RX1 is a clonal walnut rootstock, a hybrid of Juglans microcarpa and Juglans regia, known for its excellent resistance to Phytophthora, a soil-borne pathogen that causes root and crown rot. This makes it an ideal choice for orchards with high disease pressure. RX1 also provides moderate vigor, promoting healthy tree growth while supporting good yields. It performs well in a variety of soil types, particularly in well-drained soils, and is compatible with a range of English walnut varieties. Its combination of disease resistance, adaptability, and consistent performance makes it a valuable rootstock for commercial walnut growers looking to enhance orchard longevity and productivity.
