The methodologies for genotyping and high throughput automated platforms for the production of type-omics (genomics, transcriptomics, protected omics ...) have greatly increased over the last few years and are now available to analyze the expression of genes of plants in several environmental conditions. However, a break of conceptual and technical services, non-destructive characterization and dynamic phenotypes, at the organ or plarite, has hundreds of related genotypes (Broadband) remains the limiting factor for the discovery of new characters or new varieties. This systematic exploration of diversity. Genetics within a species or between species requires platforms to characterize and automatically varied environments (biotic and abiotic) the phenotype of a large number of individuals from populations of mutants mapping, crosses and collections. The challenge is to achieve the flow rates in the production data from phenotyping, genotyping similar ones. The quantitative characters being observed - the components of the air architecture such as the number, size, shape and position of the leaves, for example - they require extremely precise control of changes in environmental parameters. Phenotyping Broadband is essential for genetic analysis of functional genes as specific particular reduces the time required for the discovery of new genes likely to generate important agronomic applications, such as changing the content of molecules, the composition and size of seeds and fruits, or tolerance to drought
