Abstract

                                At the outbreak of war the Russian Agricultural Research Stations devoted themselves to the problem of maximum production of food and raw materials in the U. S. S. R. The potato, yielding as it does the highest amount of human food per acre of any crop in common cultivation, naturally figured prominently in the plan. The necessary large increase in potato acreage raised several serious problems in regard to the supply of seed tubers, and the way in which these difficulties are being met is an interesting example of the work of Russian scien- tists during the war.
