Abstract
In order to localize a gene for resistance to Barley Yellow Mosaic Virus (BaYMV) of German resistant varieties, cvs. ‘Ogra’ and ‘Sonate’ were crossed to a complete trisomic (2n=2x+1=15) set of ‘Shin Ebisu 16’. Tests for resistance in F2 strongly support the conclusion that the German gene for resistance to BaYMV is located on barley chromosome 3.
