RFLP map of peanut

Cultivated peanut (Arachis hypogaea L.) provides a significant source of oil and protein for large segments of the population, particularly in the less developed regions of Asia, Africa, and South America. In the United States, peanut is considered a high-value cash crop of regional importance, with production concentrated in the Southeast region of the country along with parts of Texas, Oklahoma, North Carolina and Virginia. Domestically, peanuts are grown primarily for use in the snack-food, peanut butter and confection industries, but also serve as an excellent source of mono-unsaturated cooking oil, as well as a source of meal for livestock.
