Abstract
Male sterile plants appeared in the population of N cytoplasm sugar beet strains, H-19 and H-2002, when their dry seeds were exposed to 50 kR gamma-ray, and the male sterility was maintained up to the M/sub 4/ generation through the mother plants. Cytoplasmic inheritance was confirmed by the reciprocal crossings between plants with normal phenotype from gamma-strains (progeneis of the male mutants which transmitted male sterility through the mother plants) and H-19 or H-1001. The crossing experiments suggested that various kinds of cytoplasm were induced by gamma-ray irradiation, and that different nuclear genes were responsible for the respective cytoplasms. A specific relationship between the pollen restoring genes and the sterile cytoplasms was established, and was named ''one set of pollen restoring genes for one cytoplasm''. It is probable that the cytoplasmic mutation occurred in normal cytoplasm strains and the specific combination between the altered cytoplasm and the recessive nuclear gene produced male sterility. Ethyl methane sulphonate, ethidium bromide, acriflavine and streptomycin were also effective in inducing cytoplasmic mutation in sugar beets.
