“…The MPT values in this line were 23.7% higher than the lowest values observed in Chu_A3 (Table 5). The good performance of Glu-A3f allele has been observed also by Tsenov et al (2010), who reported a strong positive effect of this allele on end-use quality.…”

a b s t r a c tLow molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their complex protein banding patterns in SDS-PAGE and tight linkage with gliadins at the Gli-1 locus. Using DNA markers and a backcross program, we developed a set of nine near isogenic lines (NILs) including different Glu-A3/Gli-A1 or Glu-B3/Gli-B1 alleles in the genetic background of the Argentine variety ProINTA Imperial. The nine NILs and the control were evaluated in three different field trials in Argentina. Significant genotype-by-environment interactions were detected for most quality parameters indicating that the effects of the Glu-3/Gli-1 alleles are modulated by environmental differences. None of the NILs showed differences in total flour protein content, but relative changes in the abundance of particular classes of proteins cannot be ruled out. On average, the Glu-A3f, Glu-B3b, Glu-B3g and GluB3i Man alleles were associated with the highest values in gluten strength-related parameters, while GluA3e, Glu-B3a and Glu-B3i Chu were consistently associated with weak gluten and low quality values. The value of different Glu-3/Gli-1 allele combinations to improve breadmaking quality is discussed.

“…However, this allele was absent in HWCs and present in only three (2.8%) WLRs (from northern and high‐altitude parts of Pakistan). Tsenov et al (2010) reported that the contribution of Glu‐A3 was the highest among the LMW‐GS loci, especially Glu‐A3f , which has a strong positive effect on end‐use quality against the backgrounds of all HMW‐GS combinations. Alleles at Glu‐B3 were ranked Glu‐B3b = Glu‐B3d = Glu‐B3 g > Glu‐B3h > Glu‐B3a > Glu‐B3c for dough strength (Cornish, 2007), whereas ranking for dough extensibility was Glu‐B3i > Glu‐B3f = Glu‐B3 g > Glu‐B3h > Glu‐B3a ≥ Glu‐B3b > Glu‐B3d (Zhang et al, 2012b).…”

We investigated alleles at 31 loci associated with adaptability, yield, and end‐use quality in 107 wheat (Triticum aestivum L.) landraces (WLRs) and 121 improved historical wheat cultivars (HWCs) from Pakistan. The WLRs were categorized into two further subgroups: 36 pre‐Green‐Revolution landraces released as cultivars and 71 geographically spread landraces from all over Pakistan. Alleles Vrn‐A1a, TaGW2‐6A‐A, TaCKX6‐D1b, Pinb‐D1b, Psy‐A1b, and Wx‐D1b were absent in WLRs, whereas ample diversity was observed at all other loci. In HWCs, only Wx‐D1b and Glu‐A3e were absent among the alleles tested, whereas the alleles Ppd‐D1a (90%), Rht‐B1b or Rht‐D1b (83.4%), TaCwi‐A1a (95%), TaGW2‐6A‐G (76%), TaCKX6‐D1a (77.3%), Glu‐A1b (66.1%), Glu‐D1d (61.3%), Pina‐D1b (88.2%), Pinb‐D1a (90%), Psy‐A1a (66.1%), Psy‐B1b (81.8%), Psy‐D1a (86.5%), Ppo‐A1a (70%), TaZds‐D1b (73.9%), TaLox‐B1b (80.1%), and Wx‐D1a (100%) predominated, indicating significant improvement in adaptability, yield potential, and end‐use quality and unconscious selection for favored alleles. Higher frequencies of favored alleles at the TaCwi‐A1 and TaCKX6‐D1 loci influencing 1000‐kernel weight (TKW) in HWCs indicated that selection pressure on these alleles during breeding successfully contributed to cultivar improvement. Wright's pairwise fixation index (Fst) statistics indicated greater genetic divergence between HWC and WLR collections (0.16) than HWC and WLR cultivars (0.14). Population structure based on functional markers (FMs) using principal component analysis partitioned the germplasm into two distinct groups. High genetic divergence and low admixture between HWCs and WLRs indicated limited use of landraces in wheat breeding in Pakistan. Our results suggested these collections as rich reservoirs of alleles and haplotype combinations that may be useful in future breeding programs.

“…An extensive survey of LMW-GS compositions in 222 hexaploid wheat cultivars using SDS-PAGE revealed a total of 20 protein alleles, with six (a, b, c, d, e, f), nine (a, b, c, d, e, f, g, h, and i), and five (a, b, c, d, and e) being identified at the Glu-A3, Glu-B3, and Glu-D3 loci, respectively (Jackson et al 1996). Previous reports have shown that allelic variations of LMW-GS at the Glu-3 locus had a significant influence on dough extensibility of wheat flours, accounting for up to 75% of the total gluten (Gupta et al 1994;Tsenov et al 2010;Wang et al 2016).…”

Landraces and historical varieties are necessary germplasms for genetic improvement of modern cereals. Allelic variations at the Glu-1 and Glu-3 loci in 300 common wheat landraces and 43 historical varieties from Xinjiang, China, were evaluated by Sodium-dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and allele-specific molecular markers. Among the materials investigated, three, nine, and seven alleles were identified from the Glu-A1, Glu-B1, and Glu-D1 loci, respectively, and a total of 26 high-molecular-weight glutenin subunit (HMW-GS) combinations were found, of which 18 combinations were identified in landraces and historical varieties. Allelic frequency of HMW-GS combinations null, 7 ? 8, 2 ? 12 was found to be the highest in both the landraces (63.3%) and historical varieties (39.5%). Besides, some distinctive HMW-GS alleles, such as the novel Glu-B1 allele 6.1* ? 8.1* and Glu-D1 alleles 2.6 ? 12, 2.1 ? 10.1, and 5** ? 10 were observed in Xinjiang wheat landraces. Among the Glu-A3 and Glu-B3 loci of landraces and historical varieties, a total of eight and nine alleles were found, respectively. At each locus, two novel alleles were identified. A total of 33 low-molecularweight glutenin subunit (LMW-GS) combinations of Glu-A3 and Glu-B3 were identified, with 31 and 14 combinations occurring in landraces and historical varieties, respectively, but only 10 combinations shared by both of them. As Glu-D1, Glu-A3, and Glu-B3 have highest contribution to the end-use quality and processing properties as compared to Glu-A1, Glu-B1, and Glu-D3 locus, the novel or distinctive HMW-GS and LMW-GS alleles in these loci could potentially be utilized for the improvement in the quality of modern wheat.
