Correlation between the pairwise genetic differentiation (Q_ST) of mancozeb tolerance in Alternaria alternata populations and the pairwise difference in annual mean temperature in the collection sites. Mancozeb tolerance of isolates was measured with relative growth rate (RGR) of the isolates in the presence of the fungicide and in the absence of the fungicide. Pairwise difference in annual mean temperature was estimated by dividing the absolute difference in annual mean temperature in two collection sites with the sum of annual mean temperature in the two sites
