Pre-harvest sprouting (PHS) of wheat poses a major challenge to global food security due its negative impact on grain yield and quality. In the present study, we conducted validation previously published markers or functional associated with PHS resistance in panel 200 cultivars adapted Southeastern European conditions. field experiments four environments Croatia, germination index (GI) was assessed, significant genetic, environmental, genotype-environment interactions were detected. The broad-sense heritability for GI high (0.86), confirming predominant role genetic factors determining resistance. Twenty-two polymorphic SNP analyzed their effects GI, which nine from chromosomes 3A, 3B, 4A, 5A, 7B showed genotypic across environments, especially TaMKK3-A wsnp_Ex_rep_c66324_64493429. addition, marker combinations identified, differences between allele combinations. Overall, this study elucidates basis agro-climatic conditions Southeast Europe provides insights marker-assisted breeding strategies improve
