Abstract
The behavior of rice varieties under natural environments in fields often differs from the expected one. For developing
varieties, breeders give then a particular importance to multi-local field screening to confirm the resistance of their
germplasm. We assembled 81 accessions e.g. blast differential, traditional and improved varieties and tested them for
resistance to blast (Pyricularia grisea) in eight African hot spots under different ecologies. We thus expected to identify
accessions and genes or gene pyramids that provide durable resistance locally or across sites.
