Hazelnut PollyO

American Breeding for Modern Orchards

The hazelnut variety 'PollyO' is the result of extensive breeding work by specialists at Oregon State University (USA). In 2025, the variety was officially registered in the State Register of Plant Varieties of Ukraine, opening new opportunities for domestic producers focused on industrial nut cultivation.

Adaptability and Agrotechnics

'PollyO' demonstrates excellent adaptability to various climatic conditions in Ukraine. The variety has successfully passed trials and is recommended for cultivation in all key zones: Steppe, Forest-Steppe, and Polissya. This makes it a versatile solution for farms across different geographical locations.

The plant is characterized by strong growth vigor and a semi-upright habit. A key feature for industrial hazelnut farming is the weak tendency to produce root suckers, which significantly simplifies orchard maintenance and reduces pruning costs. The bush forms a moderately dense canopy, promoting good aeration and fruit exposure to sunlight.

Technological Characteristics of the Nut

The variety belongs to the mid-early ripening group and is intended for technical use. This means 'PollyO' was developed with the specific requirements of the processing industry in mind:

• Yield Formation: The clusters typically contain 3 to 4 nuts.
• Kernel Characteristics: The kernel is of medium size and has a regular spherical shape, which is the standard for high-quality processing.
• Quality Control: A significant advantage is the absence of double kernels, which increases the commercial value of the harvest.
• Appearance: The nut features a light brown color, a spherical shape, and a small basal scar, facilitating the cleaning process.

The flowering of female and male flowers occurs almost simultaneously, which is highly beneficial for pollination. The male catkins are green, while the stigmas exhibit a characteristic pink hue.

Registered in 2025, 'PollyO' represents one of the most modern offerings on the planting material market, combining high American breeding standards with proven adaptability to Ukrainian soil and climatic conditions.
