Male meiosis in natural decosaploid (22x) Morus nigra L. has been found regular with good pollen fertility. This is the clear indication of cytological stability attained by the polyploid to maintain its level. Young pollen mother cells showed 1-4 nucleoli. The frequency of bivalents was more than that of multivalents and univalents occur rarely which clearly indicates the auto-allopolyploid nature of the taxon. The normal meiotic behaviour of this high polyploid is discussed in relation to its evolution.
