Mini-Core Collection
headline bar

The Mini-Core collection was developed as a smaller representative subset of the Core collection and consists of 217 accessions. The collection was developed from single-plant selections from the NSGC accessions. The GSOR seed source are not the same as the NSGC source and may be phenotypically variable. The Mini-Core collection was Next-Generation Sequenced in 2016 by Wang et al. 2016. The raw reads were downloaded, and SNPs called in-house.

Order accessions from the Mini-Core Collection - Please contact the GSOR at gsor@ars-grin.gov for information about requesting this germplasm.  The general distribution amount is 3 grams per accession.

 

We request that the source of these rice accessions be acknowledged when used as a resource for research publications or cultivar development. Suggested acknowledgement: Rice accessions (Oryza sativa) were obtained from the USDA-ARS, Dale Bumpers National Rice Research Center, Stuttgart, Arkansas, Genetic Stocks Oryza Collection (www.ars.usda.gov/GSOR).
