Results of the Third High Protein-High Lysine Wheat Observation Nursery Grown in 1977

This is the third report of results from a high protein-high lysine (HP-HL) wheat observation nursery organized in 1974 by the Nebraska Agricultural Experiment Station and the Science and Education Administration, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. Advanced experimental lines distributed to breeders and cooperators in the 3rd HP-HL nursery were selected from numerous hybrid combinations of both spring and winter types. All exhibited elevated protein and/or lysine in nursery trials in Nebraska or Arizona

Results of the Second High Protein-High Lysine Wheat Observation Nursery Grown in 1976

This is the second report of results from a high protein-high lysine (HP-HL) observation nursery organized in 1974 by the Nebraska Agricultural Experiment Station and the Science and Education Administration, U. S. Department of Agriculture, under a contract with the Agency for International Development, U. S. Department of State. Primary objectives of this nursery are to: (1) Systematically provide breeders and cooperators with superior genetic germplasm for elevated levels of protein and/or lysine. (2) Test the degree of expression of the high protein and high lysine traits in a diverse array of environments. Funding from USAID has permitted the Nebraska wheat program to establish breeding nurseries at Lincoln, Nebraska, for evaluation of winter genotypes and at Yuma, Arizona, for both spring and winter wheats. Advanced experimental lines distributed to breeders and cooperators in the 2nd HP-HL nursery were selected from numerous hybrid combinations of both spring and winter types. All exhibited elevated protein and/or elevated lysine in nursery trials at Nebraska and Arizona. The lines were screened for growth habit at Nebraska, and were assigned to the designated spring or winter sections of the 2nd HP-HL nursery

Results of the Fourth International Winter Wheat Performance Nursery

The Fourth International Winter Wheat Performance Nursery was grown in 1972 at 44 sites in 27 countries. Data were reported from 40 sites. The 30 cultivars grown in the nursery included 15 new entries. Twenty-nine cultivars were winter wheats; one was a spring wheat. Data are reported on grain yield, test weight, plant maturity, plant height, lodging, shattering, winter survival, 1000 kernel weight, frost damage, plant diseases, grain protein and lysine content. Two-year mean data summaries also are reported. Supplemental nursery management information is reported for each nursery site

Results of the Sixth International Winter Wheat Performance Nursery Grown in 1974

This is the sixth 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
