Abstract

14 Vitis spp., 7 other Vitaceae and 73 cultivars belonging to Vitis vinifera and V. labrusca were screened under natural and artificial inoculation conditions for their resistance to grapevine bacterial canker disease (GVBCD). Among the Vitis species, V. vinifera was highly susceptible, while others were either resistant or highly resistant. Vitaceae other than Vitis were highly resistant. Among the V. vinifera cultivars, seedless ones were more susceptible than seeded vines. Among seedless cultivars, coloured were more susceptible as compared to white ones.

Gegen Reben-Bakterienbrand resistente Genotypen der Gattung Vitis

14 Vitis spp., 7 andere Vitaceen und 73 Sorten von V. vinifera bzw. V. labrusca wurden unter natürlichen und künstlichen Inokulationsbedingungen auf ihre Resistenz gegen Bakterienkrebs der Rebe (GVBCD) geprüft. Von den Vitis-Arten war V. vinifera hochanfällig, während die anderen Species resistent oder hochresistent waren. Die Vertreter der übrigen Vitaceengattungen waren alle hochresistent. Bei den geprüften V. vinifera-Sorten waren kernlose Typen anfälliger als kernhaltige. Unter den kernlosen Sorten waren wiederum die rotbeerigen anfälliger als die weißen Sorten.
