• We investigated the meiotic chromosome behavior of two ginger strains, 'Sanshu' and 'Philippine'. Most of the chromosome associations found in PMCs (pollen mother cells) at metaphase I were normal (80% PMCs with 11_<II>) except for two kinds of association, 10_<II>+2_I and 9_<II>+4_I. At anaphase I to telophase I, PMCs with one to four laggards were observed in both strains, of which the 'Philippine' strain displayed a higher frequency. At anaphase I, one to three chromosome bridges with fragments were observed in both strains. At anaphase II, approximately equal frequencies of PMCs with one to two bridges were recorded in both strains. The frequency of PMCs with fragments, observed at anaphase I and II in both strains, was significantly higher in 'Sanshu' than in 'Philippine'. On the basis of these results, we suggest that the meiotic irregularities of the two strains are mainly brought about by inversions, and that the sterility of ginger is caused by chromosome structural hybridity.
