Abstract

This is the eighth report of results from an International Winter Wheat Performance Nursery (IWWPN) organized in 1968 by the Nebraska Agricultural Experiment Station and the Science and Education Administration (SEA), 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 and stability of winter wheat cultivars in a range of latitudes, daylengths, fertility conditions, water management regimes, and disease complexes; (2) identify superior winter cultivars 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, and (4) provide a vehicle for exchange of germplasm and research cooperation throughout the major winter wheat producing areas of the world.
