Of 3, 746 rice varieties and strains collected from all over the world, 2, 842 (75.87%), 900 (24.03%), 2 (0.05%) and 2 (0.05%) showed J-, I-, O- and M-type zymograms of acid phosphatase, respectively. The gene symbols Acp19 Acp2Nul, Acp1-4 Acp2Fa, Acp1Nul Acp2Fa and Acp1Nul Acp2Nul were given for the J-, I-, O- and M-type zymograms, respectively, following the format described by Pai et al. (1975). Hereafter, however, in this paper the authors mainly used only the gene symbol of the Acp1 except the M-type zymogram, because the Acp1 locus was closely linked with Acp2 as described by Pai et al. (1975). F2 generations obtained from the F1 between the I- and J-types gave a good fit to a 1:2:1 ratio suggesting that these zymograms were controlled by Acp1 locus which carried two codominant alleles. The O-type zymogram was spontaneously induced mutant from the I-type, and controlled by a single recessive silent allele, Acp1Nul. The M-type was artificially induced mutant from the J-type, and governed by double recessive alleles, Acp1Nul Acp2Nul. From the results described above, all varieties and strains of the sativa rice plants were divided into either the genotypes Acp19/Acp19 or Acp1-4/Acp1-4. The gene Acp1-4 is distributed in the low latitude area with high frequencies, while the gene Acp19 predominates in the high latitude area.
