California Walnuts Are the First Choice Worldwide
The demand worldwide for California walnuts is growing steadily. New markets are up for grabs in India, China, Hong Kong, Turkey, and the Middle East. As more and more research touts the benefits of walnuts in fighting disease and helping control diabetes, among other thing, this demand may very well still be in its infancy.
Advantages of Clonal Walnut Rootstock
Clonal Walnut Rootstocks can greatly increase growers’ returns. With Clonal RX-1 (USPP # 20, 649), VX-211 (USPP # 21, 179) and Vlach, growers are enjoying significantly higher production, larger more vigorous trees, Phytophthora and Nematode resistance, increased disease tolerance and more uniform trees.
Agromillora Clonal Walnuts are delivered through advanced nursery propagation capabilities including in vitro micro propagation technology and highly controlled greenhouses.
The rootstocks are delivered in a plastic container with a virgin non-soil growing media. Field grafting with scion occurs approximately four months following planting. Year round planting is an option in most situations.
RX1 (USPP # 20, 649) ~ Available as potted roostock
A Texas Black crossed with English selection. It is moderately resistant to Phytophthora with average vigor and is currently being tested for response to nematodes. It has survived well in all field tests. A UC Davis patent has been filed on this selection.
VX211 ( USPP # 21, 179) ~ Available as potted roostock
A standard paradox rootstock, a cross of Northern California Black and English. It’s considered root lesion nematode “tolerant” because, unlike “regular” seedling paradox, it survives and grows very vigorously in soils with high lesion nematode populations. This selection also has moderate resistance to Phytophthora and survives well in field tests. A UC Davis patent has been filed on this selection.
Vlach ~ Available as potted rootstock
A commercial standard Paradox rootstock, (J.hindsii x J.regia) grown by micro-propagation, which originated from a vigorous Paradox tree in Stanislaus County.
