Interpretive Summary: This report represents a compilation of data contributed by participating barley breeders located throughout the growing region. With cooperators in 8 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. Ten 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 six days later than the average. Average yield (6032 kg/ha or 112 bu/a) was well above both the 30-year average and the 4710 kg/ha of last year. Only two stations reported test weight; the average was the lowest in the last 30 years. Average plant height was 93 cm, which is much taller than that of last year and the tallest since 1985.

Technical Abstract: Ten 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 the 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 six days later than the average. The average planting date of April 23rd was six days earlier than last year. Heading date (June 30th) was two days later than last year. Average yield (6032 kg/ha or 112 bu/a) was well above both the 30-year average and the 4710 kg/ha of last year, although it should be noted that the Sidney site was irrigated. Entries with the best yields were BT495, M115, M119, M118, and M112. Only two stations reported test weight; the average of 53 kg/hl was the lowest in the last 30 years. The greatest test weights were recorded for 2ND19119, Conlon, 6B99-6639, Newdale, and 2ND19854. Lodging data were reported from six locations, including Crookston, Fargo, Carrington, Osnabrock, Sidney, and Hamiota. The five entries with the least lodging were ND16301, M116, M119, 6B98-9022, and Drummond. Please note 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. Average plant height was 93 cm, which is much taller than that of last year and the tallest since 1985. Shortest entries were M119, M116, M118, M115, and 2ND19854.
