Abstract

Natural crossing in peanuts (Arachis hypogaea L.) averaged 0.27, 0.09, and 0.23% when measured by counting the hybrids with two marker varieties, at Holland, Va., from 1963 to 1965. Varietal as well as seasonal differences were noted. Highest natural crossing occurred in 'Tennessee Red,' 0.40% (range = 0.15 to 0.55%), and the lowest in 'Virginia Bunch 67,' 0.10% (range = 0.01 to 0.24%) . Natural hybridization in peanuts at Holland is much less than that reported for other areas, but it is sufficient to account for 10 to 544 (4 to 220 plants/acre) "off type" plants/ha, and should be a consideration in maintaining varietal purity at this location.
