INTRODUCING: GRIZZLY CLONAL WALNUT ROOTSTOCK™ (USPP 31,862)
IT “THRIVED WHEN ALL THE REST BARELY SURVIVED!” ™
The FIRST WALNUT ROOTSTOCK
- cloned due to its superior performance in a commercial orchard!
- cloned due to its superior performance in a replant walnut orchard!
- observed with a variety on it for 20 years!
We planted Chandler on Grizzly Clonal Walnut Rootstock ™ in this challenging replant site and saw astonishing results when compared to Chandlers on VX211, RX1, Vlach or any seedling paradox.
We currently have Grizzly Clonal Walnut Rootstock ™ in replicated field trials in multiple orchards and it is among the largest and most productive of all rootstocks in all trials, including current commercial rootstocks. We have never observed crown gall on Grizzly Clonal Walnut Rootstock ™.
The “Mother” tree (shown below) of Grizzly Clonal Walnut Rootstock ™ is a Tulare variety grafted onto a seeding Paradox rootstock. It thrived when all the rest barely survived, in an orchard that faces many challenges. Our early data indicates this rootstock is, indeed, a bigger, tougher, more productive tree.
This orchard (below), planted in the 90’s is a replant site after removal of extremely large Serr trees. Much of the orchard is very sandy soil, so the replanted orchard had to contend with replant disorder, heavy populations of lesion nematodes, generally low nutrition and poor soil structure. It’s no wonder that the average walnut tree struggles… and it is from this orchard that we found, and cloned, Grizzly Clonal Walnut Rootstock™.
