Memorandum
The numbering system of rice chromosomes adopted on the basis of agreement at the 2nd International Rice Genetics Sumposium (May 1990, IRRI) is presented in RGN 7 (1990, p.13), in comparison with karyotype numbers, Nishimura's numbers and linkage groups. The numbering of linkage groups is changed to follow the corresponding number of chromosomes.
