A New Source of Cytoplasmic—Genic Male Sterility in Pearl Millet1

  1. M. E. Aken'Ova and
  2. H. R. Chheda2



A male-sterile plant was discovered in a population of ‘ex-Bornu’‘gero’ pearl millet [Pennisetum americanum (L.) Leeke] of northern Nigeria in which male sterility had not previously been found. To determine the relationship between the ex-Bornu source of male sterility and the three known male-sterility sources in pearl millet, ‘gero-l’ and ‘gero-2’, two plants that were good maintainers for male-sterile ex-Bornu, were each crossed with three pearl millet lines namely Tilt 23A1, 239A2, and 426A3, which represented the known malesterility sources in pearl millet. Gero-1 and gero-2 were good maintainers for 426A3 and 239A2, respectively, but neither was a good maintainer for all three sources. The results suggest a new pearl millet male-sterility source operating in ex-Bornu.
