Sources of resistance to Fusarium head blight within Syrian durum wheat landraces

摘要

P>Fusarium head blight (FHB) is a destructive disease of wheat all over the world. FHB causes high economic losses for durum wheat because of the lack of resistance sources. Initially, sixty-eight Syrian landraces were tested in field conditions after inoculation to discriminate the most resistant and environmentally stable landraces. Further tests across a total of four environments revealed four landraces with a low mean FHB rating (19-25%) compared to common German durum varieties (56-60%) and an environmentally stable resistance. They are considered as promising resistance sources to FHB for introgression in the adapted durum wheat gene pool.
