"Kochia biotypes (Kochia scoparia (L.) Schrad.) resistant to acetolactate synthase (ALS) inhibitors and atrazine were proved at railway junctions in the Czech Republic. Susceptible biotypes were found in several localities in the proximity of railway stations, roads and parking areas, and on arable land with common crop rotation and herbicide use. Ploidy levels of both susceptible and resistant biotypes of kochia were investigated by flow cytometry of vegetative tissues. All examined plants belonged to DNA-diploids, nevertheless, endopolyploidy was detected in all vegetative parts. In leaf tissues, nuclei with 2C DNA content were usually the most abundant group (mean proportion 55.2 %), followed by 4C nuclei (37.6 %) and 8C nuclei (7.2 %).
