INTRODUCTION
The 2005 Uniform Early Oat Performance Nursery was grown at 10 locations in 8 states.
The "Comments on Growing Conditions" provide some insight on the growing
conditions of the reporting locations. The 2005 nursery average yield was 129.3 bu/A,
similar to last year's nursery.  The highest yielding location for 2005 was Ames, Iowa
with 168.1 bu/A.  The lowest location yield was at Waseca, Minnesota (54.6 bu/A).  Three
locations were included in tables but not in a number of averages due to high crown
rust differential effects or high coefficient of variation.  These locations were at Waseca
Minnesota (54.6 bu/A), East Lansing, Michigan (62.9 bu/A) and Rosemount, Minnesota
(67.5 bu/A).  Both Minnesota locations were excluded from calculations because of high
differential crown rust effects.
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 2005 UEOPN".  These values were either supplied by the
cooperator, or the individual plot data were submitted and the values computed.  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 duhuller.  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 new feature added to the report this year is a list of recently released cultivars
(Appendix D) including state or program of origin, assigned name, experimental line
number in testing, nurseries tested in, and pedigree.  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 Laurie Herrin, USDA Cereal Crops Research Unit, Madison, Wisconsin, for
analyses of groat protein, beta-glucan, and oil percentages.
