Accession details

Core Accession from CIor 12510. The Core Collection containing about 10% of the whole NSGC Rice Collection was assembled by stratified random sampling method in 2002, evaluated comprehensively for 25 characteristics and proven to be highly representative of the whole collection. Information drawn from the Core Collection can effectively be used to assess the whole collection with 88% certainty. A single plant was selected from each Core accession in 2006 and bulk seed from the single plant selection produced in 2007 is deposited in the GSOR DNA extracted from the selected plant has been analyzed with one indel marker and 71 SSR (Single Sequence Repeat) markers that cover the entire rice genome about 30 cM apart. A Mini-Core Collection containing about 10% of the Core Collection has been developed and fingerprinted with 155 SSR markers, averaging one marker every 10 cM in the genome. <p>Because the Core and Mini-Core were developed from single-plant selections from the NSGC accessions which may be phenotypically variable, there is the possibility that the GSOR seed sources are not exactly the same as the NSGC sources.
