In the progeny of desynaptic diploids, one desynaptic tetroploid is obtained. A comparative study of the PMC meiosis in the desynaptic diploids and the desynaptic tetraploid is carried out. The desynaptic tetraploid is characterised by high univalent and low multivalent frequency. The mean chiasma frequency in the desynaptic tetraploid is only slightly higher than that in normal diploid plants and nearly twice the maximum frequency observed for the desynaptic diploids. Different possibilities for the origin of the desynaptic tetraploid and its genetic constitution are discussed
