Název v původním jazyce

Allozyme variation in diploid, polyploid and mixed-ploidy populations of the Pilosella alpicola group (Asteraceae): Relation to morphology, origin of polyploids and breeding system

Popis výsledku v původním jazyce

Our study showed that genetic differentiation among morphologically well-defined species of the P. alpicola group inferred by allozymes was rather low. The Western Carpathian populations of P. ullepitschii formed the only genetically well-differentiatedgroup. The same allele suite shared by all cytotypes of P. rhodopea and presence of both balanced and unbalanced heterozygotes in tetraploids was consistent with autopolyploid origins of polyploids and provided further evidence for a primary contact zone. An isolated relic population of P. rhodopea from the Southern Carpathians exhibited lowered values of genetic diversity when compared to the core area. Pronounced fixed heterozygosity was found in P. alpicola s.str., supporting its allopolyploid origin. In accordance with assumptions, genotypic variability was significantly higher in sexually reproducing diploid and diploid-polyploid taxa than in apomictic P. alpicola s.str.
