Varieties used for comparison: 'Xena' and 'McLeod'
Summary: The pubescence on the blade and auricle margins of flag leaf of 'Champion' is sparser than 'Xena'. 'Champion' has weaker anthocyanin colouration of the auricles than 'Xena' and 'McLeod'. The spike attitude of 'Champion' is more erect than 'Xena'. 'Champion' has a tapering spike shape while it is parallel shaped in 'Xena' and 'McLeod'. The spike density of 'Champion' is greater than 'McLeod'. 'Champion' has the glume and awn equal in length relative to the grain of the median spikelet , while it is longer in 'Xena' and shorter in 'McLeod'. The plant height of 'Champion' is taller than 'McLeod'. 'Champion' has longer rachilla hair on the kernel than 'McLeod'. The kernel of 'Champion' has stronger spiculation of the inner lateral nerves of the dorsal side of the lemma than 'Xena' and 'McLeod'. 'Champion' has more hair on the ventral furrow of the kernel than 'Xena'. The disposition of the lodicles of the kernel of 'Champion' is clasping while it is more frontal in 'McLeod'.

AGRONOMY: fair to good resistance to lodging and shattering, fair to good tolerance to straw breaking, neck breaking and drought
Origin & Breeding History: 'Champion' was developed by WestBred LLC, Bozeman, Montana from a cross made in 1997 between Baroness / Camas. The F1 seed was planted near Yuma, Arizona in 1997, with the F2 seed harvested in April 1998. The F2 seed was planted near Bozeman, Montana in September 1998 where spikes were selected from the F2 plants and used to plant single F3 rows near Bozeman in May 1999. Single spikes were selected from the F3 rows in September 1999 and planted as single rows near Bozeman, Montana in May 2000. Single spikes were selected from the F4 rows in October 2000 and planted as single F5 rows in Yuma, Arizona in November 2000. Agronomically desired rows were selected, harvested and given permanent numbers. One such row was given the experimental designation YU501-385. The F6 seed from this row was used to plant plots near Bozeman, Montana and near Calgary, Alberta. Seed from the Bozeman plot was harvested in September 2001 and used to plant replicated yield trials near Bozeman, Montana and three locations in Alberta in May 2002. Continued yield testing of the F8-11 generations was performed in 2003-2006 in the states of Washington, Idaho, Montana and the provinces of Alberta, Saskatchewan and Manitoba.
'Champion' was entered into the Canadian Western 2-row Barley Coop trial in the spring of 2004 and 2005 under the designation 'TR04-719'. 'Champion' was also tested simultaneously throughout the Pacific Northwest in the state extension trials and the Western Regional Spring Barley Nursery in 2004 and 2005.
Tests & Trials: Tests and trials were conducted during the summers of 2006 and 2007 in Neapolis, Alberta. Plots consisted of 5 rows per variety, with a row spacing 23 of centimetres and a row length of 5 meters. There were 3 replicates arranged in an RCB design.
