Abstract

Prior to 1960. a number of scientists who had had occasion to stqdy uniform sets of material such as the International Rust Nursery of the United States Department of Agriculture. noticed that, apart from disease reaction. some varieties appear to be much wider adapted than others. Beginning in 1960, a series of Inter-American Spring Wheat Yield Nurseries have been seeded throughout the wheat growing regions of the hemisphere as well as at a few locations in the Near-EastandAfrica. The results of three of these nurseries have been previously published (1, 2, 3), and the present publication includes the results of the fourth and final of these nurseries and a somewhat more thorough statistical treatment than was previously possible. These nurseries have been designed to furnish definitive, quantitative data concerning the range of adaptation of the major wheat types of the. world under the range of environmental condition!i of the American wheat growing areas
