Abstract

Leaf stripe, caused by Pyrenophora graminea, is a serious disease of barley in many productionareas. Genetic mapping of major genes and quantitative trait loci for this disease has revealedresistance loci on the chromosomes 1(7H), 2 (2H) and 3(3H). QTLs for partial resistance have beenidentified in segregating populations derived from the crosses between Proctor and Nudinka, L94and Vada, L94 and C123, Steptoe and Morex. Major genes conferring useful range of activity havebeen identified in the barley cultivars Vada and Thibaut. The Thibaut resistance gene, named asRdg2a, has been subjected to high resolution mapping and a syntenic relationship of the resistancegene locus with rice chromosome 6 has been established. In the course of the mapping of major andquantitative disease resistance loci, molecular markers for resistance breeding for disease controlusing gene technology have been identified and validated for utilization in marker assisted selectionof disease resistance.
