Somatic Embryogenesis in Peanut (Arachis hypogaea L.)
Arachis hypogaea L., the cultivated peanut, also called groundnut, is an important source of oil and protein and makes a major contribution to human nutrition. Peanut is native to South America with its primary center of origin believed to occur in southern Bolivia or northern Argentina (Gregory and Gregory 1976). Commercial production is found primarily between 40 °N and 40 °S latitude (Cobley 1985). Approximately 20.1 million ha are devoted to peanut production worldwide, and the major producers are India, China, the United States, and Senegal. Annual world production for the 1991–1992 marketing year is 22.7 million metric tons (USDA Official Data). Most of the world’s peanut crop is crushed for the extraction of edible oil and protein meal. It is also an important whole seed food and ingredient of processed foods.
