Vigor Matters.
Duarte Nursery’s high-vigor clonal pistachio rootstocks will bring your production to the top.
We selected our VigorClone rootstock lines from UCB-1 seedlings and field trialed them for decades to prove their exceptional vigor, tolerance, and productivity.
VigorClones have the verticillium and salt tolerance of the UCB-1 with significantly improved uniformity and size, making them the best choice for pistachio orchards.

VigorClone Field Trials
Contact a field rep to visit a Duarte VigorClone field trial in your area.
The data from our pistachio field trials shows how vigorous rootstocks lead to increased production. We planted Duarte Indiana Ranch in 2015 to test VigorClone selections D110 and D71 against UCB-1 seedling trees.
In 2025, the VigorClone trees had 20% bigger canopies than UCB-1 and produced over 30% more ACP crop at 2024 harvest.
