Part of the Biotechnology in Agriculture and Forestry book series (AGRICULTURE, volume 30)


As one of the world’s most important nut crops, walnuts are produced in amounts exceeding 800 000 metric tons annually and the wood from walnut trees is valued for furniture, veneer, and gunstocks. For these products, walnuts are cultivated in the United States, China, Turkey, France, and many other countries. The English or Persian walnut, Juglans regia, is native to the mountains of central Asia. It is a member of the Juglandaceae which includes black walnuts (J. nigra, J. hindsii, J. major), butternut (J. cinerea), pecans and hickories (Carya spp.), and wingnuts (Pterocarya spp.) (McGranahan and Leslie 1990).
