistance (down to -27°C) with biological resilience against specific pathogens, eliminating the need for costly winter covering procedures.

Biological parameters and adaptation

The vine's growth vigor is classified as strong, requiring precise pruning strategies for effective vegetative mass distribution. The clusters are medium-sized (300–500 g), while the blue berries, weighing 2–5 g, possess a standard flavor profile and sugar accumulation ranging from 16% to 20%. For technical viticulture, these metrics ensure a stable yield of must during processing.

Phytopathological resistance and productivity

• Protective barrier: The variety demonstrates pronounced resistance to phylloxera and a moderate resistance to downy mildew. This reduces the frequency of chemical treatments, which is critical for reducing grape production costs.
• Late ripening: The extended vegetative period promotes gradual vine maturation, which correlates directly with the variety's frost resistance.
• Yield: The genetic potential ensures high returns per hectare, making 'Amur' an economically viable choice for industrial vineyards in non-covering cultivation systems.

This variety is a robust tool for those planning to establish vineyards in northern industrial viticulture zones, where the primary success factor is the vine's ability to withstand critical winter temperatures without additional capital investment in winter protection measures.
