Summary

The meiosis of a 36-chromosome plant ofSolanum demissum of undoubted polyhaploid origin is described. The significance of the type of pairing is discussed and the probable genomic constitution ofABB 1 for the polyhaploid andAABB 1B1 forS. demissum is proposed. Cytological studies of hybrids betweenS. demissum and recently described Demissa hexaploids show the first instance of gross meiotic unbalance in species hybrids of tuberousSolanums, and give further indication of genomic differentiation in the group Demissa. From an analysis of this behaviour, supported by the observations on polyhaploidS. demissum, a tentative scheme has been drawn up giving the genomic constitution of the hexaploids. From it their interrelationships are revealed and their possible origin discussed.
