Abstract
SEVERAL papers1–6 have been published in which it is claimed that mitochondrial heterosis and mitochondrial complementation are related to the yield potential of F1 hybrid cereal cultivars. Mitochondrial heterosis is measured by the superior oxidative and phosphorylating efficiency of mitochondria isolated from heterotic F1 hybrid cultivars when compared with those isolated from the corresponding parental cultivars. Although these parameters can be measured only after a small quantity of F1 hybrid seed has been produced they may prove useful to plant breeders as a preliminary appraisal of the yield potential of an F1 hybrid before undertaking extensive field trials.
