Abstract

Fusarium head blight (FHB) [caused by Fusarium graminearum Schwabe; telomorph Gibberella zeae (Schwein.) Petch] is a major disease of winter wheat (Triticum aestivum L.) in the US mid-Atlantic region. The objective of this research was to derive soft red winter wheat (SRWW) germplasm with enhanced FHB resistance for this region. MD01W233–06–1 (Reg. No. GP-857, PI No. 658682) is a soft red winter wheat (SRWW) (Triticum aestivum L.) germplasm line developed at the University of Maryland and released by the Maryland Agricultural Experiment Station in 2009. MD01W233–06–1 was selected from the cross ‘McCormick’/‘Choptank’ made in 2001. McCormick and Choptank are SRWW cultivars adapted to the US mid-Atlantic region. MD01W233–06–1 was selected as an F3:5 line selection in Queenstown, MD in June 2006. MD01W233–06–1 has type II resistance to FHB that is different from that of ‘Sumai 3’. Additionally, it has resistance to the Ug99 race of stem rust. These characteristics make this line a valuable contribution for breeding for enhanced FHB resistance in the US mid-Atlantic.
