The International Rice Research Institute (IRRI) has introduced the Released Variety Panel (RVP), a new collection that adds over 130 sequenced rice varieties to the International Rice Genebank. This panel features popular and climate-resilient varieties currently cultivated by farmers. The initiative aims to improve the chances of research findings effectively reaching agricultural fields, ultimately promoting the adoption of enhanced rice varieties among farmers.
Scientists and breeders can access these seeds through the International Rice Genebank (IRG), while the genetic sequences are available on the SNP-Seek Database. The RVP includes a range of varieties that are popular in specific regions, making it a practical tool for researchers looking to connect scientific advancements with agricultural applications.
The development of the RVP stems from research projects like the High-Density Rice Array (HDRA) and the 3,000 Rice Genomes Project (3k RGP). These initiatives have allowed scientists to better understand the genetic diversity within IRG’s collection and to identify valuable traits and genes. Notably, the traits found in modern rice varieties can differ from those in earlier diversity panels.
Incorporating accessions that are currently cultivated by farmers, the RVP is poised to facilitate the translation of research findings into tangible benefits for agricultural practices. The project has garnered support from various organizations, including the Bill and Melinda Gates Foundation, the Zegar Family Foundation, the Chinese Academy of Agricultural Sciences, and the Shenzhen government in China. The Crop Trust has also played a crucial role in maintaining the Genebank seed collections.
Accessing the RVP
Researchers interested in the RVP can view the list of available varieties and request seeds via the Genesys platform. A new option through the GRIN-Global platform will soon enable users to create profiles, search for accessions, and submit seed requests. To process a seed request, authorized individuals must agree to the Standard Material Transfer Agreement, provide an import permit, and obtain a phytosanitary certificate. Processing requests is expected to take around six weeks, with potential fees depending on the organization’s requirements.

In addition to the seed requests, SNP sets for the released varieties are currently available in the SNP-Seek Database, with a consolidated version set to be released soon. Additional phenotypic data related to the RVP can be accessed on Zenodo, an open-source research data repository.
Preserving Rice Biodiversity
The International Rice Genebank houses over 132,000 accessions, making it the largest collection of rice genetic diversity globally. Countries from around the world contribute their rice varieties to IRRI for preservation and public use. However, traditional varieties and wild rice species are facing threats from genetic erosion and habitat destruction.
IRRI is committed to preserving rice biodiversity as part of a global strategy for conserving genetic resources. This effort is in collaboration with national programs and organizations worldwide, including the CGIAR Research Program for Managing and Sustaining Crop Collections.
As rice remains a staple food for half of the world’s population, addressing the challenges of climate change and food security is paramount. The RVP serves as a valuable resource in this ongoing effort to improve rice production and ensure sustainable agricultural practices for the future.
