  • Anthracnose disease caused by Colletotrichum orbiculare, induces severe damage to cucurbits worldwide. Resistance of 112 commercial cultivars of cucurbits to C. orbiculare was evaluated. Seedlings of each cultivar at 2- to 3-leaf stage were inoculated with C. orbiculare KACC 40809 by spraying spore suspension of the fungus at a concentration of $4.0{\times}10^5$ spores/mL. Among the 36 cultivars of cucumber, 'Asiastrike', 'Tongilbaedadagi', 'Daeseon', 'Cheongrokmatjjang', 'Nokyacheongcheong', and 'Asianogak' were moderately resistant and the others were susceptible. All the tested cultivars of melon (33) and watermelon (4) showed highly susceptible response to C. orbiculare. On the other hand, the squash cultivars (17) represented less susceptibility to the fungus than the other cucurbits. Of the squash cultivars, 'Gammirak' and 'Teotbat' were resistant and 12 cultivars were moderately resistant. Among the rootstocks for cucurbits, ten cultivars including 'JjeuyakaEX', 'Nunbusyeo', 'Union', 'RS111', 'Ganggeuntoza', 'Hwangjaetoza', 'NO.8', 'Shintoza', 'Bulpaetoza', and 'Newtype' showed high resistance to the anthracnose pathogen. From the results, the resistant cultivars could be used as sources of resistance to cucurbits anthracnose (C. orbiculare) in the future breeding programs.

  • Immunocapture reverse transcription polymerase chain reaction (IC-RT-PCR) was applied to the detection of Cucumber green mottle mosaic virus (CGMMV), Kyuri green mottle mosaic virus (KGMMV), and Zucchini green mottle mosaic virus (ZGMMV) on Cucurbitaceae crops. These seed-borne tobamoviruses were accurately detected from the infected leaves and seeds by IC-RT-PCR. This method was estimated to be about 100 times more sensitive than ELISA, and also it allowed the direct confirmation of ELISA results by using the captured antigens from a completed ELISA microwell. This convenient and reliable method could be used routinely for large-scale field surveys or seed tests of Cucurbitaceae crops.
