Interpretive Summary: Viral diseases in wheat can cause significant losses in production. They often are difficult to control, no chemical treatments can directly impede their progress. Some viruses are introduced to plants by insect vectors. In such cases, control of the insect can indirectly limit the spread of the virus. Deployment of natural resistance genes is the most effective means of control. Wheat soilborne mosaic virus (WSBMV) impacts wheat production in the eastern portion of the Wheat Belt. It is especially common in low lying spots in fields, especially in damp springs. WSBMV is introduced to the wheat plant by swimming spores of Polymyxa graminis, a root-infecting fungus. To limit yield losses due to WSBMV infection, USDA-ARS cooperated with the University of Nebraska to develop NE01481, a hard red winter wheat carrying natural resistance to viral infections. NE01481 was released because of its superior grain yield in rainfed wheat production systems in southeastern, south central, and southwestern NE.
Technical Abstract: 'NE01481' (Reg. No. PI 659689) hard red winter wheat (Triticum aestivum L.) was developed cooperatively by the Nebraska Agricultural Experiment Station and the USDA-ARS and released in April, 2010. Nebraska wheat growers, in addition to superior agronomic performance, would like to have increased resistance to wheat soilborne mosaic virus. NE01481 was selected from the cross NE92458/Ike that was made in 1995. The pedigree of NE92458 is OK83201/’Redland’ and the pedigree of OK83201, an experimental line developed by Oklahoma State University is ‘Vona’ //’Chisholm’/’Plainsman V’. NE01481 was selected using the bulk breeding method as an F3:4 line (F3-derived line in the F4 generation) in 1999, and in 2001 was assigned experimental line number NE01481. NE01481 was released because of its superior grain yield in rainfed wheat production systems in southeastern, south central, and south western NE and that it is first modern release from our program that is resistant to wheat soilborne mosaic virus.
