Abstract

Genetic variances for yield and several fruit traits for the F5 and F6 generations of an intercultivar peanut (Arachis hypogaea L.) cross were estimated by maximum likelihood procedures from a nested mating design. Estimates of additive and additive by environmental variances were significant for yield and the fruit traits for the cross between the two Virginia (ssp. hypogaea var. hypogaes) cultivars. Estimates of additive by additive variance were essentially zero for all traits; however, estimates of additive by additive by environmental variances were larger than their associated standard deviations for all traits except yield....
