Variety description

10 August 2026

The J-TE-G rootstock is characterized as dwarfing, providing tree growth approximately 30% weaker compared to the M9 rootstock. It has high yield efficiency; however, due to the small size of the trees, fruit size may be smaller than on more vigorous rootstocks.

Plants on this rootstock require intensive care, including regular irrigation and high-quality mineral nutrition. Features of the rootstock include the almost complete absence of root suckers and the need to install permanent supports to prevent tree lodging.
