Annual Progress Report on Malting Barley Research March, 2007

Lines M122 and M124 were rated satisfactory in their first year of AMBA pilot-scale malt
evaluations. M122 is superior to Robust in yield and agronomically competitive with other
current varieties. M122 not as resistant to lodging as many of the current varieties and
similar to Robust in both height and lodging. M122 continues to demonstrate resistance to
FHB with about 40% of the disease severity and 50% the level of DON. This level of
resistance has been consistently observed in trials over the last four years. Grain samples
from 2006 trials have been sent to the CCRU Malt Quality Lab at Madison, however no
data is available yet. Please refer to last years report for quality data from 2005.

M124 is superior to Lacey in yield, but similar to Robust in lodging (Table 5). It is also
similar to Lacey in response to the current diseases in the region including FHB. This is the
last line that we have advanced to AMBA pilot malt evaluation from our breeding program
that does not have enhanced disease resistance over the currently available varieties.
2006 crop year quality data is not yet available. From previous years data, M115 is higher
in malt extract and lower in grain protein compared to Robust. Both M122 and M124 were
submitted for 2 nd year evaluation in AMBA pilot-scale malt evaluation with the 2006 crop.
