Název v původním jazyce

The detecte, rate and manifestation of residual sexuality in apomictic populations of Pilosella (Astreraceae, Lactuceae)

Popis výsledku v původním jazyce

Effect of maternal facultatively apomictic plants on population diversity was evaluated in seven hybridizing polyploid Pilosella populations, where apomictic (P. bauhini or P. aurantiaca) and sexual (P. officinarum) biotypes coexist. The ploidy level, reproductive system, morphology, clonal structure and chloroplast DNA haplotypes were used to characterize these plants and their hybrids. The reproductive origins of the progeny were assessed through either a flow cytometric seed screen and/or a comparison between the ploidy level of progeny embryos/seedlings and the maternal ploidy level. The cultivated progeny derived from residual sexuality in maternal apomicts were also identified based on their morphology and reproductive behaviour. The progeny different from their maternal parents (0.6?92.3 % of progeny embryos and 0?100 % of progeny seedlings) originated either sexually or via haploid parthenogenesis.
