Abstract

The analyses of diagnostic morphological characters and allozyme loci to assess the genomic composition of natural hybrids T. montandoni x T. vulgaris were used. The analyses revealed combinations of both morphological and allozyme species-specific markers in the hybrids that were not compatible with them being of Fl generation, indicating that at least some of the hybrids were recombinants. These findings point to the need for delimiting the extent of hybridization and its role in the evolution of T. montandoni and T.vulgaris. The results provide strong evidence that hybrids segregated, i.e, they were not clonal, and, therefore, we argue against the previously proposed hypothesis that T. montandoni x T. vulgaris hybrids reproduce by hybridogenesis.
