Latency of Botrytis cinerea Prs.: Bunch rot of grapes in Mendoza, Argentina. Estimated Fst value comparing all French isolates together as only one population. Roudet, and V Rossi, b. The Genepop software estimates the P value for Fisher’s exact test using a Markov chain.

All the analysed isolates were classified as Group II according to the most recent proposed classification and showed a high degree of genetic diversity, with 14 different haplotypes. The Fst values between the Cnierea subpopulations were low as was observed for other comparisons of sites within a viticulture region.
