Small grain varieties are evaluated each year by University of Arizona personnel. The purpose of these tests is to characterize varieties in terms of yield and other attributes. Variety performance varies greatly from year to year and several site-years are necessary to adequately characterize the yield potential of a variety . A summary of small grain variety trials conducted by the
University of Arizona can http://ag.arizona.edu/pubs/crops/az1265.pdf. be found online at
Small grain varieties were tested as part of the on-going effort to assess variety productivity and characteristics.
Barley, durum, and wheat commercial cultivars and experimental lines were tested. The purpose of these tests is to characterize varieties in terms of yield potential, relative maturity, quality, and other characteristics. Small plot variety trials do not substitute for localized on-farm testing of new varieties. Varieties are known to differ in their response to specific management regimes and weather conditions. A summary of small grain variety trials conducted by the University of Arizona is available from your local Cooperative Extension office or online at http://ag.arizona.edu/pubs/crops/az1265.pdf
.
Barley, durum, and wheat varieties were evaluated at the following locations: Maricopa by the University of
Arizona, Arizona City by Arizona Plant Breeders, and Yuma by WestBred. Data from a location at Tonopah by
World Wide Wheat was not collected due to a combination of herbicide damage and apparent sodium damage. The seed was planted in 20 ft rows with a cone planter in seven rows spaced 7 inches apart except at Maricopa where 10 rows were planted 7.56 inches apart. The seeding rate was approximately 100 lbs/acre for durum and wheat varieties and 85 lbs/acre for barley varieties. The experimental design was a randomized complete block with 3-4 replications, and 13 barley, 20 durum, and 10 wheat entries. Growing conditions at each site are listed in Table 1.
The following data was collected, but not all data was collected for all crops at all locations: grain yield, test weight, seed weight, plant height, lodging, heading, physiological maturity, grain protein, and HVAC. Grain was harvested with small plot combines and yields are expressed on an “as is” moisture basis. Test weight was calculated from the weight of 1 pint of grain. Seed weight was determined from 200 seed. HVAC was determined from 10 g of seed.
Grain protein was determined from total N multiplied by 5.7 for durum and wheat, and expressed on a 12% moisture basis. Physiological maturity is defined as when the glumes turn brown. Abbreviations for the sources of varieties are: APB = Arizona Plant Breeders, UA = University of Arizona, WB = Western Plant Breeders, WWW = World
Wide Wheat, UC = University of California.

Yield and plant characteristics of the varieties are presented for the various locations in Tables 2-7 and a summary of the grain yields at all locations is presented in Table 8. This year was characterized by very cold weather in January.
Several locations and years are needed to accurately assess variety performance. The results of this trial are most useful when combined with data from previous years. A summary of small grain variety trials conducted by the
University of Arizona can be found online at http://ag.arizona.edu/pubs/crops/az1265.pdf
.
Financial support for this project was received from the Arizona Grain Research and Promotion Council and the
Arizona Crop Improvement Association. I wish to thank Zewdie Abate and Donny Gray of Westbred for conducting the trials in Yuma and Oly Cantu and Al Carleton for conducting the trials in Arizona City (APB). The technical assistance of Mary Comeau, Richard Simer, and Glenda Simer is greatly appreciated.
