Genetic variation in Irish Whitebeam, Sorbus hibernica E. F. Warb. (Rosaceae) and its relationship to a Sorbus from the Menai Strait, North Wales

摘要

Genetic variation within the Irish endemic Sorbus hibernica, Irish Whitebeam, and its relationships to 5. aria, S. eminens, S. porrigentiformis and a taxon from the Menai Strait have been assessed using AFLPs and morphology. Sorbus hibernica is genetically distinct from S. aria, S. eminens and S. porrigentiformis but is close to the Menai Strait taxon. Sorbus hibernica cannot be separated from the Menai Strait taxon using leaf or fruit characters, but they differ in ploidy.
