✦ Synopsis

During the past three decades, Nishimura's reciprocal translocation lines of rice have been used in rice cytogenetics to locate genes on chromosomes, to number extra chromosomes of trisomic series and to associate individual linkage groups with specific chromosomes. In this report, we present our identification of the chromosomes involved in 11 of Nishimura's translocation lines using both meiotic pachytene and mitotic prometaphase chromosome analysis. In addition, the numbering of the 12 linkage groups suggested by Nagao and Takahashi, and modified later by many workers, has been revised to agree with the numbering of the identified chromosomes.
