Identification of Soybean Accessions Resistant to <i>Macrophomina phaseolina</i> by Field Screening and Laboratory Validation

Fig. 3. Total precipitation (cm) and maximum air temperature (°C) shown for the months of April through October for Missouri in 2008 (A) and 2009 (B); for Illinois in 2008 (C) and 2009 (D), and for Tennessee in 2009 (E) and 2010 (F). Disease severity rating on a scale of 1 to 5 was recorded in the five environments (A-E). The CFU determination was made in 2010 (Fig 1 F). A dashed line at 35°C across the graph compares the temperature differences among years.
