Summary: This study identified genetic loci controlling bread-making quality traits in wheat, with 25 quantitative trait loci associated with these traits on 14 chromosomes. The study also found correlations between certain traits and the presence of known alleles related to the high-molecular-weight glutenin gene Glu-D1. Utilizing QTL analysis and marker screening results can help enrich wheat breeding germplasm with favorable alleles for improved flour quality traits.

Summary: This study aimed to map quantitative trait loci (QTL) responsible for the expression of FHB resistance in two adapted cultivars and evaluate their co-localization with agronomic traits. It was found that FHB resistance QTL co-localized with QTL for plant height, days to heading, and days to maturity. Selecting for improved FHB resistance within adapted cultivars can be done by using markers associated with complementary QTL.

Summary: The present research aims to identify the efficient combination of drought-tolerance selection criteria and associated quantitative trait loci. The results showed that grain number, biomass, number of fertile spikes per plant and ground cover exhibited significant correlation with grain yield, and can be potential secondary selection criteria for yield under drought conditions. Certain markers were associated with yield increase, biomass increase, and improved drought tolerance performance.

Summary: This study assessed the suitability of soft red winter wheat breeding lines for local artisan bakers interested in strong gluten wheat for bread. The heritability of bread quality traits, including loaf volume and dough extensibility, was measured to estimate their genetic characteristics. The flavor and texture heritability estimates ranged from 0.16 to .037.

Summary: This study evaluated the phenotypes of kernel traits and constructed a high-density genetic linkage map to identify related QTLs in a wheat RIL population. A total of 48 QTLs were identified, and the TaTKW-1A gene was found to be closely related to thousand-kernel weight. This study provides a basis for cloning functional genes underlying kernel traits and a reliable marker for molecular breeding.

Summary: The continuous increase in global population drives the need for increased wheat production. Future wheat breeding will heavily rely on dissecting molecular and genetic bases, which is possible through the discovery of QTLs in constructed populations. The evaluation of 92 RILs in this study aimed to search for novel and stable QTLs in wheat.

Summary: There is evidence that the agronomic protocols commonly used in organic and conventional crop production differ significantly and that modern varieties developed for conventional farming systems may not perform optimally in organic farming systems. For organic farming, breeding programs need to focus on traits prioritized by organic farmers, processing quality parameters, and nutritional quality parameters demanded by organic consumers. This article reviews evidence from variety trials and field experiments to explore the need for organic farming focused breeding programs and to determine which traits should be targeted in these programs.

Summary: This study characterized the genetic variability of wheat root architecture by measuring the root and shoot traits of durum and bread wheat varieties. Significant correlations were found between root traits and field agronomic performances, suggesting that investing more resources in roots improved water and nutrient uptake and wheat yield. Genetic analysis identified quantitative trait loci (QTLs) for root traits, some of which colocalized with QTLs for field traits in certain environments. Breeding efforts have resulted in deeper rooting and fewer seminal roots in bread wheat, while the number of tillers has increased in bread wheat but decreased in durum wheat. Breeding for root traits could help maintain current yield and adapt to specific drought scenarios.

Summary: The study investigates the impact of tea polyphenols (TPL) on the gluten network structure in TPL-fortified bread and dough systems. The addition of TPL in bread leads to a deterioration in quality, measurable as reduced loaf volume, increased hardness, and altered sensory properties. In the gluten dough system, TPL decreases the stability and development time of the dough, resulting in a weaker dough with increased elastic modulus. The addition of TPL also affects the protein structure and water distribution in the dough system.

Summary: This study analyzed the genetic basis of adult plant resistance to stem rust in spring wheat line 'Copio'. The results showed that Copio carries multiple resistance genes that provide both race-specific and non-race-specific resistance to diverse races of stem rust fungus. These genes can be used in breeding programs to develop durable resistance in wheat.

Summary: Genetic manipulation of whole-plant transpiration rate in response to atmospheric vapor pressure deficit is a promising approach for crop adaptation to different drought environments. This study identified the genetic basis of transpiration rate response to vapor pressure deficit in wheat and found potential genetic markers on chromosome 5A.

Summary: This study investigated the FODMAP and ATI contents of 22 different wheat varieties and the effect of type I sourdough fermentation on these levels. The results showed that both variety and growing location significantly influenced the levels of FODMAPs and ATIs. Longer sourdough fermentation time resulted in reductions in fructans, raffinose, and ATIs, but a substantial increase in mannitol was observed.

Summary: This study demonstrates that wheat with the Fhb1 quantitative trait locus (QTL) provides reliable resistance to Fusarium head blight (FHB) at elevated CO2 levels. However, the presence of the Fhb1 QTL in more FHB-resistant wheat leads to increased disease spread and mycotoxin contamination.
