CIMMYT manages humankind’s most diverse maize and wheat collections. Wheat holdings at CIMMYT comprise some 160,000 seed samples from more than 120 countries; the largest unified collection in the world for a single crop. The maize bank contains 28,000 samples of seed, including the world’s largest collection of maize landraces – varieties developed by farmers over decades, centuries or even millennia – along with samples of maize’s wild relatives, teosinte and tripsacum, and of improved varieties.
These seed collections represent the genetic diversity of unique native varieties and wild relatives of maize and wheat and are held under long-term storage for the benefit of humanity in accordance with the 2007 International Treaty on Plant Genetic Resources for Food and Agriculture.
This new data visualization tool was developed by Ernesto Giron in collaboration with Tom Payne, Denise Costich, and Kai Sonder from CIMMYT, inspired by Google Ideas. Data was provided by the International Maize and Wheat Improvement Center (CIMMYT). The visualization includes wheat and maize germplasm sent and 45,172 accessions collected with geographic reference from across the world. This is simply a subset of the 165,409 accessions stored in a database and used for showing the final stats results.
