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. Eight 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 2 days earlier than the 30-year average, while average heading date was about 3 days later than the average. Average yield (4390 kg/ha or 82 bu/a) was well above the 30-year average, but much less than that of last year. Test weight was much better than that of last year. Average plant height was 84.5 cm, which is very close to the 30 year average.

Technical Abstract: Eight 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 2 days earlier than the 30-year average, while average heading date was about three days later than the average. The average planting date of April 25th was two days later than last year. Heading date (June 28th) was three days earlier than last year. Average yield (4390 kg/ha or 82 bu/a) was well above the 30-year average, but much less than that of last year. Entries with the best yields were M121, ND20299, ND20314, Newdale, and 2ND21863. Four stations reported test weight; the average of 61.7 kg/hl was much better than that of last year. The greatest test weights were recorded for Conlon, 2ND21863, 2ND19854, ND19620, and M121. Lodging data were reported from three locations, including Morris, Bottineau, and Hamiota. The five entries with the least lodging were ND20314, Drummond, Stellar, Tradition, and SR403. 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 will still be somewhat skewed by the 1996 data, although next year the 1996 data will drop off and no longer affect the averages. Average plant height was 84.5 cm, which is very close to the 30 year average. Shortest entries were ND19655, Newdale, 6B00-1323, SR403, and M109. Kernel plumpness data were reported from Hamiota (Brandon), Bottineau, and Sidney. Please refer to Table 18 for further information. Disease data from the Cereal Research Centre in Winnipeg are posted in Table 19. These data primarily include ratings for net blotch and scald.
