Key message: Two mapping approaches were use to identify and validate milling and baking quality QTL in soft wheat. Two LG were consistently found important for multiple traits and we recommend the use marker-assisted selection on specific markers reported here. Abstract: Wheat-derived food products require a range of characteristics. Identification and understanding of the genetic components controlling end-use quality of wheat is important for crop improvement. We assessed the underlying genetics controlling specific milling and baking quality parameters of soft wheat including flour yield, softness equivalent, flour protein, sucrose, sodium carbonate, water absorption and lactic acid, solvent retention capacities in a diversity panel and five bi-parental mapping populations. The populations were genotyped with SSR and DArT markers, with markers specific for the 1BL.1RS translocation and sucrose synthase gene. Association analysis and composite interval mapping were performed to identify quantitative trait loci (QTL). High heritability was observed for each of the traits evaluated, trait correlations were consistent over populations, and transgressive segregants were common in all bi-parental populations. A total of 26 regions were identified as potential QTL in the diversity panel and 74 QTL were identified across all five bi-parental mapping populations. Collinearity of QTL from chromosomes 1B and 2B was observed across mapping populations and was consistent with results from the association analysis in the diversity panel. Multiple regression analysis showed the importance of the two 1B and 2B regions and marker-assisted selection for the favorable alleles at these regions should improve quality. © 2015, Springer-Verlag Berlin Heidelberg.

The objective of this research was to develop widely adapted hard winter wheat (Triticum aestivum L.) varieties to meet the needs of mills, bakeries, and consumers in the eastern and Great Plains regions of the United States. ‘LCS Wizard’ (Reg. No. CV-1111, PI 669574), a hard red winter (HRW) wheat, was developed and tested as VA08HRW-80 and co-released by the Virginia Agricultural Experiment Station and Limagrain Cereal Seeds, LLC in 2013. LCS Wizard was derived from the three-way cross S.6742/92PAN1#33//92PIN#107 using a modified bulk breeding method. LCS Wizard is a widely adapted, high-yielding, awned, semidwarf (Rht1) HRW wheat with midseason spike emergence and resistance or moderate resistance to diseases prevalent in the mid-Atlantic and Great Plains regions. In the 2014 Uniform Bread Wheat Trial conducted over 17 locations in eastern states, LCS Wizard produced an average grain yield of 4717 kg ha−1, similar to ‘Vision 45’ (4650 kg ha−1). In the northern Great Plains, the average grain yield over 54 locations in 2012 of LCS Wizard (4419 kg ha−1) was slightly lower than that of ‘Overland’ (4659 kg ha−1). In the southern Great Plains, its average grain yield (3844 kg ha−1) over 85 locations was slightly higher than that of Fuller (3757 kg ha−1). LCS Wizard has acceptable end-use quality in both the eastern and Great Plains regions of the United States. © 2015 Crop Science Society of America. All rights reserved. Source

‘Vision 45’ (Reg. No. CV-1110, PI 667642), is a hard red winter (HRW) wheat (Triticum aestivum L.) cultivar that was developed and tested as VA07HRW-45 and released by the Virginia Agricultural Experiment Station in 2012. Vision 45 was derived from the cross ‘Provinciale’/‘Vision 10’ using a modified bulk breeding method. It was tested in replicated yield trials in Virginia (2008–2014) and in the USDA-ARS Uniform Bread Wheat (UBW) Trials (2009–2014). Vision 45 is a widely adapted, high-yielding, awned, semidwarf (unknown Rht gene) HRW wheat with mid- to late-season spike emergence, strong straw strength, and resistance or moderate resistance to diseases prevalent in the mid-Atlanticregion. In Virginia, Vision 45 was the highest-yielding hard winter wheat over a 4-yr period, having an average grain yield (5499 kg ha-1) that was slightly higher than the soft red winter wheat cultivar Tribute (PI 654422), which was 5181 kg ha-1. Over 6 yr and 97 environments in the UBW Trials, Vision 45 had an average grain y eld of 4924 kg ha-1, one ofthe highest-yielding hard wheat cultivars. Vision 45 has good end-use quality on the basis of comparisons with the HRW wheat check cultivar Jagger (PI 593688), for flour yield (70.7 versus 70.3 g 100 g-1), flour protein (10.5 versus 10.6 g 100 g−1), flour water absorption (60.7 vs. 61.3 g 100 g−1), dough mixing tolerance (2.7 versus 2.7), pup-loaf volume (798 versus 773 cm3), and crumb grain scores (3.3 versus 2.8). © Crop Science Society of America.

The soft-grained progeny of a recombinant inbred line (RIL) population was characterized for a comprehensive set of quality traits and associated quantitative trait loci (QTLs). The population was derived from the cross Tubbs (soft grained) × NSA 98-0995 (hard grained) and was grown in two crop years in Corvallis, Oregon. Transgressive segregation was observed for all of the studied traits. Hardness index was significantly correlated with several important traits related to the absorption capacity of the flour for diagnostic aqueous solvents. Five lines with a desired combination of superior soft wheat quality traits were also identified. Fifteen QTLs were detected on nine wheat chromosomes for eight traits. The observed transgressive segregation was useful, because RILs with potentially above average soft wheat quality were unexpectedly identified in this hard × soft cross. The QTLs identified in this study could be useful in marker-assisted selection for future preselection of progeny from Tubbs, NSA, or closely related genotypes. © 2014 AACC International, Inc.
