ABSTRACT

‘Faller’ (Reg. No. CV-1026, PI 648350) hard red spring wheat (HRSW) (Triticum aestivum L.) was developed at North Dakota State University (NDSU) and released by the North Dakota Agricultural Experiment Station (NDAES). Faller was derived from the ND2857/ND2814 cross made at NDSU in fall 1997. ND2857 (ND2709/ND688) is a hard red spring experimental line with good resistance to Fusarium head blight (FHB) (caused by Fusarium graminearum Schwabe [telomorph Gibberella zeae (Schwein.) Petch]) originating from ND2709, a line known to possess the Fhb1 quantitative trait locus derived from ‘Sumai3’ (PI 481542). Sumai3, a spring wheat from China, is arguably the most widely used source of resistance to FHB in the world. Both ND2709 and ND688 are HRSW experimental lines developed by the NDSU breeding program. ND2814 (‘Kitt’ [PI 518818]/‘Amidon’ [PI 527682]/3/‘Grandin’ [PI 531005]/‘Stoa S’ [PI 520297]) is an HRSW line developed by the NDSU HRSW breeding program. Kitt is an HRSW cultivar released in 1975 by the Minnesota Agricultural Experiment Station and the USDA-ARS, while Amidon, Grandin, and Stoa are HRSW cultivars released by NDAES in 1988, 1989, 1984, respectively. Faller was produced from a bulk of one purified F_4:5 plot selected in 2001 at Christchurch, New Zealand. Faller was released because it combines very high yield with good end-use quality and resistance to FHB and leaf diseases.
