Kharkov 22 MC, a cultivar of winter wheat (Triticum aestivum L.) whose roots show a magnetotropic response, was crossed to Reward, a cultivar of spring wheat (T. aestivum L.), whose roots show no magnetotropic response. The magnetotropic responses of the F1, B2, F2, and B2 populations were the same as that of the female parent used in the crosses or backcrosses, showing that this characteristic is inherited through the cytoplasm.
