Stroike, J.E., Wilhelmi, K.D., Johnson, V.A., Schmidt, J.W., and Mattern, P.J. (1976) Results of the fifth international winter wheat performance nursery grown in 1973 (Research bulletin No. 276)
This is the fifth report of results from an International Winter Wheat Performance Nursery (IWWPN) organized in 1968 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. The Nursery was designed to (1) test the adaptation of winter wheat cultivars in a range of latitudes, daylengths, fertility conditions, water management, and disease complexes; (2) identify superior winter cultivars to serve as recipient genotypes for high protein and high lysine genes, and (3) test the degree of expression and stability of the high protein and high lysine traits in an array of environments.
