摘要: In 7 aneuhaploids of Solanum tuberosum and one clone S. phureja the mechanism unreduced microspore production has been studied. It observed that microspores are produced not only by nuclear restitution at meiosis but also aberrant cytokinesis in meiocyte. The size number nucleoli present young sporad stage give a fairly reliable indication ploidy level type occurred. These two aspects helpful to deduce meiotic events have probably led formation some cases. found triads dyads formed regardless division or restitution, indicating is independent karyokinesis extent. Cytological basis diploid forms potato appears be more complex than it was supposed earlier.
