Summary: Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a destructive disease in wheat worldwide. Developing and using resistant cultivars is an effective method to combat this disease. A genome-wide association study identified markers closely linked to stripe rust resistance, which can be used for marker-assisted selection to enhance rust resistance in wheat breeding programs.

Summary: Triticum aestivum L. is an important strategic crop that provides essential nutrients, energy, and protein for humans and animals. Genetic characterization of wheat genotypes can aid in designing plant breeding programs, particularly for selecting genotypes resistant to stress conditions. This study analyzed marker resistance for brown rust in wheat and determined the genetic characterization of 96 genotypes using SSR and ISSR loci. The results revealed genetic diversity, resistance alleles, and clustering of wheat varieties. The findings highlight the importance of selecting genetically diverse and resistant genotypes for future breeding programs.

Summary: This study evaluated the resistance of 70 uncharacterized wheat cultivars and promising lines with unknown leaf rust resistance genes (Lr genes) to Kazakhstani Puccinia triticina (Pt) races. Thirteen wheat genotypes (18.6%) exhibited high resistance at both seedling and adult plant stages, with breeding materials from international nurseries showing higher resistance. Molecular screening identified nine Lr genes in 47 genotypes, with Lr37, Lr34, and Lr46 being the most common. These findings will facilitate wheat resistance breeding programs in Kazakhstan.

Summary: This study conducted a genome-wide association study to identify genetic loci controlling ferulic acid content in wheat grains. Eight major loci were discovered, each explaining approximately 10% of the phenotypic variances. The favorable alleles of these loci have significant accumulative effects on ferulic acid content. Additionally, two SNPs closely associated with ferulic acid content were successfully converted to flexible kompetitive allele-specific PCR (KASP) markers for marker-assisted selection in breeding.

Summary: A genetic framework for salinity tolerance in wheat at the reproductive stage was revealed using genome-wide SNP markers and major adaptability genes. The trait-associated loci were used to predict phenotypes, and their effects were validated. The study also identified loci associated with salt tolerance in synthetic-derived wheat lines and compared them to modern bread wheat lines. Functional genes related to salt tolerance were uncovered, and a genetic interaction network was constructed to reveal correlations among the investigated traits.
