VARIETAL TRIALS OF WHEAT - 1969 Successful crop production depends to a considerable extent on selecting the best varieties for a particular farm. To provide a basis for the selection of varieties, the Minnesota Agricultural Experiment Station compares varieties in trial plots. These trials are conducted on the Agricultural Experiment Stations at St. Paul, Rosemount, Waseca, Lamberton, Morris, Crookston, and Grand Rapids, and on farmers' fields. Recommended varieties, important old varieties, and new varieties are grown in replicated plots at each location. These plots are handled so that the factors affecting yield and other characteristics are as nearly the same for all varieties at each location as is possible. On the basis of results from these comparative trials, the list of varieties recommended for use in Minnesota is revised each year by the Experiment Station Crop Variety Review Committee. Data for varieties not included in all trials averaged within a table have been adjusted so that averages of varieties tested for different numbers of years can be compared directly. For most crops, varieties are arranged in order of "recommended varieties", "varieties not adequately tested," and "other varieties;" and in alphabetical order within each group. Recommended varieties have performed better than other varieties in important characteristics in comparative tests. A variety usually is not eligible for recommendation until it has been tested in Minnesota for at least 3 years. New varieties developed in other states or countries but not sufficiently evaluated here are listed as "not adequately tested." Information now available regarding these varieties is presented but no conclusions are drawn regarding their suitability under Minnesota conditions. Varieties listed in the "other varieties" category are usually inferior in one or more characteristics, as demonstrated in comparative tests. The use of certified seed of recommended varieties is recommended. Varieties eligible for certification by the Min nesota Crop Improvement Association include varieties recommended by the Minnesota Agricultural Experiment Station, certain new varieties not adequately tested in Minnesota, and certain nonrecommended varieties. Certification does not imply recommendation of a variety. Registered and certified seed of most varieties described in this report can be purchased from seed dealers or from growers listed in the Minnesota Registered and Certified Seed Directory for 1970 Planting. This annual publication can be obtained without charge from the Minnesota Crop Improvement Association, St. Paul, Minnesota 55101, or from county extension agents' offices. Author of this publication is: spring and winter wheat, R. E. Heiner. Extension agronomists H. J.Otto and E. A. Oelke also participated in preparation of this publication. Field work of the variety trials at Waseca, Lamberton,Morris, Crookston, and Grand Rapids was supervised by W.E. Lueschen, W. W. Nelson, D. D. Warnes, J. R. Lofgren,and R. H. Anderson, respectively.
