We are in a rebuilding phase for 6-row types. Much of our material was discarded
after the 1998 season due to barley stripe rust susceptibility. Virtually all the 6-row
malting cultivars from the Midwest and West are very susceptible to barley stripe rust,
and of course these cultivars have been used heavily in crossing. Therefore, we are
trying to rebuild with rust resistance as well as quality. Still the most challenging aspect
of our 6-row program is to combine Midwestern quality with western adaptation into
selections acceptable to growers, maltsters, and brewers. And now adding stripe rust
resistance is a further challenge. Simple and complex cross combinations are made to
build the desired new and rare genotypes. There are also several 6-rows and 2-rows in a
stripe rust resistance backcross program.
