Cultivar Resistance of Korean Breeding Cut-Rose against Crown Gall by Agrobacterium tumefaciens Evaluated by an In Vitro Inoculation.

ABSTRACT: Rose crown gall caused by Agrobacterium tumefaciens is a major disease that damages the production of cut-roses in Korea. The effective prevention methods for this disease include the use of resistant varieties. This study was conducted to evaluate the resistance of 58 Korean cultivars and six foreign cultivars to crown gall disease with nodal explants in vitro. Among 180 A. tumefaciens strains, pathogenic strain RC12 was selected as an inoculant strain. The strain RC12 was identified based on characteristics of some selective media, pathogenicity test, and polymerase chain reaction analysis. Forty rose cultivars formed tumors on explants inoculated with A. tumefaciens RC12. However, 24 cultivars, including 22 Korean cultivars and 2 foreign cultivars, showed resistance to A. tumefaciens RC
