Rice is one of the most important cereal crops, providing the daily dietary intake for approximately 50% of theglobal human population. Here, we re-sequenced 259 rice accessions, generating 1371.65 Gb of raw data.Furthermore, we performed genome-wide association studies (GWAS) on 13 agronomic traits using 2.8 millionsingle nucleotide polymorphisms (SNPs) characterized in 259 rice accessions. Phenotypic data and best linearunbiased prediction (BLUP) values of each of the 13 traits over two years of each trait were used for the GWAS.The results showed that 816 SNP signals were significantly associated with the 13 agronomic traits. Then wedetected candidate genes related to target traits within 200 kb upstream and downstream of the associated SNPloci, based on linkage disequilibrium (LD) blocks in the whole rice genome. These candidate genes were furtheridentified through haplotype block constructions. This comprehensive study provides a timely and importantgenomic resource for breeding high yielding rice cultivars.
