Allozymic differentiation of the Antirrhinum majus and A. siculum species groups.

ABSTRACT:

Background and aims

Fifty-two populations were sampled in order to establish the taxonomic delimitation and relationships of eight taxa belonging to the A. majus L. and A. siculum Miller groups.

Methods

Data on 13 allozyme loci were recorded after extraction of fresh leaves and electrophoresis on horizontal 10% starch gels.

Key results

Genetic distances between conspecific populations are lower than for other species of the genus.

Conclusions

These results support the recognition of A. majus, A. tortuosum, A. linkianum, A. cirrigherum, A. litigiosum and A. barrelieri at specific rank. The genetic distances, together with the lack of morphological differences and the sympatric distribution ranges, support the inclusion of A. australe into A. tortuosum, A. dielsi
