Variety traits

Kiwifruit maturity groups

Actinidia chinensis Planch.

In kiwifruit agronomy, cultivar classification by maturity groups is not used; harvest readiness is determined by laboratory sugar content indicators and phenological stages.

In the reference 14 varieties crop Kiwifruit, where this is mentioned in the description.

To determine kiwifruit maturity, instead of calendar dates, a maturity index is used, the main criterion of which is the content of soluble solids, measured with a refractometer as a percentage on the Brix scale. The start of harvest is usually set when a sugar threshold of about 6–7% is reached, which ensures proper consumer maturity.

Agronomic work planning is based on the analysis of phenological stages according to the BBCH scale, covering the period from flowering to physiological and edible maturity. Ripening times depend on varietal characteristics and the sum of active temperatures, while failure to adhere to harvest timing critically affects fruit shelf life and flavor quality.
