"175;201" . . . "Hieracium subgenus Pilosella is an extremely difficult group taxonomically, as it combines apomixis with extensive hybridisation. The study presents a multidisciplinary approach combining DNA fingerprinting and the analysis of chloroplast DNA with morphological-taxonomic studies, cultivation, experimental hybridisation, analysis of ploidy level and mode of reproduction. Several species of a hybridogenous complex were studied in detail at clone, population and species level. Different levels of variability were found in apomictic species that were related to different ages: from near uniformity to variability within the locality. Chloroplast haplotypes formed two major groups and often indicated unidirectional transmission of cpDNA, despite multiple origins of most apomicts. Moreover, often the facultative apomict rather than the sexual species acted as seed parent. Thus, the residual sexuality of the apomicts plays a larger role in the speciation of this group than assumed." . "RIV/67985939:_____/05:00030447" . "Br\u00E4utigam, E." . . "520811" . "Koeltz" .
