Sexual reproduction as a source of ploidy level variation in the model agamic complex of Pilosella bauhini and P. officinarum (Asteraceae: Lactuceae)

Original language description

We studied the significance of sexual reproduction as a source of ploidy level variation in a model system consisting of hexaploid, facultatively apomictic Pilosella bauhini and tetraploid, sexual P. officinarum. As the maternal parent, apomictic P. bauhini generated higher ploidy level variation than sexual P. officinarum. Ploidy levels of its progeny ranged from triploid to octoploid under experimental conditions and even to decaploid in the field. This progeny diversity resulted from the breeding system in P. bauhini, which included haploid parthenogenesis and sexual reproduction through both reduced and unreduced gametes besides prevailing apomixis; these particular reproductive pathways have been quantified. Sexual P. officinarum, on the other hand, reproduced exclusively through fusion of reduced gametes and produced only pentaploid hybrids or tetraploid progeny from autogamy, allogamy or both. Surprisingly, sexual P. officinarum was also the species showing stronger reproductive
