INTRODUCTION
	The 2012 Uniform Midseason Oat Performance Nursery was grown at 17 locations in 9 states
	and 4 Canadian provinces.  Agronomic data collected at Aberdeen, Idaho, and Lacombe, Alberta,
	are presented but not included in the overall nursery averages because these locations are out
	of the range of normal adaptation.  Single rep data from Saskatoon, Saskatchewan, are presented
	in a separate table (Table 25).
	The "Comments on Growing Conditions" provide some insights on performance at the various
	locations.  The 2012 nursery average yield of 105.1 bu/A was above the 2011 nursery average of
	90.0 bu/A but lower than the average in 2010 of 117.7 bu/A.  There was a large variation in yield
	among locations.  A very low yield average at Madison, Wisconsin, of 51.0 bu/A and reduced
	yields and seed quality at several other locations were attributed to hot, dry conditions during
	grain fill.  West Lafayette, Indiana, with the highest yield average of 179.7 bu/A, apparently
	escaped the heat effects due to early planting.  Because of the onset of hot, dry conditions at
	many locations, earlier heading entries in general did better than later heading ones.  A notable
	exception was at Minot, North Dakota, where the latest heading entry was the highest yielding.
	The highest yielding entry was P0216A1-1-45 with an average yield of 127.3 bu/A, but it was also
	among the lowest in groat percent at the 5 locations where seed samples were analyzed.  The
	second highest yielding entry, SD10127 at 123.9 bu/A, also was the highest entry in test weight,
	but it was among the worst in lodging.  The lowest ranking entry in overall yield average was the
	very late heading entry OT2074, but it was the highest yielding entry at Minot, North Dakota.
	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
	2012 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.
	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:

	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.
