Select the tab for the type of search. Each tab has everything you need to do to perform that type of search.

(Results of more than 500 will not return images.)

This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as

PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.

The more information you provide, the better the search will be.

0GSOR 301379CocodrieOryza sativa L. United StatesGSORPANICLENot Available2007DEVELOPED2011Genetic materialTo represent the range of genetic diversity found in cultivated Asian rice, 409 Oryza sativa accessions were selected from around the world. They cover the full geographic and ecological range of rice- from Indonesian paddy terraces, to the harsh upland soils of northern Thailand; from rapidly rising Chinese riverbeds to African mangrove environments. The 409 O. sativa accessions represent all five sub-populations of rice: indica, aus, tropical japonica, temperate japonica and Group V (sometimes called aromatic or basmati) varieties. The diverse set of rice accessions also includes a wide range of important economic phenotypes, including varieties known to be resistant to diseases and insects or tolerant to flooding, drought, high salt concentrations, low mineral nutrition. There are also varieties with varying cooking qualities, such as different grain colors, lengths, textures, and fragrance. The accessions were chosen to build upon several previous studies, including a subset of the varieties used by Garris et al. (2005) to evaluate sub-population structure in O. sativa. Approximately 200 of our accessions overlap with the 3,000 analyzed for diversity within the internationally-funded Generation Challenge Program (GCP) and 159 overlap with the USDA-ARS rice core collection. This Rice Diversity Panel was fingerprinted with 36 simple sequence repeat (SSR) markers and evaluated for 18 agro-morphological traits. The rice diversity panel with the accompanying genetic and phenotypic information provides a valuable foundation for association mapping, understanding the basis of both genotypic and phenotypic differences within and between subpopulations, and rice improvement programs.1882997GSOR 301379
