Description	Hieracium subgen. Pilosella group has a high diversity of species, subspecies and hybridogenous types which is based on the reproductive diversity (clonal growth and sexual and/or apomictic seed reproduction). The study found that (1) Apomicts produced more variability than that of sexuals. Whereas progeny of sexual mothers was formed almost exclusively by hybridization via fusion of reduced gametes (n+n hybrids), the progeny of facultatively apomictic mothers has originated via four different pathways, i.e. apomixis (somatic parthenogenesis, 2n+0), hybridization via fusion either of reduced (n+n hybrids) or unreduced (2n+n hybrids) gametes and haploid parthenogenesis (n+0). (2) The high-polyploid hybrid biotypes (heptaploids, octoploids) generated a much variable progeny. (3) Higher ploidy level variability within the seeds than that within the seedlings confirmed the selection of specific progeny classes (namely polyhaploids, n+0) during germination and early development of seedlings.
