Résumé
Although widespread in nut orchards abroad and in other French crops such as vineyards, dieback disease has been recently reported in France on walnut trees, causing severe yield losses since 2015 onwards. The emergent nature of this disease encouraged us to explore its sources and pathways, based on a population genetic study. This dataset contains genotypes of B. dothidea and N. parvum strains collected from French walnut trees (both symptomatic and asymptomatic walnut husks and twigs; 381 strains), French vineyards (48 strains) , Spanish walnut trees and Californian walnut and almond trees (24 strains). Genotypes were obtained the microsatellite marker sequencing technology developed and implemented at the Genome Transcriptome Facility of Bordeaux. A total of 11 loci were used for B. dothidea, and 27 loci for N. parvum. The dataset also contains metadata (e.g. collection date, origin) on each strain. For each species, the genotype tables are constructed as follow: the name of the strains (1st column); the name of the loci identified as PROJECT-SPECIES-NUMBER OF THE LOCI (1st line); and the allele for each locus coded using a three-digit number. A different code represents a different allele in terms of microsatellite repeats. An allele coded with "0" corresponds to a missing data.
