Cytological examination of anther-culture-derived plants of rice showed that the regenerants were predominantly diploids and haploids. Haploid meiosis indicated that the earlier hypothesis of rice being an ancient polyploid is unlikely. Diploids generally were normal and fertile. The low frequency of polyploids (1.5%) probably was due to rapid regeneration of plants from short term callus cultures.
