Implication

Genome-wide association study identified SNP markers for resistance to Stemphylium vesicarium in spinach, suggesting genomic prediction can enhance selection accuracy.

Key Points

Identified four significant SNP markers associated with Stemphylium leaf spot resistance in spinach.
Used genome-wide association studies with disease severity index data across 311 diverse spinach genotypes.
Genomic prediction models revealed higher accuracy with GWAS-derived SNP sets, achieving r-values of 0.45 and 0.51.
Supports marker-assisted selection as a potential strategy for developing resistant spinach cultivars.
