From crosses between allotriploid plants with genomes AAC and diploid O. sativa plants (AA), 12 types of alien addition lines with single C-genome chromosome were distinguished on the basis of morphological characteristics of the addition type plants. Of the 12 chromosomes of O. officinalis (WOO65), 6 apparently were homeologous with those of O. sativa in varying degrees. The occurrence of many univalents in the PMCs [pollen mother cells] of 2 alien addition lines, G and J, suggests that 2 chromosomes of O. officinalis (WOO65) have genes which disturb the pairing of homologous sativa chromosomes.
