✦ Synopsis

Cultivars of T. aestivum crossed onto two lines with male sterility induced by the cytoplasm of T. timopheevi gave a high level of restoration in the F1 generation. The ratio of fertile to sterile plants segregating in the F2 generation was consistent with that expected for a single dominant restorer gene. The possible association between this gene and mildew resistance or some other desirable character derived from 'CI 12633', a common ancestor of the cultivars used, is discussed.
