Spatial Patterns of Brown Rot Epidemics and Development of Microsatellite Markers for Analyzing Fine-Scale Genetic Structure of <i>Monilinia fructicola</i> Populations Within Peach Tree Canopies

Fig. 3. Plot of dw, an index of disease aggregation, vs. brown rot incidence in five intensively mapped peach tree canopies. dw is calculated based on the cumulative frequency distribution of nearest-neighbor distances among brown rot-affected fruit. Positive values indicate aggregation, whereas negative values correspond to a more regular distribution compared with the random simulation. Data are from early, mid, and late assessment periods during the epidemic as shown in Table 1. Data points in red correspond to the early-maturing cultivar Redglobe 7, which suffered some bird damage to fruit.
