Summary: Wheat leaf rust is a significant fungal disease of wheat, and its control measures often break down when the virulence pattern of the fungus changes. In contrast, einkorn wheat shows prehaustorial resistance, which is not dependent on the specific race of the pathogen. By analyzing the genetic population of einkorn wheat, a major QTL associated with resistance was identified, and a specific gene involved in a hypersensitive defense reaction was found within this QTL interval.

Summary: In this study, four Chinese wheat cultivars were crossed with PI 660,060, a wheat line carrying the Yr62 gene for high-temperature adult-plant resistance to wheat stripe rust. After several generations of breeding, nine wheat lines with good agronomic traits and disease resistance were successfully selected. These selected lines provide material support for future breeding of wheat for stripe rust resistance.

Summary: This study investigated the resistance of 168 pre-breeding lines to local races of leaf rust and yellow rust. Through genome-wide association study, 190 marker-trait associations were identified, with 120 specific to leaf rust and 70 specific to yellow rust. Possible candidate genes at these loci were discussed. Some wheat genotypes carrying multiple resistance loci are suitable for rust resistance breeding programs.

Summary: Breeding resistant cereals to fungal diseases is a long-term alternative to chemical protection against leaf rust, with the Lr55 gene providing effective resistance. Developing molecular markers linked to the Lr55 gene through F2 mapping populations is essential for identifying resistance alleles in wheat genepools.

Summary: This study investigated the resistance levels and yield losses of wheat cultivars under wheat stripe rust infection. The results showed that resistant cultivars had lower yield losses and grain quality losses compared to susceptible cultivars. Disease-resistant cultivars such as XKM18 should be promoted, and susceptible cultivars could be grown in combination with fungicide application under high disease pressure.

Summary: Wheat leaf rust is a common disease that threatens global wheat production, and current mitigation approaches include the use of fungicides and resistance genes. However, the continuous use of resistant varieties leads to the evolution of the pathogen and emergence of new virulent races, causing the demise of resistant cultivars. Diploid wheat accessions have been found to confer resistance through haustorium formation, which is not affected by specific pathogen races. Systemic acquired resistance also provides durable resistance against various pathogens.

Summary: In this study, a stem rust resistance gene SrKN was mapped and characterized from the durum wheat variety Kronos. The gene confers resistance to multiple virulent Pgt races and was mapped to chromosome 2B. Through a large mapping population, SrKN was located within a 0.29 cM region containing nucleotide binding leucine-repeat (NLR) genes that may include the candidate gene. An allelism test suggested that SrKN and the previously mapped Sr9e gene may represent the same gene. SrKN was introgressed into common wheat and completely linked markers were developed for accelerated deployment in wheat breeding programs.

Summary: This study aimed to identify potential wheat lines for yellow rust (YR)-resistance breeding through screening under YR stress using classical analytical tools. The results showed that certain parents and crosses exhibited higher combining ability values for yield traits under YR stress. Cluster analysis revealed divergent classes among the screened genotypes, which shifted under YR stress, indicating variable genotypic response. Factor analysis confirmed genotypes consistently performing under YR stress. The identified genotypes may be used for disease-resistance breeding in wheat.

Summary: The Kazakhstan-Siberian Network on Spring Wheat Improvement brought together 18 research and breeding programs for spring wheat. By analyzing grain ionomics, the study evaluated the impact of environment and genotype on elemental composition and proposed a method to enhance important mineral concentrations in grain. The results showed that the impact of site on element variation was greater than that of genotype, and protein content was positively correlated with multiple elements. The identification of high-quality genotypes contributes to improving the nutritional profile of grain.

Summary: This study investigated the virulence changes of powdery mildew on wheat in different countries and found that many Pm genes have lost effectiveness, with Brazilian isolates showing higher complexity of virulence. Certain high virulence frequencies were linked to specific Pm gene deployments. The isolate collections from Egypt and Turkey identified recently introgressed Pm genes as potential sources of resistance in wheat breeding for other regions.

Summary: Recent technological advances in next-generation sequencing have made DNA sequencing more accessible for species with large and complex genomes, including bread wheat. Despite its importance as a food crop, breeding in bread wheat has been limited by its large polyploid genome. However, after years of effort, draft and reference genome sequences of bread wheat have been released, providing valuable resources for breeding. These advances have also facilitated the use of genotyping arrays in wheat breeding, allowing for fast and reliable characterization of wheat lines. Additionally, gene-editing and genomic selection methods have shown promise in improving important traits in wheat breeding.

Summary: Common bunt is a major wheat disease that causes significant damage to grain yield and quality in the USA and Turkey. Although seed treatment with fungicides is an effective control method, it is forbidden in organic and low-income fields, leading to a preference for planting resistant cultivars. The use of fungicides has resulted in limited efforts to breed resistant genotypes, and the genetic diversity for this trait is low in modern wheat germplasm. However, synthetic wheat genotypes have been found to be an effective source of increasing diversity in wheat germplasm.

Summary: In this study, 115 modern winter wheat cultivars from Central Asian countries were analyzed and compared with germplasms from other regions. The results showed that samples from Kazakhstan and Kyrgyzstan grouped with samples from Russia, while samples from Tajikistan and Uzbekistan grouped with samples from Afghanistan. The genetic diversity index of Central Asian wheat was comparable to that of other regions studied. The SNP markers identified in Central Asian wheat can be used in breeding projects to enhance plant adaptation and stress resistance.
