Rice Diversity Panel 1
headline bar

The Rice Diversity Panel 1 (RDP1) is a collection of 421 purified, homozygous rice (Oryza sativa L.) accessions (GSOR 301001 through GSOR 301421; GSOR 312001 through 312020) representing the broad range of genetic variation within O. sativa.


The accessions include both landraces and elite rice cultivars, which were classified into five subpopulation groups, including indica (95 accessions) and aus (60), which belong to the Indica varietal group, and tropical japonica (106), temperate japonica (111), and aromatic (Group V) (16) which comprise the Japonica varietal group. Thirty-three accessions are classified as admixtures because they shared <60% ancestry with a single group.
