Reference: Tsai, K-H. 1991. (RGN 8, Res. note)

II. List of gene symbols

Rice genes published hitherto are listed alphabetically. As for the unautho- lized gene symbols which are marked with asterisk, prompt registration to the convener is expected in accordance with rule 7 (see RGN 3: 4-5).

Coordination of gene symbolizations for heading time and other characters has been discussed in the small group. Toward the integration of different RFLP maps, two groups from Japan and U.S.A. have initiated a cooperative research by exchanging 70-80 kinds of probes.
