Figure 1.

Scatterplot matrices for reaction of 35 breeding lines or varieties to soybean white mold (SWM) between drop-mycelium inoculation in greenhouse and field performance (A), between spray-mycelium in greenhouse and field performance (B), and between greenhouse (across inoculation methods), and field performance (C). Pearson's product-moment correlations are shown in the upper panel. Plant mortality (PM) was assessed in greenhouse evaluations (drop- and spray-mycelium), whereas disease severity index (DSI) was assessed in field trials (across Iowa and Wisconsin). Correlation coefficients were significant at 0.01 level for spray-mycelium vs. field performance, while correlation coefficients were significant at 0.001 level for drop-mycelium vs. field performance and greenhouse (across inoculation methods) vs. field performance.
