Abstract
Callus cultures derived from internodal segments of two cultivars of carnation susceptible to Fusarium oxysporum f.sp. dianthi were successfully used for in vitro selection for resistance to this pathogenic fungus. Resistant lines were selected by culturing calli on growth medium containing various concentrations of the culture filtrate of F. oxysporum f.sp. dianthi. Resistant calli obtained after two cycles (25 days/cycle) of selection were used for plant regeneration. About 32% of the plants regenerated from the resistant calli had acquired considerable resistance against the pathogen in the field. No phenotypic variation was observed in the selected regenerates.
