Citation: Edwards, M.C. 2007. 2006 Mississippi Valley uniform regional barley nursery. Mississippi Valley Uniform Regional Barley Nursery Report. Interpretive Summary: This report represents a compilation of data contributed by participating barley breeders located throughout the growing region. With cooperators in 7 states and Canada, this nursery serves as one of the primary means of evaluation for the development of malting barley varieties adapted to this region of the country. Virtually all of the 6-row barley used for malting in the U.S. is produced in the upper midwest, and all commercial varieties grown in this region are evaluated in this nursery prior to release. The number of locations contributing data varies each year with the success (or failure) of the nursery in a given location. Nine locations contributed useable data for this year's report. Specific growing conditions for each location are described as well as are detailed agronomic data for each entry in the nursery. Average planting date was 3 days earlier than the 30-year average, while average heading date was about 5 days earlier than the average. Average yield (5191 kg/ha or 96.5 bu/a) was well above the 30-year average, but well below the 30 year high of 2004. Test weight was better than that of last year. Average plant height was 76.1 cm, which is quite a bit shorter than the 30 year average.
Technical Abstract: Nine locations contributed useable data for this year's report. The substitution of Osnabrock for Langdon continues (about 12 miles east). The reader is referred to the "Nursery Conditions" section immediately following this summary for other comments concerning specific locations. Average planting date was 3 days earlier than the 30-year average, while average heading date was about 5 days earlier than the average. The average planting date of April 24th was one day earlier than last year. Heading date (June 20th) was seven days earlier than last year. Average yield (5191 kg/ha or 96.5 bu/a) was well above the 30-year average, but well below the 30 year high of 2004. Entries with the best yields were M126, 2ND21867, 2ND21863, ND21306, and SR410. Three stations reported test weight; the average of 63.2 kg/hl was better than that of last year. The greatest test weights were recorded for 2ND21867, Conlon, 2ND21863, Lacey, and ND21306. Lodging data were reported from only two locations, Carrington and Osnabrock. The entries with the least lodging were ND20508, 2ND22927, ND20666, 2ND21863 and 2ND22996. The reader should remember that 0% lodging was entered for all entries in 1996 due to a lack of data. Thus, the 10-year averages were still somewhat skewed by the 1996 data last year. This year, the 1996 data dropped off and no longer affects the averages. Average plant height was 76.1 cm, which is quite a bit shorter than the 30 year average. Shortest entries were ND20666, 2ND21867, M126, ND21532, and M125. Kernel plumpness data were reported from Hamiota (Brandon) and Sidney. Please refer to Table 18 for further information. Disease data from the Cereal Research Centre in Winnipeg are posted in Table 19. Other disease data appear in Tables 20 and 21 (from Brandon).
