Technical Abstract: A spring wheat variety named BacUp was released jointly by the USDA-ARS and Minnesota Agricultural Experiment Station in February 1996. Due to the devastation caused by head scab (Fusarium graminearum Schawbe), losses estimated to exceed $1 billion dollars in the 1990's, resistant varieties are desperately needed. The cross that resulted in BacUp was made by the Pioneer spring wheat program, which was discontinued in 1989. Continuous screening of early generation germplasm resulted in this selection, which has both resistance to spread of disease in the head and ability to hold test weight and kernel weight in severe epidemics. Its pedigree is Nuy Bay/2375//Marshall, with Nuy Bay providing the very high resistance to spread in the spike, 2375 providing the ability to retain kernel and test weight, and Marshall providing adaptability. Because of critical need for resistance, BacUp was not as extensively yield dtested and purification of the seed source for off-types was not done before release. BacUp is characterized by very high grain volume weight and grain protein content, resistance to leaf and stem rust, and early maturity. Milling and baking characteristic are acceptable. A maximum of 15 to 20% of a producer's acreage is suggested because BacUp has low yield potential and lodging susceptibility.
