Abstract excerpt

KEY MESSAGE: GWAS of 1,273 wheat lines identified a stable MTA 3B_6127880 on 3BS chromosome arm for spot blotch resistance, and the associated candidate genes were differentially expressed in resistant vs. susceptible genotypes. Spot blotch (SB), caused by Bipolaris sorokiniana, poses a threat to global wheat production. We evaluated 1,500 elite wheat lines for SB across two environments to identify genomic...
