A karyotype study was made on Hypericum perforatum using plants differentiated in vitro with different ploidy level. The chromosomes of this species are small, morphologically similar, median and submedian. In the basic chromosome set the most distinguishable is chromosome number 1 which was subjected to detail analysis. It was found that there are two types of this chromosome which contribute differentially in diploid, triploid and tetraploid plants.
