Abstract: . (2017): Genetic variability and morphology of tri-and tetraploid members of the Sorbus aria complex in northern Bavaria. -Preslia 89: 275-290.The Sorbus aria complex in the Franconian Jura, northern Bavaria, consists of the sexual diploid S. aria s. str. and putative apomictic polyploids, among them S. collina and S. danubialis. Here, the genetic and cytotypic structure of the S. aria complex and the proportion of clonal versus variable genotypes with a special focus on S. collina are studied using nuclear m… Show more

“…The genetic data revealed a clear divergence among (groups of) populations included in different allotetraploid apomictic lineages that originated in various parts of South-Eastern and Central Europe. Our results thus support previous findings that hybridisation, polyploidization, and apomixis are the main drivers of Sorbus diversification, at least in Europe [ 33 , 34 , 36 , 82 ].…”

“…This high genetic variability, together with the cross-propagation system, confirmed by our study, is characteristic mainly for diploid Sorbus species ( Ludwig et al 2013 ; Hamston et al 2018 ). Although both diploid and triploid populations of S. aria have been found in Central Europe ( Ludwig et al 2013 ; Feulner et al 2017 ), the observed pattern of genetic variability and structure of the tested population of S. aria is a consequence of interbreeding of diploid genomes.…”

“…Results from morphometric studies, for which usually more representative number of characters was screened, are non-unequivocal. Some studies found either relatively weak (Marhold 1999; Hodálová et al 2007) or missing (Saukel and Länger 1990; Feulner et al 2017) differentiation between diploids and the autopolyploid derivatives. Our results are in good accordance with these studies and support the notion that autopolyploids usually resample the morphospace of their parents (Soltis et al 2007).…”
