Mutant stocks and information have been key drivers of maize genetics
cooperation, formalized in August 1932, when maize geneticists attending the
6th International Genetics Congress agreed to establish a cooperative
enterprise to further the advance of maize genetics.

Guide to Maize Mutant Phenotypes, courtesy of M Gerald Neuffer. This resource contains a history of maize mutagenesis, with high quality images and descriptions of mutant phenotypes selected from the Neuffer collection. All derive from EMS treatment of pollen (Coe, EH and Neuffer MG 1978 Maydica 23:21-28). These images are also accessible from MaizeGDB Allele (variation) records. 3000 stocks provided by MG Neuffer are included in the Core Collection of Maize Genetics Cooperation Stock Center (COOP). Download all of Dr. Neuffer's high-resolution Maize Mutant images. These images may be reproduced provided credit is given to Dr. Neuffer. Simple Phenotype Search If the simple search doesn't fulfill your needs, you may want to try the phenotype browser (also found below), which allows you to specify additional criteria and browse through the phenotype records.
This search form allows you to just enter a name or partial name to
quickly retrieve the desired phenotype along with variations and
associated stock.
The example search above will find phenotypes that exhibit purple coloration. Other interesting phenotype searches include cob (cob-related phenotypes), cob diameter (cob diameter phenotypes), and shrunken kernel (directly go to the shrunken kernel phenotype). This search can be executed on every page on the site by utilizing the form in the upper right corner. Choose "phenotypes" from the drop-down menu, enter your search term in the field, and hit return to find the phenotype you're looking for. You can also browse through the phenotypes visually by viewing images associated with various phenotypes. Advanced Search This tool allows you to specify detailed search criteria, much like the other advanced searches, but the output looks slightly different; it is intended to allow you to dig more directly into the data rather than just visiting individual records.
Search MG Neufer Mutant Descriptions This search allows you to search for descriptions of mutant phenotypes. These descriptions were provided by MG Neuffer. Phenotype Image Search
The site includes a large collection of phenotype images. You can search through the
images below; clicking on the image will enlarge the image, and clicking on the links
next to the image will provide details on that phenotype.
This search form allows you to just enter a name or partial name to quickly retrieve the desired phenotype along with variations and associated stock. Search and Browse Phenotypes in Stock Collections Stocks Distributed by the Maize Genetics Cooperation Stock Center The Core COOP Collection
