Summary: In this study, the high-resolution map of the wheat rust resistance gene Yr78 was generated, and the candidate region associated with this gene was identified. The HI haplotype associated with Yr78 was found in common wheat cultivars, and two molecular markers for this haplotype were developed for the deployment of Yr78 in wheat breeding programs.

Summary: This study identified the chromosome locations of leaf rust resistance genes in the hard red spring wheat cultivar AC Taber, with significant QTL effects for resistance found on chromosomes 2BS and 3BS. The genes on these chromosomes were found to be associated with adult plant resistance genes Lr13 and Lr74. Newly developed KASP PCR markers linked to these regions can be used for marker-based selection of these resistance genes.

Summary: The spring wheat line 'Copio' shows high level of resistance to leaf rust pathogen. Seven QTL for resistance to leaf rust were identified in 'Copio', with three QTL consistently expressed in all environments. Additionally, several recombinant inbred lines carrying a combination of resistance alleles were identified, which significantly reduced leaf rust infection.

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: A multi-year evaluation of the Vavilov wheat diversity panel identified new sources of adult plant resistance to stripe rust. Genome-wide association studies revealed key genomic regions influencing resistance, including seven novel loci. These findings are important for broadening the genetic bases of YR resistance in modern wheat varieties.

Summary: In this study, two RIL populations were used to detect novel genomic regions associated with rust resistance. Stable QTLs were identified for yellow rust (YR) and leaf rust (LR) resistance, and candidate genes involved in host response regulation were identified. The findings provide valuable information for marker-assisted selection in breeding rust-resistant varieties.

Summary: In this study, a new race-specific seedling stripe rust resistance gene, YrK, was identified on wheat chromosome 5BL through genotyping-by-sequencing and bulked segregant RNA sequencing. Functional molecular markers for YrK were developed. Additionally, four adult plant resistance (APR) loci were mapped on wheat chromosome arms 1BL, 2AS, 2BS, and 4AL. The findings of this study provide valuable resources for the development of rust-resistant wheat varieties.

Summary: Wheat leaf rust caused by Puccinia triticina was the most prevalent among the three rusts in wheat-growing areas of India, Bhutan, and Nepal. A total of 33 pathotypes were identified, with two pathotypes accounting for 79.46% of the population. Most Indian wheat germplasm varieties possessed a high degree of resistance to leaf rust caused by the majority of identified pathotypes.

Summary: This study surveyed wheat growing areas in Northeast India, Nepal, Bhutan, and Bangladesh and identified five new pathotypes of Puccinia triticina. These pathotypes exhibited diverse virulence on leaf rust resistance genes, with some Indian wheat cultivars' resistance genes being ineffective against the new pathotypes. In contrast, other resistance genes were effective against these pathotypes. Based on SSR markers, these pathotypes were distinct and could be categorized into two groups.
