| INTRODUCTION | |||||||||
| The 2011 Uniform Midseason Oat Performance Nursery was grown at 15 locations in 8 | |||||||||
| states and 3 Canadian provinces. The ‘Comments on Growing Conditions’ provide some | |||||||||
| insight on the growing conditions of the reporting locations. Data from Aberdeen, Idaho, and | |||||||||
| Lacombe, Alberta, are presented but not included in nursery means because their locations | |||||||||
| are generally out of the range of adaptation of oat entries in this nursery. Nurseries were lost at | |||||||||
| Carrington, North Dakota, and Watertown, South Dakota, due to hail and at Fargo, North Dakota, | |||||||||
| due to excess water. The yield data from Ithaca, New York, are presented but are omitted from | |||||||||
| the 2011 nursery yield averages because of a high C.V. due to poor growing conditions. | |||||||||
| The 2011 nursery average yield of 90.0 bu/A was well below the 2010 average yield of 117.7 bu/A. | |||||||||
| The highest yielding location in 2011 was Madison, Wisconsin, with an average yield of 111.5 bu/A. | |||||||||
| The lowest yielding location was Ottawa, Ontario, with an average of 66.4 bu/A due to poor soil | |||||||||
| preparation following prolonged early rains. | |||||||||
| The highest yielding entry was SD090552 with an average yield of 106.9 bu/A followed | |||||||||
| closely by MN09255 at 106.4 bu/A and ND070182 at 105.7 bu/A. Entry SD090552 was also | |||||||||
| highest in test weight among nursery entries and third highest in groat percent. The lowest | |||||||||
| yielding entries were the long-term checks, Gopher and Clintland 64, with mean yields of | |||||||||
| 50.5 and 63.8 bu/A, respectively. | |||||||||
| Coefficient of Variation (CV) and Least Significant Difference (LSD) values for yield are provided | |||||||||
| for each location in Table 5 ‘Average yield (bu/A), yield, and rank at stations reporting the | |||||||||
| 2011 UMOPN’. These values were either supplied by the cooperator or calculated using the | |||||||||
| individual plot data submitted by the cooperator. This information plus the listing of ‘Plot Data’ | |||||||||
| and ‘Comments on Growing Conditions’ at individual locations should help in interpreting the results. | |||||||||
| The groat percentages were determined by dehulling a 50-gram sample with a Codema oat dehuller. | |||||||||
| The protein and oil samples were run on the Infratec 1255 Food and Feed Analyzer (whole seeds | |||||||||
| using near-infrared transmittance). A standard regression for protein was made using a sub-set of | |||||||||
| samples, which was run on the Leco FP-428 nitrogen combustion apparatus. The oil regression | |||||||||
| was based on NMR analyses. Beta-glucan values were determined by chemical analysis using | |||||||||
| the calcofluor fluorescence method. | |||||||||
| A list of recently released cultivars including state or program of origin, assigned name, | |||||||||
| experimental line number in testing, nurseries tested in, and pedigree can be found in | |||||||||
| Appendix C. This list, in addition to being included in the annual nursery reports, is to be | |||||||||
| maintained in an updated fashion on a GrainGenes website: | |||||||||
| (link at http://wheat.pw.usda.gov/GG2/oat.shtml). | |||||||||
| We wish to thank Mitchell Wise and Laurie Herrin, USDA Cereal Crops Research Unit, Madison, | |||||||||
| WI, for analyses of groat protein, beta-glucan, and oil percentages, and Roger Caspers, University | |||||||||
| of Minnesota, for groat percent determinations. | |||||||||
