Description	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) biotypes coexist. The parental species were tetraploid (exclusively P. aurantiaca, commonly P. officinarum, rarely P. bauhini), pentaploid (commonly P. bauhini, rarely P. officinarum), or hexaploid (P. officinarum, P. bauhini). Recent hybrids co-occurred with their parental species in all populations. Plants in the field were studied with respect to ploidy level, reproductive system, morphological characters, clonal structure and cp-DNA haplotypes. Identification of those progeny products which had arisen by virtue of residual sexuality in maternal apomicts, was also based on the morphological and reproductive characters in cultivated progeny, that were found different from their maternal parent.
