Detailed analyses of the chromosome meiotic behaviour and of mitotic metaphase chromosomes (2n = 32), as well as stainability studies of pollen fertility, were carried out in order to determine the cytological status of amphidiploid Trifolium repens L. (Dutch white clover). In amphidiploid (allotetraploid) Trifolium repens L., diploid-like meiotic behaviour of chromosomes was found, with no multivalent formation, and a normal karyotype with a single pair of chromosome having a secondary constriction was observed. These characteristics indicate favourable genetic and cytological stability in nature, and high pollen fertility further enhances its usefulness in breeding.
