Fig. 1. Lesion length (cm) from 3 to 14 DAI on soybean plants that were 5-, 6-, and 7 wk old at inoculation. A partially resistant cultivar, NKS19-90, and susceptible cultivar, Williams 82, were inoculated with S. sclerotiorum isolate 105HT, incubated for 48 h, and postincubated at 25 ± 1°C to observe disease development. FLSD values were 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, and 1.3, respectively, for 8, 9, 10, 11, 12, 13, and 14 DAI.
