Rice, as one of the most important staple crops, its genetic improvement plays a crucial role in agricultural production and food security. Although extensive research has utilized single nucleotide polymorphisms (SNPs) data to explore basis agronomic traits rice improvement, reports on other types variations, such insertions deletions (INDELs), are still limited. In this study, we extracted INDELs from resequencing 148 improved varieties. We identified 938,585 found that length variation increases, number variations decreases, with 89.0% being 2–10 bp. The highest was chromosome 1, while least 10. were unevenly distributed across genome, generating total 33 hotspot regions. 47.0% located within 2 kb upstream downstream genes. Using phenotypic five (heading date, flag leaf length, width, panicle number, plant height) along INDEL perform genome-wide association study (GWAS), 6,331 significant loci involving 157 cloned Haplotype analysis candidate genes revealed affecting functional genes, OsMED25 OsRRMh related heading MOC2 height. Our work analyzed patterns associated traits. These results will provide valuable material resources for rice.
