New members of the Committee on Genetic Stocks have been elected in the meeting of the Coordinating Committee of Rice Genetics Cooperative held on May 18, 1990 at IRRI, as follows: Iwata (convener, Japan), A. Ghesquiere (France), H. Satoh (Japan), S. D. Sharma (India), and D. A. Vaughan (IRRI). On behalf of the newly appointed committee members, we wish to express our sincere gratitude to outgoing members: T. T. Chang, K. Miezan and T. Omura (former convener) for their service during the term from 1985 to 1990.
Since the problem of numbering system of rice chromosomes has been settled during the 2nd International Rice Genetics Symposium, we will present lists of primary trisomics and reciprocal translocation lines arranged according to the new numbering system in this volume. We also present a list of recent additions to wild rice germplasm conserved at IRRI (by D. A. Vaughan) and a brief report on Rice Germplasm Conservation Workshop held in May at IRRI (by T. T. Chang).
We will compile and present the list of marker-gene stocks in future issues of RGN, although some genes still remain unsettled regarding their symbolization, nomenclature and allelic relation. For completing the list, we appreciate receiving information on marker-gene stocks maintained by the RGC members. We also plan to make a survey of genetic stocks and lines with chromosomal changes kept by different research units through inquiry to individual scientists. We request kind cooperation of all RGC members concerned.
We also request all RGC members to contribute a share of seeds of new genetic stocks, particularly of those reported in RGC, to Rice Genetic Stock Center, either the convener's laboratory at Kyushu University (code KY, given below) or at IRRI. If received, we present a list of receipts in this report.
