The FDR corrected threshold (− log10 (p-value) ≥ 4.5) was used to identify significant SNP–trait associations. a: Minor allele frequency. TTN: Total tiller number; FTN: Fertile tiller number; Normal: BLUEs value across all normal irrigation conditions; Stress: BLUEs value across all drought stress conditions; All: BLUEs value based on 6 environmets under normal and drought stress conditions.
