Summary: Genomics and high throughput phenomics have the potential to revolutionize wheat breeding. This study compared single and multi-trait GS models for predicting GPC and grain yield in wheat, showing that including secondary traits in the models increased accuracy. Spectral information collected at heading was superior for predicting GPC, while grain yield was more accurately predicted during the grain filling stage.

Summary: In this study, the genetics controlling the deviations in grain yield and protein content in common wheat were explored using quantitative trait locus analysis. The results showed that these traits were controlled by multiple genes, including several candidate genes. The study confirmed the usefulness of using indices to mitigate the negative correlation between yield and quality in breeding.

Summary: In the last century, wheat breeding programs have consistently increased yield but at the expense of grain protein concentrations. This study identified four genomic regions associated with increases in grain protein content and/or grain yield, providing potential tools for wheat breeding programs to break the negative correlation between these traits.

Summary: To meet the challenge of feeding nearly 10 billion people by 2050, wheat yield must double by that time. However, in the past 20 years, yield growth has slowed down and even become stagnant in major producing countries. Hybrid wheat has been proposed as a solution to overcome this stagnation, but the extent of wheat hybrid vigor remains limited and poorly understood. Research shows that hybrids have a longer grain filling phase and larger grains, leading to increased yield compared to parental lines.

Summary: This study improved the winter frost tolerance of wheat by introducing a recessive vernalization gene. The results showed that the winter frost tolerant cultivar Lunxuan 103 exhibited strong winter frost tolerance and had better performance in terms of winter-killed seedling/tiller rates, grain yield, and spike number compared to Shimai 12.

Summary: In this study, a diversity panel of wheat accessions was used to analyze and examine the genetic variation in grain copper content. Twelve candidate genes associated with grain copper content were identified through a genome-wide association study, and three of them were considered to be important for wheat grain. Additionally, the study found that grain copper content gradually decreased with release years among wheat accessions in China, and was influenced by yield factors.

Summary: The production and quality of wheat are affected by abiotic constraints such as water stress and soil nutrient deficiencies. Developing drought-tolerant wheat varieties with high yield potential and enhanced grain protein content is crucial for food security. The role of silicon in improving plant nutrition and drought tolerance, as well as the genetic control of silicon uptake for drought adaptation and improved grain yield, are discussed. Limited progress has been made in breeding for drought tolerance in wheat, particularly in sub-Saharan Africa, due to limited understanding of the genetic basis for silicon uptake.

Summary: This study identifies key loci and candidate genes associated with grain size and yield in bread wheat by phenotypic characterization and genetic analysis. The improved variety has larger grain size but lower protein content, which may be attributed to the presence of superior alleles at key loci in the improved variety.

Summary: In the genetic study of durum wheat in Canada, QTL mapping was conducted to identify loci associated with grain protein concentration (GPC). Several major and minor QTL were discovered on different chromosomes, with some being consistently detected across multiple years and showing potential for improving both GPC and grain yield. The results of traditional and conditional mapping provide valuable insights for the development of high GPC and high yielding durum cultivars.

Summary: Analyzing the contribution of nitrogen uptake and utilization in grain yield and protein quality is crucial for improvements in rice-wheat and soybean-wheat cropping systems. Nitrogen uptake efficiency and utilization efficiency have high explanatory power for yield variation, while the contribution of fertile spikes and grain number per spike to grain yield varies in different rotation systems.

Summary: A combining-ability analysis was conducted to select desirable parents and progenies with enhanced response to selection under water-limited environments. Distinctly related drought-tolerant bread wheat genotypes were evaluated for agronomic and physiological traits under well-watered and terminal-drought conditions. The results indicated significant variations in general and specific combining ability for several agronomic and physiological traits, highlighting the potential for breeding high-yielding wheat genotypes for water-limited environments.

Summary: The study sequenced 242 accessions of Aegilops tauschii and identified a rare lineage contributing to the wheat D subgenome. Through association mapping, genomic regions with candidate genes for disease and pest resistance were identified and successfully transferred into wheat. Exploiting the genomic diversity of the wild progenitor allows for rapid trait discovery and functional genetic validation.

Summary: This study investigated the genetic basis of resistance against Fusarium head blight and the mycotoxin deoxynivalenol in Aegilops tauschii, the diploid progenitor of the wheat D subgenome. By analyzing a panel of Ae. tauschii accessions, a uridine diphosphate (UDP)-glucosyltransferase (UGT) gene on chromosome 5D was identified as the causal variant for susceptibility to the mycotoxin. This UGT gene was also found to be involved in DON detoxification in hexaploid wheat. The findings highlight the conservation of this resistance mechanism in wheat and barley.

Summary: This study utilized a historical dataset spanning 11 years in an Austrian winter wheat breeding program to assess genomic and pedigree-based linear and semi-parametric prediction methods for stripe rust resistance. Semi-parametric genomic modeling demonstrated the highest predictive ability and genetic variance, albeit with minimal differences among models. The incorporation of significant QTL as covariates improved predictive ability in certain years, as identified through genome-wide association analysis. Overall, predictive ability was moderate within years but poor in cross-year frameworks.

Summary: The aim of this study was to dissect the genetic architecture of WDV resistance in resistant germplasm and to identify quantitative trait loci (QTL) to support resistance breeding. QTL analysis revealed two highly significant QTL, Qwdv.ifa-6A and Qwdv.ifa-1B, which explained up to 73.9% and 15.8% of the phenotypic variance, respectively. These QTLs are important resources for improving WDV resistance in wheat.

Summary: Fusarium head blight (FHB) is a destructive wheat disease causing yield losses and mycotoxin contamination in crop. Study shows strong correlation between resistance against multiple Fusarium species, mycotoxin contents, FHB severity and FHB-associated traits. Indirect phenotypic and genomic selection, using low anther retention and evaluating pre-selected genotypes in disease nurseries, is suggested as a suitable strategy for breeding wheat cultivars with reduced risk of mycotoxin accumulation.

Summary: Durum wheat lines were analyzed to investigate the genetic basis of Fusarium head blight (FHB) resistance. A broad variation in FHB resistance was observed among the lines, with anthesis date and plant height strongly influencing FHB severities. Seven quantitative trait loci (QTL) affecting FHB severities were identified, including the highly significant Fhb1 QTL from hexaploid wheat.
