“…Epistatic and epistatic × environment interactions are the genetic basis for some traits, as demonstrated in recent QTL mapping studies . In the present study, five pairs of QTLs with an epistatic effect were identified for PV, TV, SB, and PT, accounting for 0.67, 3.35, 2.97, 8.57, and 2.34% of the phenotypic variance, respectively.…”

“…Recently, a large number of QTL studies have been performed to determine the genetic basis of pasting properties in wheat. Researchers have found that QTLs for pasting properties are widely distributed on all 21 wheat chromosomes [1,[16][17][18][19][20][21][22]. Among them, QTLs for PV are mainly located on chromosomes 1A, 1B, 3A, 3B, 3D, 4A, 4B, 6D, 7A, and 7B [1,17,19,20,23], and QTLs for SB are mainly on chromosomes 1A, 3B, 4A, 6D, and 7B [1,19,20,24,25].…”

Protein hydrolysis is widely used in the food industry to improve food or industrial quality, and processing is carried out concurrently or subsequently to starch pasting. In this study, QTL mapping of the pasting properties of natural wheat flour (NWF) and papain‐treated flour (PTF) was performed in three environments. These analyses involved a set of 173 F9:10 recombinant inbred lines (RILs) derived from “Shannong01‐35 × Gaocheng9411” with a genetic linkage map consisting of 6248 molecular markers. The additive, epistatic, and epistatic × environment interaction effects of QTLs for pasting properties were analyzed. A total of 43 and 31 additive QTLs for pasting properties were detected using NWF and PTF, respectively. QPv1A.4‐1, QPv4B.4‐17, QTv1A.4‐1, QTv4B.4‐17, QSb4B.4‐17, QPt1A.4‐1, and QPt4B.4‐17 were identified using both NWF and PTF. In contrast, QPv6A.2‐128, QTv6A.2‐128, QFv6A.2‐75, and QBd6A.2‐128 were only identified in wheat flour; thus, these QTLs are related to the papain digestion site. Five and eight pairs of epistatic interaction QTLs were identified in NWF and PTF, respectively. QPv1A.4‐1/QPv4B.4‐17 and QTv1A.4‐1/QTv4B.4‐17 were identified in NWF and PTF, whereas, QInA1A.4‐1 and QInA4B.4‐17 were only detected in PTF. Two and three pairs of epistatic × environment interactions were detected in NWF and PTF, respectively. In the present study, two important QTL clusters (≥3 QTLs) were detected from NWF, and three clusters were detected from PTF. The results of the comprehensive evaluation of protein hydrolysis and starch pasting provide valuable information to facilitate the improvement of wheat flour quality and promote the molecular breeding of wheat.

“…Although there are many reports on QTL for quality traits in wheat (Huang et al, 2006 ; McCartney et al, 2006 ; Sun et al, 2008 ; Patil et al, 2009 ; Zhao et al, 2009 ; Tsilo et al, 2011 ; Li et al, 2012 ; Deng et al, 2013 , 2015 ; Zheng et al, 2013 ; Prashant et al, 2015 ), few genes are identified in single QTL analysis. The main reason is that SSR markers previously used in QTL analysis have insufficient density and are often in non-coding regions.…”

“…Dough strength and starch pasting characteristics are quantitative traits controlled by multiple genes. Several QTLs for Mixograph (Huang et al, 2006 ; McCartney et al, 2006 ; Patil et al, 2009 ; Tsilo et al, 2011 ; Li et al, 2012 ; Deng et al, 2013 ; Zheng et al, 2013 ; Prashant et al, 2015 ) and RVA parameters (McCartney et al, 2006 ; Sun et al, 2008 ; Zhao et al, 2009 ; Deng et al, 2015 ) were reported using different populations. However, these reports were primarily based on simple sequence repeat (SSR) markers, resulting in relatively large genetic distances defining QTL and markers due to the limited numbers of such markers, which leads to difficulty for gene cloning based on QTL analysis and marker-assisted selection (MAS) in wheat breeding.…”

Dough rheological and starch pasting properties play an important role in determining processing quality in bread wheat (Triticum aestivum L.). In the present study, a recombinant inbred line (RIL) population derived from a Gaocheng 8901/Zhoumai 16 cross grown in three environments was used to identify quantitative trait loci (QTLs) for dough rheological and starch pasting properties evaluated by Mixograph, Rapid Visco-Analyzer (RVA), and Mixolab parameters using the wheat 90 and 660 K single nucleotide polymorphism (SNP) chip assays. A high-density linkage map constructed with 46,961 polymorphic SNP markers from the wheat 90 and 660 K SNP assays spanned a total length of 4121 cM, with an average chromosome length of 196.2 cM and marker density of 0.09 cM/marker; 6596 new SNP markers were anchored to the bread wheat linkage map, with 1046 and 5550 markers from the 90 and 660 K SNP assays, respectively. Composite interval mapping identified 119 additive QTLs on 20 chromosomes except 4D; among them, 15 accounted for more than 10% of the phenotypic variation across two or three environments. Twelve QTLs for Mixograph parameters, 17 for RVA parameters and 55 for Mixolab parameters were new. Eleven QTL clusters were identified. The closely linked SNP markers can be used in marker-assisted wheat breeding in combination with the Kompetitive Allele Specific PCR (KASP) technique for improvement of processing quality in bread wheat.

Starch is the main component of wheat (Triticum aestivum L.) flour, and its quality directly affects the processing quality of the final product. To investigate the genetic basis of starch, this study assessed the starch quality traits of 341 winter wheat varieties/lines grown in Emin and Qitai during the years 2019–2020 and 2020–2021. A genome‐wide association study was conducted with the genotype data obtained from wheat 40K breeding chips using the mixed linear model. Wheat starch quality traits exhibited coefficients of variation ranging from 1.43% to 23.66% and broad‐sense heritabilities between 0.37 and 0.87. All traits followed an approximately normal distribution, except for T. There were highly significant correlations among starch quality traits, with the strongest correlation observed between final viscosity (FV) and trough viscosity (TV) (r = 0.748), followed by peak viscosity and breakdown (BD) (r = 0.679). Thirty‐four single‐nucleotide polymorphism markers significantly and stably associated with starch quality traits were identified, clustering in 31 genetic loci. These included one locus for TV, six loci for BD, three loci for FV, two loci for peak time (PT), 12 loci for T, five loci for falling number, and two loci for damaged starch. One PT‐related block of 410 kb was identified in the region of 596 Mb on chromosome 5A, where significant phenotypic differences were observed between different haplotypes. One Kompetitive allele‐specific PCR (KASP) marker for T was developed on chromosome 7B, and two KASP markers for BD were developed on chromosome 7A. Four candidate genes possibly affecting BD during grain development were identified on chromosome 7A, including TraesCS7A02G225100.1, TraesCS7A02G225900.1, TraesCS7A02G226400.1, and TraesCS7A02G257100.1. The results have significant implications for utilizing marker‐assisted selection in breeding to improve wheat starch quality.
