“…Sorbus collina was initially considered to be apomictic (Lepší et al 2015), however, its genetic variability is higher than expected for an apomict (Feulner et al 2013). Furthermore, we detected morphological intermediates, mostly in areas where both S. collina and S. aria s. str.…”

“…The material stored in ice boxes was transferred into isolation tubes on the same day and kept stored at -80°C until isolation. Genomic DNA was purified from about 20 mg of leaf material as described in Feulner et al (2013), with the following modification: the initial homogenization volume was increased to 400 μl MC1 buffer supplemented with 10 μl RNAse A and homogenization duration in the MP FastPrep-24 tissue homogenizer (MP Bio, Santa Ana, USA) was increased to two times 40 s at a speed of 6 m/s. The genomic DNA was diluted tenfold with water and used for microsatellite analysis.…”

. (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 microsatellite markers, flow cytometry and multivariate morphometrics. In the Franconian Jura the tetraploid S. collina is the most frequent taxon in the S. aria complex. It consists of six closely related clones and a high number of unique genotypes, which were found in 70% of the populations studied. Morphologically, most of the clones and the unique tetraploid genotypes are not significantly differentiated. Therefore, all of them could be assigned to S. collina. Mechanisms that could result in the high number of genotypes within S. collina are accumulations of mutations, remnant sexuality, multiple polyploidization events and backcrossing. The results show that S. collina is a genetically quite variable facultative apomictic taxon. Triploids were identified sporadically and the microsatellites pointed to an origin from repeated hybridization events between diploid S. aria s. str. and S. collina. K e y w o r d s:
