Weed species Asclepias syriaca L. (common milkweed) originating from the northern parts of central and northeastern United States and Canada, in Europe came at the beginning of the 19th century and it arrived to Serbia from neighboring Hungary. From north part of the country, it spread fast and distributing along roads and railways, as well as along rivers, through Subotica and Deliblato sands finally invaded south of Vojvodina. The aim of this study was to determine which types of land is the most suitable for this type of weed in order to predict the possibility of its further expansion. Coordinates of the registered A. syriaca populations were introduced into the digital map, and the analysis of its distribution in different soil types was accomplished. From 1250 recorded populations of A. syriaca in Bačka, the highest percentage was recorded on chernozem 50.88%, i.e. 33.44% and 5.12% in fluvisol. alluvial land and humogley, respectively. The lowest number of A. syriaca population was recorded in rendzina, regosol and pseudogley soil type. The correlation coef- ficient between the percentage of A. syriaca population on different soil types and areas under these soil types indicates a statistically significant positive correlation between these two variables. The impact of soil types to the distribution of A. syriaca proved to be insignificant since it was established in almost all soil types of Vojvodina.
