IRRI Launches RVP with Over 130 Sequenced Rice Varieties to Increase Crop Research

The International Rice Research Institute (IRRI) has launched a new resource called the Released Variety Panel (RVP), which features over 130 sequenced rice varieties. These seeds, available upon request through the International Rice Genebank (IRG), are intended for scientists and breeders. The genetic sequences can also be accessed via the SNP-Seek Database, making it easier for researchers to study and utilize these rice varieties.

This initiative, led by IRRI’s Rice Breeding Innovations department, is designed to promote the adoption and awareness of improved rice varieties that are already cultivated by farmers. These varieties include those that are especially popular in specific rice-growing regions or are better adapted to withstand the effects of climate change. The RVP complements existing initiatives like the High-Density Rice Array (HDRA) and the 3,000 Rice Genomes Project (3K RGP), which have significantly contributed to upstream research into rice genetics.

While previous research has primarily focused on IRG's extensive collection of germplasm and landraces, the RVP provides access to more modern rice varieties. These varieties have been bred for improved traits, which differ from those in diversity panels. This panel helps bridge the gap between cutting-edge rice research and real-world agricultural impact. By using RVP accessions as benchmarks, researchers can ensure that their findings have a higher chance of reaching farmers' fields and improving crop yields and resilience.

The development of the RVP was supported by numerous partners and donors, including the Bill and Melinda Gates Foundation, the Zegar Family Foundation (New York University), the Chinese Academy of Agricultural Sciences (CAAS), and the Government of Shenzhen, China.

To request seeds, users can access the RVP list through the Genesys platform, add selected varieties to their list, and submit a request. Alternatively, the GRIN-Global platform will soon offer another method for seed requests. The process typically involves agreeing to a Standard Material Transfer Agreement (SMTA), submitting an import permit and a phytosanitary certificate, and possibly covering some costs related to the Genebank.

Additionally, SNP sets for these varieties can be found in the SNP-Seek Database. Phenotype data generated by students in collaboration with IRRI is also available on Zenodo, offering further valuable insights for researchers.
