“…‘Blizzard’ and ‘Bonneville’ are awned hard red winter wheat cultivars, highly adapted to dryland areas, and display excellent milling and baking quality according to North American standards. Blizzard and Bonneville, released in the USA by Idaho AES in 1989 (Sunderman et al 1991 ) and by the USDA-ARS in 1994 (Souza et al 1995 ), respectively, are closely related (Table S1, https://wheatpedigree.net/ ) and have maintained a high level of resistance to both CB and DB since their registration. Rainer is an awnless winter wheat cultivar released by Saatzucht Donau GesmbH & CoKG (Austria) in 2006.…”

Key message Resistance QTL on chromosomes 1AL and 7AL are effective against common and dwarf bunt, QTL on 1BS affects common bunt and QTL on 7DS affects dwarf bunt in bread wheat. Abstract Common bunt, caused by Tilletia caries and T. laevis, and dwarf bunt, caused by T. controversa, negatively affect grain yield and quality of wheat and are particularly destructive in low-input and organic production systems. Two recombinant inbred line (RIL) populations derived by crossing the highly and durably resistant cultivars ‘Blizzard’ and ‘Bonneville’ to the susceptible cultivar ‘Rainer’ were evaluated for their resistance to common and dwarf bunt in artificially inoculated field and greenhouse trials over two growing seasons and genotyped with a 15 K SNP array. Bunt resistance QTL were mapped to chromosomes 1AL, 1BS, 7AL and 7DS. Common bunt resistance was regulated by the major QTL QBt.ifa-1BS and QBt.ifa-1AL together with the moderate effect QTL QBt.ifa-7AL. Dwarf bunt resistance was on the other hand regulated by the QTL QBt.ifa-1AL, QBt.ifa-7AL and QBt.ifa-7DS. Common bunt resistance QTL exhibited pronounced epistatic effects, while epistatic effects were of smaller magnitude for dwarf bunt QTL. Kompetitive Allele-Specific PCR (KASP) markers were developed from SNPs associated with bunt resistance QTL and successfully used for QTL validation in an independent set of RILs. These KASP markers have the potential to support targeted introgression of QTL into elite wheat germplasm and accelerate breeding for enhanced bunt resistance. Durable protection against both common and dwarf bunt can be achieved by combining multiple resistance genes in the same genetic background.

Common bunt caused by Tilletia tritici and T. laevis has re-emerged as a major threat to wheat yield and quality, especially in organic farming. Resistance against its causal agents is present in the wheat gene pool and provides the most economically efficient and sustainable way to combat the disease since seed treatments approved for organic farming are rare and do not always provide full protection. We tested a winter wheat diversity panel with 128 lines for common bunt resistance in Austria and Czechia, and evaluated the applicability of marker-assisted selection (MAS) via Kompetitive Allele-Specific PCR markers in genotypes with high variation in their genetic background. Field trials were conducted across two years and artificially inoculated with local bunt populations. The virulence patterns of these inocula differed between locations and only 15% of the tested genotypes showed stable resistance across test sites. Number and weight of bunt sori relative to the total number and weight of wheat grains in sampled ears revealed that partial infections of ears were frequently appearing. Forty-two breeding lines harboring combinations of four different resistance QTL were developed through MAS. Out of these, a quarter were resistant with a maximum of 5% common bunt incidence. On the other hand, only six out of 46 tested commercial cultivars and breeding lines showed no infection with common bunt, underlining the present scarcity of bunt-resistant cultivars for organic wheat production. By this study we showed that MAS is a useful tool to speed up the selection of resistant lines even in populations with highly diverse genetic backgrounds, and that it is efficient in pyramiding resistance loci and thereby improving the level of resistance.

“…Juniper has an unpigmented coleoptile and a prostrate seedling growth habit. At an average height of 102 cm in 20 trials (Table 1), Juniper does not appear to have genes for semidwarf plant type as it is taller than the full‐stature cultivars Weston (93 cm, p < 0.05) and Bonneville (89 cm, p < 0.01, Souza et al, 1995). Juniper has dark green foliage with slender, recurved, and nontwisted flag leaves.…”

‘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.
