A walnut is the nut of any tree of the genus Juglans (Family Juglandaceae), particularly the Persian or English walnut, Juglans regia.
The two most common major species of walnuts are grown for their seeds – the Persian or English walnut and the black walnut. The English walnut (J. regia) originated in Persia, and the black walnut (J. nigra) is native to eastern North America.
In 2016, worldwide production of walnuts (in shell) was 3.7 million tonnes, with China contributing 48% of the world total (table).[3] Other major producers were (in the order of decreasing harvest): United States, Iran, Turkey, Mexico, Ukraine and Chile.
