Breeding systems and continuing evolution in the endemic Sorbus taxa on Arran.

Heredity - 1 Nov 2004

Robertson A, Newton A C, Ennos R A

Abstract excerpt

The Arran whitebeams Sorbus arranensis and S. pseudofennica are two endemic woody plant taxa that have evolved on Arran through hybridisation. S. arranensis is a triploid hybrid between the widespread diploid S. aucuparia and the rare tetraploid S. rupicola. S. pseudofennica is a tetraploid formed by crossing between S. arranensis and S. aucuparia. In order to determine the mating systems of the two endemic...
