Several peanut (Arachis hypogaea L.) breeding lines in the Florida program were highly variable even after constitution from single plant selections after 21 generations of assumed self-pollination. To assess potential causes of this variability a 3-yr study was conducted to determine outcrossing using Krinkle as a genetic marker. There was a significant year by genotype interaction in this study. Two breeding lines with Virginia botanical types averaged almost 1.5 outcrossing, and in 1990 more than 3 of the progeny from these lines were the result of outcrossing. The breeding line Valencia 803 averaged nearly 8 outcrossing, and a second Valencia type, F623, averaged over 4.
