C. Report of the Committee on Genetic Stocks

T. OMURA, Convener

In our Rice Genetic Stock Center at Kyushu University, we did not receive any seed sample and information during last one year except for a few lines with complementary genes for photoperiod sensitivity contributed by Dr. H. I. Oka. We would like to request again all the members of RGC to provide us seeds of new genetic stocks with the related information. Especially, the RGC members who reported new genes are requested to send us the stock seeds. Your kind cooperation will be highly appreciated. We are now planning to publish a list of marker gene stocks in a future issue of RGN after the numbering system of rice chromosome is established.
