KIHARA MEMORIAL
INTERNATIONAL SYMPOSIUM ON CYTOPLASMIC ENGINEERING IN WHEAT


More than eighty wheat researchers from nine countries had attended to Kihara Memorial
International Symposium on Cytoplasmic Engineering in Wheat (ISCEW) held on July 3-6, 1991 at Hokkaido University, Sapporo, Japan, under chairmanships of Drs. T. Kinoshita (Hokkaido Univ.) and T. Sasakuma (Kihara Inst.). The Symposium was an informative opportunity to discuss the comprehensive subjects of cytoplasmic inheritance, evolution, and its utilization for plant breeding.

The followings are the program of the Symposium, which include three special lectures and six sessions, the field trip to wheat research fields, in addition to Dr. H. Kihara memorial banquet in which a document film on his career was presented. The sessions were organized under free atmosphere with hot discussions. The proceedings will be published in the end of 1991 in the special issue of SEIKEN ZIHO.
