Variety description

10 August 2026

J-KL-4 is a vegetatively propagated rootstock included in official agricultural variety registers. This designation belongs to the category of auxiliary horticultural materials and does not possess fruit variety characteristics such as ripening dates or fruit flavor quality.

The primary properties of J-KL-4 are determined by its scion compatibility and resistance to environmental factors. This designation is the result of research station breeding programs and is used in nursery production to modify the growth characteristics of grafted plants.
