Variety traits

Maturity group — Corylus avellana

Corylus avellana L.

The concept of "maturity group" is not applied to hazelnuts; it is replaced by ripening periods, which are determined by phenological traits and the duration of the interval from pollination to physiological maturity.

In the reference 85 varieties crop Common hazel, where this is mentioned in the description.

For Corylus avellana, there are no fixed scales for maturity groups. Crop readiness is assessed visually by the change in husk color from green to yellow or brown, the nut shell acquiring its characteristic brownish-yellow hue, and the natural abscission of the fruits.

In hazelnut agronomy, cultivars are classified by ripening periods into early-maturing, ripening in August, and late-maturing, reaching maturity in September. The full development cycle of the fruit from the pollination phase to harvest readiness ranges from 150 to 180 days and depends on climatic conditions and the characteristics of the specific cultivar.
