Citation: Edwards, M.C. 2008. 2007 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 6 days later than the 30-year average, while average heading date was only 1 day later than the average. Average yield (4655 kg/ha or 86.5 bu/a) was above the 30-year average, but well below the 30 year high of 2004. Test weight was close to that of the 30 year average. Average plant height was 79.1 cm – less than the 30 year average, but not as short as last year.
Technical Abstract: Nine locations contributed useable data for this year's report. The reader is referred to the "Nursery Conditions" section immediately following this summary for other comments concerning specific locations. Average planting date was May 3rd, 6 days later than the 30-year average, while average heading date was only one day later than the average. The average planting date was nine days later than last year. Heading date (June 26th) was six days later than last year. Average yield (4655 kg/ha or 86.5 bu/a) was above the 30-year average, but well below the 30 year high of 2004 and also below last year’s average. Entries with the best yields were M133, 2ND21867, 6B03-4478, M124, and SR417. Five stations reported test weight; the average of 61.1 kg/hl was lower than that of last year and not far from the 30 year average (60.9). The greatest test weights were recorded for 2ND22182, Pinnacle, 2ND21867, Conlon, and M133. Lodging data were reported from three locations, Bottineau, Carrington, and Osnabrock. The entries with the least lodging were 2ND22182, 2ND21867, Pinnacle, ND20666, and ND20448. Average plant height was 79.1 cm – less than the 30 year average, but not as short as last year. Shortest entries were ND22421, 2ND22182, 2ND21867, ND20666, and SR410. Kernel plumpness data were reported from Kernen, 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 (net blotch, scald, spot blotch).
