Stroike, J.E., Johnson, V.A., Schmidt, J.W., and Mattern, P.J. (1971) Results of the first international winter wheat performance nursery (Research Bulletin No. 245)
The International Winter Wheat Performance Nursery was organized by the Nebraska Agricultural Experiment Station and the Agricultural Research Service, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. There has been informal cooperation with the Food and Agriculture Organization, United Nations, and the International Maize and Wheat Improvement Center (CIMMYT), Mexico, D. F. Specific objectives of the nursery are to: (1) Test the adaptation of winter wheat varieties under a range of latitudes, daylengths, fertility conditions, water management and disease complexes (2) Identify superior winter varieties to serve as recipient genotypes for high protein and high lysine genes (3) Test the degree of expression and stability of the high protein and high lysine traits in an array of environments.
