J-KL-3 is classified as propagation material (rootstock) for growing apple seedlings, rather than a fruit variety for yield production. It is used for forming trained or standard tree shapes, ensuring the viability of the scion grafted onto it.
This rootstock is included in the lists of registered materials in the Czech Republic and Slovakia. Due to its functional purpose, varietal characteristics such as maturity group or fruit tasting scores are absent.
