Cytology of diploid and induced autotetl'aploid of ginger (Zingiber officinale Rosc.) was studied. The diploid (2n=22) showed one or two associations offour chromosomes at first metaphase. The tetraploid formed a high frequency of quadrivalents at first metaphase. Both showed bridge-fragment configurations at first anaphase. Pol1en fertility was 13% in the diploid and 85% in the tetraploid.
