香石竹细菌性枯萎病（Pseudomonascarylli）是香石竹（Dianthuscaryophyllus）在日本的主要病害之一。它导致在温暖地区种植的康乃馨严重减产。然而，在香石竹中进行抗此病害的育种很少。因此，277个香石竹品种的抗青枯病，采用切根浸泡法，接种浓度为107 cfu（菌落形成单位）/ml。高感品种207个（74.7%），抗病品种3个（Wiko、Numbers和Sandrosa）。
Bacterial wilt (Pseudomonas caryophylli) is one of the most important and damaging disease of carnations (Dianthus caryophyllus) in Japan. It causes serious crop losses in carnations grown in the warm districts. However, breeding for resistance to this disease in carnation has been rarely carried out. Therefore, 277 carnation cultivars were screened for resistance to bacterial wilt by using the cut-root soaking method with an inoculum concentration of 107 cfu (colony-forming units)/ml. Two hundred seven cultivars (74.7%) were highly susceptible, whereas 3 cultivars, 'Wiko', 'Nocto', and 'Sandrosa' possessed adequate resistance.
