Patterns of genetic variation in Pilosella echioides and its selected relatives: results of variation in ploidy level, facultative apomixis and past and present hybridization

Result description

We used allozymes to elucidate the genetic variation of Pilosella echioides and P. rothiana in the Pannonian Basin and its relationship with morphology and modes of reproduction. The former species consists of sexual diploid, apomictic tetraploid, and very rare sexual tetraploid populations; the latter is exclusively tetraploid and apomictic. As expected, we detected the highest intra-population variation in diploid populations of P. echioides. Nonetheless, 73 % of populations of tetraploid P. echioidesand 64 % of P. rothiana consisted of 2-7 multilocus allozyme genotypes, the means being 5.75 in P. echioides and 2.64 in P. rothiana. Both the proportion of distinguishable genotypes (G/N) per population and genotype diversity (D) per population significantly differed between diploid P. echioides (means 0.415 and 0.828, respectively) on the one hand and tetraploid P. echioides (means 0.252 and 0.387, respectively) and P. rothiana (means 0.213 and 0.347, respectively) on the other.
