영문 초록

The SUBMERGENCE 1 (SUB1) locus, conferring tolerance to complete inundation, was identified, and gel-based DNA markers, AEX1 and GnS2, were previously developed for marker-assisted breeding (MAB). However, a high throughput and high specific method, at low cost, is still required to detect Sub1 alleles. Kompetitive Allele Specific PCR (KASP) markers enable high throughput analysis for a large number of seeds, as well as detection of both alleles, in a single reaction. In this study, we developed KASP markers that can distinguish specific alleles at Sub1A loci based on single nucleotide polymorphisms (SNPs). Marker validations were carried out by genotyping of a segregating population with the developed KASP markers. The results from KASP assay and gel-based marker analysis were consistent for Sub1A alleles. KASP markers developed for Sub1A would be helpful due to high accuracy, low cost, and a high throughput genotyping feature in MAB.
