World Vegetable Center biotic stress descriptors for tomato

1.0

These descriptors are being used by the Breeding Unit and the Genetic Resources and Seed Unit (GRSU) of WorldVeg to screen for biotic stress in genebank accessions of tomato and its wild relatives. These descriptors have been published by Mohamed Rakha et al. (2017a;b Genetic Resources and Crop Evolution; https://doi.org/10.1007/s10722-015-0347-y; https://doi.org/10.1007/s10722-016-0421-0).
