Abstract | Crown rot disease, caused by the fungal pathogen Fusarium pseudograminearum, poses a significant threat to wheat production due to its destructive impact and with limited resistance found in cultivated wheat varieties. Identifying genetic resistance, the innate ability of plants to resist pathogen infection and proliferation, for crown rot remains a critical challenge owing to the lack of resistance in modern wheat lines. The Watkins wheat landrace collection offers a promising resource with well-documented genetic diversity and genome sequence information. In our study, we created a diversity panel selecting 286 landrace accessions from the Watkins landrace collection and including 63 genotypes from the core set that captures 98% of the collection’s total genetic diversity. Our primary objective is to conduct a Genome-Wide Association Study (GWAS) using resistance data and the whole genome sequence information to identify genetic loci associated with crown rot resistance. We will map the specific genomic regions harbouring the resistance trait and pinpoint the associated Single Nucleotide Polymorphisms (SNPs) for marker-assisted breeding. Additionally, we will leverage the genome sequence data of the Watkins panel, wheat reference line Chinese Spring and pan-genome to uncover candidate genes linked to resistance, facilitating the development of gene-specific markers. Further, the identification of key genes and the molecular pathways linked with crown rot resistance will allow us to develop innovative disease management strategies using advancements in genetic engineering and synthetic biology. |
