摘要：

Three new sources of cytoplasmic male sterility in tobacco with interspecific origin are reported. The wild species Nicotiana excelcior Black (n = 19), N. amplexicaulis Burbidge (n = 18) and N. rustica L. (n = 24) are used as donor of cytoplasm. Nuclear donor is N. tabacum L. (n = 24). The genetic effects of cytoplasmic-nuclear interactions of the studied species are discussed. Our experiments prove that N. excelcior; N. amplexicaulis and N. rustica are carriers of cytoplasmic genes for male sterility that express in combination with nuclear genes of N. tabacum.
