American power at the end of World War II was paramount. The usual image of this might, however, is formed more by the array of military and industrial components of American culture than by something as seemingly mundane as wheat breeding. Nuclear-tipped missiles, airplane and tank factories, engineering prowess, and motivated soldiers are more generally assumed to be the components of military strength, not scientists patiently crossing one strain of wheat with another and searching through the progeny for a better variety. In the direct exercise of military power, of course, the weapon systems and soldiers are the most important elements of power. Armies, however, exist only on the foundation of food supplies that are adequate for both the military personnel and their civilian support force. American strategists in both world wars were acutely aware of the role of agriculture in the projection of military might, and they considerably amplified agriculture’s importance in the aftermath of World War II. Specifically, through a variety of public and private initiatives, wheat breeding and other lines of agricultural science became an integral part of postwar American strategic planning. Put somewhat differently, after 1945, wheat breeding by American scientists became more than just an exercise in the modernization of agriculture. Old motivations for seeking new varieties did not disappear, but new motivations arose to justify expenditures. In addition, American scientists came to do their work not only in the United States for American farmers but overseas for foreign governments. Wheat breeding acquired ideological dimensions more elaborate than simply “the promo tion of progress.” Instead, wheat breeding and other agricultural science became part of the “battle for freedom.” In the process, many countries moved to new relationships with each other and with their own natural resource base. How did wheat breeding get caught up with strategic and national security considerations? It is necessary to follow a somewhat convoluted trail to answer this question, and the story can begin with the status of the United States after the collapse of Germany and Japan in 1945.
