The major task of the Committee is to enhance cooperation among rice geneticists on standardization of gene symbols and linkage groups. Proposals for rules of gene symbolization based on the international rules adopted by International Congress of Genetics (ICG) and International Rice Commission (IRC) and a list of recommended gene symbols was presented in Rice Genetics Newsletter 1 (p.2-15). Some additional rules seem to be necessary. In this volume, a supplement list of gene symbols and of marker genes belonging to different linkage groups is presented. We hope the members will follow the rules of gene symbolization while assigning the symbols for the newly identified genes and consult with the convenor of this committee before publishing the gene symbol.
This procedurd will help the investigator in choosing a reasonable and permanent gene symbol for his new mutant and will protect his priority.

2. Report of the Committee on Genetic Stocks, T. OmuraThe activites of this Committee aim at compiling and keeping records on rice genetic stocks available in different laboratories. This should facilitate the exchange of genetic stocks between rice geneticists. The Committee members are: Drs. T. Omura (convenor), T.T. Chang (IRRI), N. Iwata (Japan), K. Miezan (Ivory Coast), and S.D. Sharma (India).
We request all members of the RGC to send us the list of genetic stocks available with them. These should include gene markers stocks, spontaneous and induced mutants, chromosomal alterations, breeding lines with special characteristics, and stocks of wild species. Please provide us the information on the origin, source of variation, and references if any. We will appreciate receiving reprints of your publications dealing with these variants. We also appreciate receiving your correspondence regarding the exchange of seed stocks, particularly for the purpose of allelism test. Please address correspondence to any member of the Committee.
A "List of Genes and Genetic Stocks" was given in RGN Vol.1. A supplement to this list is given in this volume. In addition, lists of diploid lines induced by anther culture at Hokkaido University, Japan and of wild-rice stocks available in Japan are also included. The laboratories maintaining these stocks are indicated by a code. References to respective stocks are numbered and given in the chapter that follows. We are indebted to Dr. T. Kinoshita for cooperation in making the List of genes and genetic stocks.
