Montana averages 600,000 acres of durum production and ranks second in the US as a durum producer.  Late season rainfall can cause high deoxynivalenol (DON) levels caused by Fusarium head blight (FHB) in harvested grain resulting in it being rejected at the grain elevator. To address FHB concern in Montana grain we have acquired durum lines from our collaborator, Dr. Xiwen Cai, with Fhb1, Fhb5, and non-FHB sources of resistance integrated from hexaploid wheat that we will test for FHB resistance. Additionally, we are working with Dr. Cai to move Fhb7 resistance sources into Montana FHB resistant lines. The introgression of Fhb7 into bread wheat and durum wheat from Thinopyrom ponticum has been shown to greatly reduce disease severity and DON accumulation. We will conduct field-based screening for FHB resistance at the MSU Eastern Agricultural Research Center (EARC, Sidney, MT) which is in the center of the most important region for durum production in Montana. In fact, the northeast region of Montana where EARC is located is on the border of North Dakota and their most important durum production area and thus is the most relevant region for durum FHB resistance screening. The development and release of FHB resistant durum lines will substantially decrease durum yield losses due to FHB and reduce DON levels in MT grown durum.
