Anaerobic germination (AG) is plays important role in submergence resistance which is an important trait for rice production in flood-prone lowland areas. Slow seed germination and delayed seedling establishment due to flooding become major problem for modern sowing methods such as direct seeding and environmental friendly good agricultural practices especially using young seedling age. In total, 137 diverse rice accessions were evaluated for anerobic germination ability. Submergence 1 (SUB1) which is induced ethylene response factors is suggestive because genes belonging to this gene family play a crucial role in rice tolerance to submergence. In this study, haplotype variations of three AG related genes, SUB1 (SUB1A, SUB1B, SUB1C) were examined using whole-genome resequencing data of 137 accessions of rice core set. The new SNPs and InDels found in the exon of the sub1 loci would be useful in developing markers to screen the varieties with strong anaerobic germination ability in the future molecular breeding
