Rare hybrid swarm of Pilosella polymastix P. officinarum: cytotype structure and modes of reproduction

Original language description

The tetraploid parental Pilosella species gave rise to the hybrid swarm analyzed: sexual P. officinarum and apomictic P. polymastix (P. bauhini?P. caespitosa). In addition, the swarm consisted of a) a stabilized tetraploid apomictic P. melinomelas represented by two isozyme phenotypes, and b) tetraploid and sexual hybrids between P. officinarum-P. polymastix, with 16 isozyme phenotypes in the 18 plants analyzed. We also found pentaploid P. bauhini (three plants comprising one isozyme phenotype), one hexaploid plant corresponding to P. melinomelas (putative 2n + n hybrid) and one pentaploid plant (probably a hybrid between hexaploid and unknown tetraploid). The single triploid plant detected in the hybrid swarm is probably of polyhaploid origin.
