Stroike, J.E., Johnson, V.A., Schmidt, J.W., Mattern, P.J. and Wilhelmi, K.D. (1973) Results of the third international winter wheat performance nursery (Research bulletin No. 256)
This is the third 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 varieties in 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, and (3) test the degree of expression and stability of the high protein and high lysine traits in an array of environments.
