More than 600 different commercial corn hybrids were offered for sale in South Dakota during 1944 and 1945. The task of accurately measuring the performance of all these hybrids is neither practical nor desirable. During the past several years, the Agronomy Department of the South Dakota Agricultural Experiment Station has been conducting performance tests with a large number of commercial hybrids, publishing annually the yields, moisture contents, and other characteristics which influence farmers in their choice of hybrid seed corn. In this way a great deal of information concerning specific hybrids has become generally available. During 1945, changes were made in the method of selecting the entries for the tests, and it is believed that the results presented in this circular represent the performance of the most important hybrids being grown in South Dakota. It should be emphasized that there are many hybrids which have performed well in South Dakota and that the top hybrid in any district for any one year is not necessarily the best one. Long-time averages are the best indication of the performance of a hybrid, and as these tests are continued their results will 'become more valuable. Used with discretion, these data will provide readers with valuable information on the production, sale, and purchase of hybrid corn.
