콩에 발생하는 세균병의 종자 오염 및 불마름병과 들불병 저항성 평가 = Syrvey on seed contamination and resistance screen of bacterial pustule and wildfire in soybean

다국어 초록 (Multilingual Abstract)

It has been reported that bacterial diseasees of domestic soybean are bacterial pustule (Xanthomonas axonopodis pv. glycines), wildfire ( Pseudomonas syringae pv. tabaci), bacterial blight (Pseydomonas savastanoi pv. glcines) and bacterial brown spot (Pseudomonas syringae pv. syringae) in Korea. Bacterial pustule had been the most issue in soybean diseases. In recently wildfire also occurrence in soybean and Bacterial blight and bacterial brown spot have been reported to less incidence in Korea. Each bacterial diseases were seed borne and then they caused diseases as orumary casual agent. in this study, direct OCR assay was applied to detect casual agent of bacterial diseases and survey on seed contamination on 44 soybean cultivars and 14 genctic resources in Korea, The pathogens were detected frin the seed samples incubated for 12h with 160rpm shaking. The result of surbey on seed contamination showed that bacterial pustule, wildfire and bacterial blight were detected from some cultivars and genetic resources. We also conducted resistance screening in other to select resistance cultivars of Baterial pustule and Wildfire. we inoculated on 128 cultivars with Baterial pustule and Wildfire respectively. These cultivars were classified through pathoggenecity from 1 to 9. In addition, 35 and 50 resistant cultivars were confirmed against Baterial pustule and Wildfire respectively
