Figure 1. Frequency distribution plots of F 2 data for the four watermelon families (resistant PI accessions by susceptible cultivars of Citrullus lanatus var. lanatus and citroides) screened for resistance to gummy stem blight in greenhouse and field tests in North Carolina (2002-2003). Disease assessment scale adopted for the screening: 0 = no disease; 1 = yellowing on leaves (suspect of disease only); 2 to 4 = symptoms on leaves only; 5 = some leaves dead, no symptoms on stem,; 6 to 8 = symptoms on leaves and stems; 9 = plant dead. 127
