Abstract
Estimates of additive, dominance, maternal, and paternal components of variance were obtained for a sample of 18 traits, including measurements of yield, scapes, flowers, disk, ray and trans florets, leaves, and branching in the Davis population of Gerbera hybrida. The results, based on the covariance of reciprocals, indicate that although heritability averaged 0.52, extranuclear maternal or paternal effects are not important sources of variability. Therefore, reciprocal differences do not seriously affect estimates of additive variance or heritability in this population.
