A key problem for scientists is the integration of diverse and dispersed biological data and their analysis using diverse analytical tools. We developed GenDiversity, which is a query and analysis application combining genotyping and passport data from diverse crop data sources. GenDiversity, is a Web application for

• querying decentralized genotyping data from different databases
• combining two or more different genotyping studies
• converting outputs to different file formats for diversity analysis: DARwin (Perrier 2006), Convert (Glaubitz 2004), Structure (Falush et al. 2007), Nexus (Maddison et al. 1997)
• filtering by passport data
• computation of allelic frequencies
• computation of linkage disequilibrium
• checking for duplicates.

The public data comes from

• TropGENE-DB (Ruiz et al. 2004)
• GCP central repository, which stores all the data produced by the GCP projects
