Variety description

10 August 2026

Coco 4 is a specialized clonal rootstock obtained using in vitro micropropagation technologies. It is used by professional nurseries for grafting various hazelnut varieties, ensuring the absence of root suckers, which significantly simplifies the maintenance of plantations.

Data on morphological characteristics, such as plant height or disease resistance, are absent in open sources, as this is a specialized rootstock, not a fruit variety. Scientific works are focused on the propagation efficiency of this clone and the survival rate of crops grafted onto it.
