Abstract
Reciprocal differences for male sterility, dwarfism and morphological traits have been studied in intra- and interspecific crosses of five Epilobium species. Male sterility occurred in two interspecific hybrids with E. montanum as the male parent while dwarfism has been found to varying degrees in three interspecific crosses with E. watsonni. In contrast to transient differences in plant height and leaf morphology in reciprocal hybrids of the cross between E. hirsutum and E. parviflorum, male sterility and dwarfism persistently occur as reciprocally different traits which may be influenced by determinants of the cytoplasm. The molecular characterization of the plastid DNA of the parental lines and the F1 hybrids indicate that the plastome of male sterile and dwarf plants is identical to that of the female parents. Furthermore, in spite of these developmental disturbances, the expression of plastid genes coding for polypeptides of thylakoid-membrane complexes is unchanged. Thus, it seems unlikely that the genetic compartement of the plastids is responsible for the expression of the male sterile or the dwarfed phenotype.
