We investigate if known cytotypes of Vicia cracca from the native and invasive range differ in their ability to adapt to environmental variation. To do this, we grew plants of both cytotypes from the native and invasive range in a common garden and exposed half of the plants to experimental shading to simulate environmental variation potentially occurring at the localities of the species. The study confirmed previous expectation that only polyploid plants occur in the invasive range. The study, however, did not support the expectation that the tetraploids would be superior to the diploids from the native range or have better ability to cope with shading. The performance and plasticity of tetraploids from the invasive range was in most cases different from the European tetraploids and differed between the two areas in the invasive range. This may suggest that the tetraploids underwent strong postinvasive evolution and have adapted in different ways to the specific condition of the different parts of the invaded area. Alternatively, it may indicate that the invasive range was created by colonizers from different areas possessing distinct adaptations.
