In our Rice Genetic Stock Center at Kyushu University, we received seed samples
and attached information from three members of RGC as follows: A total of 69
isogenic reciprocal translocation lines of Taichung 65 from Dr. S. Sato,
Faculty of Agriculture, University of Ryukyus, eight mutants for low amylose
content in the endosperm starch from Dr. M. Nakagahra, national Institute of
Agrobiological Resources, Japan, and a Nepalese native variety showing a low
amylose content from Professor M.H. Heu, College of Agriculture, Seoul National
University at Suweon, Korea. We appreciate their cooperation.
We request all the members of RGC to provide us with information and seeds of new genetic stocks. As soon as a marker gene is reported, please send us a small amount of seeds and related information. Your kind cooperation will be highly appreciated. We are planning to publish a list of marker gene stocks in a future issue of RGN after the numbering system of rice chromosomes is established.
