- Genetic Diversity
The Gramene Genetic Diversity database contains SSR, RFLP and SNP allelic data and passport descriptions for rice, maize and wheat germplasms. It also holds phenotypic data for rice and maize. The database can be searched by germplasm accession number, accession name or marker/locus name. For example, in the rice database you can search for germplasm accessions "IRGC 3575", PI 400604, or RA4969, or marker RM22. Please specify the species of your interest from pull-down menu before you press the submit button. For search tips, please read the help document. For the advanced search, see Gramene's Diversity Advanced Search: Highly-Flexible User Front-End Built on GDPC Middleware.

Genetic Diversity Search Options
Home Page: Introduction and Quick search (above) - Search the Genetic Diversity database by keyword (see Help document for tips). In addition to this search interface, we also host several search scripts from the Panzea project:
Advanced Search: To perform advanced queries, use the Java-based GDPC Advanced Search Tool. The advanced search provides access to genomic diversity data such as SNPs, SSRs, sequences, etc. and phenotypic data that may be collected in field, genetic, or physiological experiments. Complex queries can be executed, data saved in various formats, data integrated from multiple sources, etc. Help
Help Presents an overview on how to search the Genetic Diversity database and lists explanations of field names. Tutorial More in-depth than the help pages, use the tutorial for an exaple of using the database, see how it integrates other datasets, and get tips to increase your data search efficiency. Advanced Search Help January 2007 Gramene Newsletter Article on the Diversity advanced search, Gramene's Diversity Advanced Search: Highly-Flexible User Front-End Built on GDPC Middleware presents an example. FAQ Frequently Asked Questions - see what questions users have asked, and get the developers answers. Release Notes For more information about the most recent release. Download
The data can be downloaded in bulk from our FTP site. Also available is association data from the TASSEL program.
