In this issue, we present the lists of marker stocks maintained in IRRI and Hokkaido University. We also present lists of isogenic lines maintained in National Institute of Agrobiological Resources of Japan and National Agricultural Research Center of Japan. We will continue to present the list of available marker gene stocks in future issues of RGN. We request kind cooperation of all RGC members.
We also request all RGC members to contribute a share of seeds of new genetic stocks, particularly of those reported in RGN, to the Rice Genetic Stock Center in Iwata's laboratory at Kyushu University (Faculty of Agriculture, Hakozaki, Fukuoka, 812 Japan) or to Dr. G. S. Khush of the IRRI (P. O. Box 933, 1099 Manila, Philippines). If received, the information will be presented in this report.
