The inheritance of durable resistance of selected spring barley varieties to Rhynchosporium secalis was investigated. Data from the F2 generation of a 4 × 4 diallel, without reciprocals and the F4 generation of three crosses selected out of this diallel, suggest that resistance in this sample of varieties tested is complex, in inheritance. Significant additive effects were detected indicating that the; resistance level of barley cultivars may be improved by the hybridisation of suitable varieties. However, the genes conferring resistance seem to be concealed by the expression of one completely dominant resistance gene in our set of varieties. These results are partly in conflict with previous results on the inheritance of resistance to it R . secalis in the breeder's line 1l258/228613A' indicating that the effectiveness of this resistance gene may be greatly influenced by the genetic background of the current population of R . secalis.
