The goal of the center is to acquire, maintain, and make available stocks containing all known allelic and cytological variation in corn and information about them.
Any available stock is sent upon request without charge.
The MGC-SC is the main repository for corn mutants research by cooperators worldwide. The total collection approaches 100,000 individually pedigreed samples. The bulk of the collection consists of several hundred symbolized genes, together with many additional gene combinations and other heritable variants. Many of the stocks are maintained in forms or combinations suitable for specific research uses. Mutant genes that generate unbalanced chromosome complements are also maintained.
