| INTRODUCTION | |||||||||
| The 2008 Uniform Midseason Oat Performance Nursery was grown at 18 locations in 10 | |||||||||
| 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 out of the range of adaptation of oat entries in this nursery. | |||||||||
| The 2008 nursery mean yield of 117.0 bu/A was 6.4 bu/A higher than the 2007 mean yield of | |||||||||
| 110.5 bu/A. Fargo, ND was the highest yielding location in 2008 with a location mean of 159.2 | |||||||||
| bu/A. The lowest yielding location was Urbana, IL, with a mean of 62.8 bu/A. This location had | |||||||||
| a severe incidence of BYDV and moisture stress. If this location is omitted, the overall nursery | |||||||||
| average increases to 121.3 bu/A (Table 5A). | |||||||||
| The highest yielding entry was ND030365, as it was also in the 2007 UMOPN, followed by two | |||||||||
| other North Dakota entries, ND021612 and ND020965, and the Wisconsin entry WIX8791-1. | |||||||||
| ND030365 also had the highest groat yield based on the nine locations that submitted grain | |||||||||
| samples (Appendix B), while WIX8791-1 moved up to second highest based on its good groat | |||||||||
| percent. | |||||||||
| 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 | |||||||||
| 2007 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 | |||||||||
| fluorescence spectrometry. | |||||||||
| 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/Avena/UE-MOPN.html). | |||||||||
| We wish to thank Mitchell Wise and Laurie Herrin, USDA Cereal Crops Research Unit, Madison, | |||||||||
| WI, for analysesof groat protein, beta-glucan, and oil percentages. | |||||||||
