Persian walnut (Juglans regia L.) is an important tree primarily for its nutritious nuts and high-quality wood. Based on the analysis of literature sources, it was found that hybridization played a significant role in the evolution of the genus Juglans. Persian walnut can interbreed with many walnut species with the formation of fertile hybrids. There are two-species, three-species, and four-species hybrids in different combinations of crossings. They are used in forestry as a source of wood, in horticulture as rootstocks, and in breeding for more durable resistance against pathogens and tolerance against abiotic stresses. Some interspecific hybrids have validly published scientific names, but many of the proposed names do not meet the rules of the International Nomenclature Code for algae, fungi, and plants.
