Several individuals and organizations have already indicated their willingness to cooperate on this project. For example: the USDA in cooperation with Oregon State College (R. J. Metzger) would maintain known wheat genetic stocks for bunt (Tilletia sp) resistance; the University of Kyoto (K. Yamashita) would maintain stocks of Aegilops species; Kansas Agric. Expt. Sta. (E. G. Heyne), wheat strains resistant to leaf rust; Canada Dept. of Agric. Res. Lab., Winnipeg (R.G.Anderson), wheat strains resistant to stem rust; Cambridge University (R.Riley), awns in wheat; USDA in cooperation with the University of Missouri(E. R. Sears), Chinese aneuploids; and Nebraska Agric. Expt. Sta. (J. W. Schmidt), some of the genetic stocks not designated.

"At the present, only stocks of known genetic material on which published information is available will be maintained. This will result in a modest beginning as most of the stocks used in earlier studies probably are no longer available. We also are interested in maintaining viable stocks of wheat species and related genera. This is to be a maintenance program only and those requesting seed should expect to obtain no more than 10 to 15 viable seeds. We plan to list through FAO, the Wheat Information Service, and the Wheat Newsletter those individuals who will maintain wheat genetic stocks and the material they have available.

"If you are interested in this program of maintenance of wheat genetic stocks and related species, express your opinion and suggestions to me and also indicate if you would help in maintaining stock of any particular group of genetic characters in wheat or related species.

"Genetic studies involving disease reaction also are ooncerned with the preservation of the pathogenic organisms used in the studies. This phase of the problem needs further study.

"The problem of nomenclature and symbolization needs attention, but at the present, all of us should adhere to the general rules adopted at the Tenth International Genetics Congress. Perhaps later they may be clarified as to use in wheat.

"The international committee consists of R. G. Anderson, Canada; R. Riley, England; K. Yamashita, Japan; and E. G. Heyne, U.S.A.

Each of us could write such a letter to wheat genetic workers in our area and assemble the comments. If this suggestion does not seem feasible, I would appreciate your suggestions for a different or better approach to our assignment.

It appears that the National Seed Storage Laboratory at Fort Collins, Colorado will store a small sample of each stock. If they accept the seed, it becomes their property and will be handled under their rules and regulations. This may raise some objections from those outside the United States. However, I look at this storage only as a duplicate one on which only an occasional request will be made.
