Narrative
Walnuts collected by Frank Meyer (USDA) in Peking, and donated to the USDA, Plant Introduction Station, Chico, CA. One seedling (PI 18256) was selected out of several hundred by LLoyd Joley at the Chico Station. Scions were taken to Salem, Oregon, by Moses Adams in 1927 where it was named Manregian. The name comes from a contraction of Manchuria and Juglans regia. It is now referred to commonly as Manregian. Seedlings from Manregian are sometimes used as rootstock and bear the same name. In phenology it is similar to Payne, but it is not laterally fruitful. A very large, hard shelled variety said to have come from the western mountains where it gets quite cold. Parent of Manregian rootstocks. The nut is large and round, the shell thin but strong. Kernel quality is good, but the kernel is somewhat dark. It is known for its hardiness to frost and some resistance to blight. Since the 1950's its seedlings have been recommended as a rootstock for walnut cultivars in Oregon to avoid blackline disease. Trees grafted on Manregian are reported to grow more rapidly than on black walnut rootstocks. However, their tolerance of salt accumulation is low. Forde of the Chico, CA, Plant Intro Station comments: "It may be a good rootstock in Oregon. It is not good here."
