Study Name: Gummy Stem Blight Resistance Evaluation for Cucumis/Cucurbit Experiment Type: Field/Greenhouse Field Exp. Design: RCB Exp. Location: Ithaca Year seeded: 06/23/1992 Year tested: 08/30/1992 Comment: Plants inoculated with 100,000 sp/ml inoculum on 8/4 and 8/16. Checks included Freeman cuke(R), Gulfcoast(R), Honeydow(S), and pmm339(S). 7 samples of stem and leaf were evaluated for each of 4 reps per accession. Samples were evaluated on a 1-4(stem) or 1-5(leaf) scale and converted to 1 - 9 scale. Disease rate: on the leaf, 1 = no disease, 2 = 1-25%, 3 = 26-50%, 4 = 51-75%, and 5 = 76-100% of leaf area necrotic respectively, on the stem, 1 = no damage, 2 = single lesion < 10 mm in length or composite < 20 mm, 3 = lesions > 20 mm with girdling of the stem, and 4 = the stem withered, 5 = plant dead.
