Three breeding systems can be recognized in Central European Cirsium: dioecy, hermaphroditism and gynodioecy. Female frequencies differ substantially in the gynodioecious species based on our field data from 1903 populations representing 78250 individuals. Using RAD-Seq and pollination experiments, we are going to investigate how self-compatibility is related to the type of breeding system, female frequency in gynodioecious species, and heterozygosity. Self-compatibility is absence or breakdown of genetic mechanisms by which the maternal plant can recognize and reject pollen grains expressing alleles in common with the maternal genotype. Therefore, self-compatibility should result in low levels of heterozygosity. Our preliminary results show that gynodioecious Cirsium heterophyllum with high female frequency and hermaphroditic C. canum are both self-compatible with low level of seed production.
