Narrative
USDA Fortress is a high yielding, six-rowed, mid-season maturing, winter feed barley adapted to the Southern Plains and the first multiple-aphid resistant barley cultivar in the U.S. USDA Fortress is the result of a repeated, modified backcross between greenbug resistant ‘Post 90’ and Russian wheat aphid resistant source R012. USDA Fortress is highly resistant to both greenbug and RWA. Seedling screening under quarantine in the greenhouse suggests that Fortress is also highly resistant to hedgehog grain aphid, HGA, a newly introduced aphid pest of small grains in the U.S. Over 18 location years, in the absence of aphids, grain yield of USDA Fortress was 23% and 12% greater than Thoroughbred and Post 90, respectively. Thoroughbred had a higher than average test weight (49 lbs/bu) while Post 90 and USDA Fortress had average test weight (48 and 47 lbs/bu, respectively). USDA Fortress has stable grain yield over state-wide variability in climatic conditions including drought.
