Abstract
Salinity stress is one of the most severe abiotic stresses that affect agricultural
production. Genome wide association study (GWAS) has been widely used to detect
genetic variations in extensive natural accessions with more recombination and higher
resolution. In this study, 206 barley accessions collected worldwide were genotyped
with 408 Diversity Arrays Technology (DArT) markers and evaluated for salinity stress
tolerance using salinity tolerance score – a reliable trait developed in our previous work.
GWAS for salinity tolerance had been conducted through a general linkage model and a
mixed linkage model based on population structure and kinship. A total of 24 significant
marker-trait associations were identified. A QTL on 4H with the nearest marker of bPb-
9668 was consistently detected in all different methods. This QTL has not been reported
before and is worth to be further confirmed with bi-parental populations.
