Winter Wheat Cultivar Performance In An International Array Of Environments, J. E. Stroike, V. A. Johnson

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The International Winter Wheat Performance Nursery organized in 1968 by the Nebraska Agricultural Experiment Station in cooperation with the Agricultural Research Service, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State, has presented a unique opportunity to measure the performance and stability of 28 winter wheat cultivars over an international array of environments. Computations of three parameters for yield, selected agronomic traits, and grain protein and lysine were made from nursery data recorded in 1969 and 1970.

The Second International Winter Wheat Performance Nursery was grown in 1970 at 38 sites in 23 countries. Four of the sites were in the southern hemisphere. Data were reported from 36 sites. The same 30 varieties evaluated in the First International Winter Wheat Performance Nursery were grown in this Second International Winter Wheat Performance Nursery. Twenty-eight varieties were winter wheats; two were spring wheats. Data on grain yield, test weight, maturity, plant height, lodging, shattering, winter survival, diseases, grain protein content and lysine content for 1970 are reported. Two-year mean data summaries also are reported.
