Diversity of reproductive modes in Pilosella and its reflection in the structure of populations
The present paper evaluates breeding systems operating in the genus Pilosella and shows impacts of sexual mating in facultative apomicts if they function as maternal plants. This residual sexuality is an important source of...

Role of residual sexuality in apomictic plants: detection, rate and manifestation in populations of Pilosella (Asteraceae, Lactuceae)
Contribution of facultatively apomictic maternal biotypes to population diversity was evaluated in seven hybridizing populations of Pilosella in Central Europe, where the apomictic (P. bauhini or P. aurantiaca) and sexual (P. officinarum by ...

Sexual reproduction as a source of ploidy level variation in the model agamic complex of Pilosella bauhini and P. officinarum (Asteraceae: Lactuceae)
We studied the significance of sexual reproduction as a source of ploidy level bauhini and tetraploid, sexual P. officinarum. As the maternal parent, apomictic P. bauhini generated higher ploidy level variation than sexual ...

Enrichning ploidy level diversity: the role of apomictic and sexual biotypes of Hieracium subgen. Pilosella (Asteraceae) that coexist in polyploid populations
in facultatively apomictic versus sexual maternal plants that coexist in two model populations pilosella (usually sexual, less commonly apomictic), H. bauhini (apomictic), and their hybrids (sexual, apomictic, or sterile)....

Enriching ploidy level diversity: the role of apomictic and sexual biotypes of Hieracium subgen. Pilosella (Asteraceae) that coexist in polyploid populations
The population structure of two parental species and of their hybrids coexisting in two model populations was compared with the structure of the progeny which is generated by particular maternal plants in the field. With respect to ploidy level and r...

Residual sexuality of the apomict Pilosella rubra under natural conditions in the Krkonoše Mts.
Because of residual sexuality, a maternal facultatively apomictic plant is able to produce more than just apomictic progeny. The production of such non-apomictic progeny has been studied in open-pollinated Pilosella rubra, a hexaplo...

Impact of interspecific hybridization within a polyploid agamic complex of Pilosella (Asteraceae, Lactuceae) in Bulgaria compared with Central Europe
The species-mixed Pilosella populations comprising diploid sexual and polyploid gametes. The diploid sexual species in Bulgaria have a limited impact on interspecific of stabilised hybridogeneous species and scarcity of commonly hyb...
