Even though, almost one quarter of populations harboured 2-5 cytotypes. Quite surprisingly, 3x cytotype prevailed in some mixed-ploidy populations, which was the first evidence of such phenomenon in plant system with exclusively sexual reproduction. The theory of maintenance of cytotype co-existence based not only on establishment of pre- and post- zygotic barriers, but even on free mating inetractions was suggested.
