- Jefferson - Release with immunity to Eastern Filbert Blight Disease. Produces a heavy yield of large flavorful nuts that fill their shells well. Similar to the standard Barcelona variety, but with fewer blanks and with a low incidence of shriveled kernels. A late bloomer. Pollinates best with Yamhill and Theta.
- Dorris - This latest OSU release is very productive. It is Eastern Filbert Blight immune and also produces early. Early ripening, very tasty nuts. It is a small tree at maturity.
- Theta - Blight immune release from OSU. Since Jefferson has a long bloom period and its female flowers are receptive late into spring, the male flowers of Theta will increase yields for Jefferson especially when used with other pollinators.
- York - York, named after a slave who proved invaluable in the Lewis and Clark Expedition, is widely compatible with other cultivars besides Dorris. It will be useful to the industry for decades to come, with good coverage throughout the bloom of Jefferson. Use York for early receptivity.
