Pedigreed natural crossing to produce marker-idenpngied hybrids for specific uses has been exploited in USDA-ARS/Georgia cooperative peanut (Arachis hypogaea L.) germplasm enhancement projects since the discovery in 1959 of suitable genetic markers. The principal advantages of natural hybridization using dominant alternative alleles to idenpngy the outcrosses are that (1) the production of F1 hybrid plants is not dependent upon conventional manual emasculation, (2) the idenpngication and harvest of plants exhibiting the markers can be performed by semiskilled workers, and (3) the procedure is more economical than the standard crossing method.
