IS 4-6

Technical Profile of the "IS 4-6" Pear

Developed by the Institute of Horticulture of the NAAS, this hybrid serves as a prime example of adaptive fruit material tailored to the climatic realities of Ukraine. The core technical feature of this hybrid is its genetically encoded resistance to major pathogens and temperature stresses.

Biological Resilience and Productivity

The primary technological asset of the "IS 4-6" is its high resistance to fire blight and scab. In an intensive orchard setting, this is a critical factor that reduces the necessity for fungicide applications. The plant's defense system is calibrated for extreme temperature fluctuations: high frost resistance (down to -30°C) allows the crop to be grown without the risk of wood freezing in most of Ukraine's agro-climatic zones.

Fruit Parameters and Organoleptic Properties

The variety is characterized by large fruit size (ranging from 180g to over 250g), placing it in the high-grade commercial category. The visual profile of the fruit combines a yellow-green base with an intense red-blush overlay, significantly increasing its retail appeal.

• Flavor Profile: A balance of sugars and acids creates a rich sweet-and-sour taste with distinct aromatics.
• Utilization: A universal variety suitable for both fresh market consumption and processing.
• Ripening Period: A summer variety ensuring early market entry.

Investing in this hybrid means choosing consistent yields through the mitigation of biological risks and high-quality fruit output.
