Summary

This paper represents a part of the continuing breeding program for resistance to true loose smut in barley in Bulgaria. It is also a continuation of the paper presented on the 8th European Symposium on organic farming in Kassel 2005. Research on seed-borne diseases started in Bulgaria on barley in the 1960´s at the Institute for barley Re-search in Karnobat. Breeding research especially for a later use in organic farming in Bulgaria started 1998 with the present international project managed by Dr. Todorova. 56 dihaploid lines were derived from F1-hybrids of two barley crosses between resis-tant and susceptible Bulgarian and foreign cultivars bearing the resistant genes Run12 and Run13. The DH progenies were tested in 5 generations for loose smut resistance on the field and in the lab with the embryotest. 10 resistant DH-progenies with gene Run12 and 16 resistant DH-progenies with Run13 were selected. In the last years agronomically characterisation of the future cultivars is going on. 7 dihaploid lines with appropriate agronomic traits are selected for future cultivar developing with true loose smut resistance for organic farming.
