Rooted cuttings of 57 cultivars of chrysanthemums from a commercial propagator were culture-indexed and found to be free of the Fusarium wilt pathogen Fusarium oxysporum f. sp. chrysanthemi. The vast majority of cultivars were highly resistant to both F. oxysporum f. sp. chrysanthemi and f. sp. tracheiphilum; however, Excel, Foxy, Luv, and Fortune were highly susceptible and Applause, Circus, Remarkable, and Tempter were susceptible to F. oxysporum f. sp. chrysanthemi. Foxy was highly susceptible and Luv was susceptible to F. oxysporum f. sp. tracheiphilum.
