“…To evaluate LTG, seeds from the 137 rice accessions were germinated under two conditions: 13 °C for 15 days (treatment) and 28 °C for 7 days (control) (Cruz and Milach 2004;Hyun et al 2017). Prior to planting, all seeds were rinsed with water, sterilized in 1% sodium hypochlorite solution for 10 min, and rinsed three times with deionized distilled water.…”

“…Temperate japonica rice varieties are usually grown in East Asian countries such as Korea, where the water temperature in the field during the sowing season is often below 15 °C. Therefore, tolerance to low temperatures during germination is important for rapid, uniform crop establishment (Hyun et al 2017). Previous studies of low temperature germinability have revealed the complex inheritance of the trait (Miura et al 2001).…”

In this study, relative germination percentage (RGP) and delayed mean germination time (DMGT) were measured in various rice accessions at the germination stage and carried out association analysis to identify candidate genes related to low temperature germination (LTG) using a natural population comprising 137 rice cultivars and inbred lines selected from the Korean rice core set. Genome-wide association study using ~ 1.44 million high-quality SNPs, which were identified by re-sequencing all rice collections, revealed 48 candidate genes on chromosome 10 and 55 candidate genes on chromosome 11 in the high peak SNP sites of associated loci for RGP and DMGT, respectively. By detecting highly associated variations located inside genic regions and performing functional annotation of the genes, we detected 23 candidate genes for RGP and 18 genes for DMGT for LTG. In addition, the haplotype and sequence analysis of the candidate gene (Os10g0371100) with RGP trait and the candidate gene (Os11t0104240-00) with DMGT revealed correlation between sequences of functional variations and phenotypes. Several novel LTG-related candidate genes previously were known for the function during rice germination and uncovered their substantial natural variations. These candidate genes represent valuable resources for molecular breeding and genetic improvement of cold tolerance during rice germination.
