Germplasm Search

The maize germplasm pool includes teosintes, native maize landraces of Latin America, and inbred lines used in plant breeding.

From this search utility you can download information about germplasm used in this project, including germplasm type, countries of origin, geographical parameters of the lines' collection locations, and where the seed can be obtained.

To obtain this information, use the search form at the right. To obtain a complete list of the germplasm used in our project, leave all the search parameters in their default state, choose the output format you would like, and click Submit. To change the sorting order of the resulting output, modify the 'Sort by' parameters before clicking Submit. To limit the search by your criteria of interest, use the text input fields and drop-down menus to specify your criteria.

The text input fields (Accession, Source, Racename, State/Province, Collector, Collection) are set by default for an exact match ('equals'). These searches can be modified to find records either containing the text that you enter ('contains') or matching the text/wildcard combination that you enter ('matches'). The wildcard '?' stands for a single character while '*' stands for zero or more characters. The search is not case-sensitive.

Output tables in HTML format will appear below the search form on a refreshed page, and will contain a subset of the available fields in the database. For a complete table, including information on population, locality, elevation, longitude and latitude, choose any format other than HTML. Alternative formats for downloading and saving the complete result table include Excel or three different text formats: fixed-width, comma-separated or tab-delimited.
