INTRODUCTION	INTRODUCTION
The 2006 Uniform Midseason Oat Performance Nursery was grown at 17 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.  Data from Urbana, Illinois are presented but not included
in yield and yield parameter averages because of severe barley yellow dwarf virus effects.
The 2006 nursery mean yield of 116.6 bu/A was lower than the 2005 mean yield of 119.9
bu/A, and much lower than the 2004 mean yield of 133.6 bu/A.   West Lafayette, Indiana
(150.7 bu/A) recorded the highest overall average yield with Fargo, North Dakota second
at 139.0 bu/A.  The lowest average nursery yields were from Ithaca, New York (82.1 bu/A),
Rosemount, Minnesota (84.1 bu/A) and Urbana, Illinois (86.6 bu/A).
The highest yielding entry was SD 030888 with a mean yield of 126.1 bu/A. It was also second
highest in test weight; however, it was lowest in the nursery in groat percent as determined in these
tests.   Following close behind in yield were entries WIX8718-1 at 125.0 bu/A and ND 020965
with 124.2 bu/A.  It was the first year that these lines were tested in the UMOPN.  The lowest yielding
entries were the long-term checks, Gopher and Clintland 64, with mean yields of 97.1 and
103.2 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 2006 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 reported in Table 11 were determined by dehulling a 50-gram sample
with a Codema oat dehuller. The groat protein percent values in Table 12 and groat oil
percent values in Table 15 were run on the Infratec 1255 Food and Feed Analyzer (whole
seeds using near-infrared transmittance).  A standard regression for protein was calculated
using a sub-set of samples run on the Leco FP-428 nitrogen combustion apparatus.  The oil
regression was based on NMR analyses.  Beta-glucan values reported in Table 17 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 on
page 4.  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, WI, for  analyses
of groat protein, beta-glucan, and oil percentages.
