The land lying fallow and modifications to the use of agricultural lands cause changes in biodiversity. The slow process of secondary succession causes an increase of their genetic variability. The aim of the presented work was to estimate the level of genetic variation among Galium aparine genotypes from two different fallow lands. The assessment of genetic diversity was based on the ISSR markers. The genetic distance matrix was calculated based on the Dice’a formula. The value of similarity index ranged from 0.755 to 1.00. The research showed that the analysed genotypes were characterised by quite a low level of genetic variability. The common grouping of genotypes collected from two habitats can attest to the fact that the type of habitat, soil and long-term land lying fallow can influence Galium aparine variability.
