The newer advanced 2-row lines WA8608-97, WA8601-97, WA10144-96, and WA8792-
96 have performed particularly well in agronomic terms (Table 4), and WA10144-96
appears to have good export malting quality, while the other lines appear to have little
malting quality potential (Table 5). WA8674-96 and WA7908-96 were entered into the
2001 AMBA Pilot Scale Testing Program (Table 6), but were put on hold in the program
because of overall performance until the pilot malt results are known. A major objective
in the 2-row program, as well as the 6-row program, which has been met with
considerable success, is to increase kernel size (% plump). This is particularly
advantageous in dry years, as most of Washington barley production is dryland. Another
objective is to reduce plant height and increase lodging resistance to effectively extend
adaptation to irrigated production. Incorporating barley stripe rust resistance into
breeding lines is a major objective as well.
