The linkage group of the gene for greenbug ( Schizaphis graminum Rondani) resistance in the barley ( Hordeum vulgare L.) cultivar ‘Will’ was determined by using primary trisomics and tertiary trisomic homozygous translocations. The gene for greenbug resistance was found to be on linkage group 1 and on the centromere‐bearing segment of chromosome 1 in the Tl‐6a translocation. Previous attempts to locate the gene using standard marker genes were unsuccessful.
