Abstract

A new and distinct variety of walnut rootstock denominated ‘RX1’ is described. This new variety, ‘RX1’, can be propagated through standard tissue culture micropropagation. It has excellent survivability in the nursery and orchard. The new variety also has reduced susceptibility to damage from Phytophthora citricola in greenhouse screens and in the field compared to other available walnut rootstocks.
