“…The objective of this study was to identify QTL and molecular markers associated with the dwarf bunt resistance in ‘Idaho 444′ (IDO444, PI 578278, Windes et al 1995). IDO444 demonstrated high levels of resistance to dwarf bunt during its years of testing, but was not released as a cultivar due to its inferior milling and baking quality.…”

Key message A novel QTL, Q.DB.ui-7DS, and the PCR-based markers identified in the current study will accelerate variety development for resistance to dwarf and common bunt of wheat. AbstractDwarf bunt [Tilletia controversa J.G. Kühn [as ‘contraversa’], in Rabenhorst, Hedwigia 13: 188 (1874)] is a destructive disease of wheat (Triticum aestivum L.) that reduces grain yield and quality. A number of distinct genes conferring resistance to dwarf bunt have been used by breeding programs for nearly 100 years. However, few markers were identified that can be used in selection of dwarf bunt resistance. A recombinant inbred line (RIL) population derived from the bunt-resistant germplasm, Idaho 444 (IDO444), and the susceptible cultivar, Rio Blanco, was evaluated for phenotypic reaction to dwarf bunt inoculation in four trials in two locations (USU and USDA) over 3 years. The population was genotyped with the Diversity Arrays Technology (DArT) and the Illumina Infinium 9K iSelect marker platforms. A total of three QTL were detected, and resistant alleles were from IDO444. QTL Q.DB.ui-7DS on 7DS was determined based on the location of a DArT marker wPt-2565 (X116197), which was consistently detected and explained 32 to 56 % of phenotypic variation among the four trials. QTL Q.DB.ui-1A on 1A was detected in three Utah State University (USU) trials and explained 11–15 % of phenotypic variation. QTL Q.DB.ui-2B on 2B was detected in two USU and one United States Department of Agriculture (USDA) trials and explained up to 6 % of phenotypic variation. Two PCR-based markers were developed based on the sequence of wPt-2565 and validated in the RIL population and used in genotyping of dwarf bunt differential lines, known resistance sources, and resistant cultivars.

“…Juniper derives from a cross, designated A91013W, with the pedigree IDO352/UT165093. IDO352 is a tall hard red winter wheat breeding line with a complex pedigree and breeding history, which is described in Windes et al (1995) IDO352 was developed at the University of Idaho and carries novel resistance to dwarf bunt, which is caused by Tilletia controversa Kühn in Rabenh. UT165093 is a hard red winter wheat breeding line from Utah State University with the pedigree ID51022/‘Manning’.…”

‘Juniper’ (Reg. No. CV‐1021, PI 639951) is a hard red winter wheat (Triticum aestivum L.) developed by the Idaho Agricultural Experiment Station and released in February 2006. Juniper was tested under the experimental numbers A91013W‐1 and IDO575. It is a full‐stature wheat released for very low rainfall, crop‐fallow rotations of the Intermountain West and was released for its improved resistance to stripe rust (Puccinia striiformis Westend) and dwarf bunt (Tilletia controversa Kühn in Rabenh) and bread‐baking quality compared with current full‐stature cultivars. Juniper had an average yield in rainfed trials of 3290 kg ha−1, compared with the other tall cultivars for this region, ‘Weston’ and ‘Bonneville’, which had grain yields of 3050 and 3180 kg ha−1, respectively. Weston has undesirable baking quality due to short dough mixing time. Juniper has nearly a full minute longer mixograph mixing time compared with Weston (p < 0.01). Juniper also has similar snow mold tolerance (causal organism Typhula spp.) to Bonneville without the undesirable characteristic of late heading date and maturity. Juniper heads 3 d earlier than Bonneville.
