Stagonospora nodorum Blotch (SNB), caused by Stagonospora nodorum, infests North Carolina wheat fields annually. Severe epidemics of SNB can result in substantial reductions in grain yield, test weight and end-use quality. Resistance to SNB is quantitatively inherited and phenotyping is labor intensive. The North Carolina cultivar NC-Neuse has consistently exhibited moderate levels of resistance to SNB and the cultivar AGS 2000 has consistently exhibited susceptibility to SNB. A recombinant inbred population consisting of 177 F5:6 lines from the cross of NC-Neuse x AGS 2000 was genotyped using DArT and SSR markers, and phenotyped at six field locations in the 2010-2011 field season for SNB reaction and other agronomic traits. An update of pertinent results will be presented.
