In two crosses between wild and cultivated pearl millets nucleo-cytoplasmic male sterile plants have been created by transfer of a cultivated genotype into a wild cytoplasm. The phenomenon is not reciprocal : the wild genotype placed in cultivated cytoplasm maintains an excellent male fertility. A completely male sterile BC7 line in wild cytoplasm background greatly resembling the cultivated parent, has been constructed from one of the two crosses. The genetics of its restoration seems to imply three independent genes (2 major and 1 minor). Restoration tests of this new male sterile line indicate that it is different from the three known male sterile sources A1, A2 and A3. Wild forms seem to possess a higher frequency of restorer alleles than cultivated forms, regardless of their geographical origins. (Résumé d'auteur)
