The MaizeGDB Pedigree Viewer

The MaizeGDB Pedigree Viewer is developed to display pedigree relationships between maize varieties in a network representation. The Viewer is based on a pedigree network of 4706 maize varieties that are currently available in the MaizeGDB Stock Pages. The tool allows the user to apply a number of filters, select or upload their own breeding relationships, center a pedigree network on a maize variety, and display the shortest path(s) between two maize varieties on the pedigree network.
