Cytoplasmic male sterility (cms) and nuclear male sterility (nms) in Petunia were described respectively as possible "autonomous" and "integrated" states of the same genetic element by Frankel (1971). In the present study we describe genetic analysis of the interaction between the cms, the nuclear gene for male sterility (e) and the fertility restorer allele (Rf). The main findings in this study are: (1) The nuclear sterility allele can coexist in one or two dosages with the cytoplasmic male sterility elements (ste) in somatic cells or female gametes; (2) the presence of the fertility restorer allele Rf is not required for the coexistence of ste and e and (3) Rf does not interact epistatically with e, e.g., the expression of e is independent of Rf-the genotypes (S) RfRfee and (S) Rfrfee are male sterile. © 1984 Springer-Verlag.
