Rice Core Collection of Japanese Landraces

The Collection consists of 50 accessions. It retained 95% of SSR alleles detected in about 240 accessions selected based on the passport data from the whole Japanese landrace collections (about two thousands accessions) maintained at the NARO Genebank.

The multiple genome browser TASUKE+ provides the genome-wide variant information*1.
