Interactions between alfalfa and Verticillium albo-atrum were examined in terms of the following aspects:growth of V. albo-atrum on callus;growth of callus on the medium containing culture filtrate of V. albo-atrum and production of antifungal substances in callus treated with cell wall components (elicitor) from V. albo-atrum. Mycelial growth of V. albo-atrum was likely to be suppressed on the callus from resistant cultivars (Vertus and 5444), accompanied by strong browning. The growth of callus from Vertus (resistant, R) and Kitawakaba (susceptible, S) were vigorous on the medium containing 0.5 or 1% culture filtrate, while those from 5444 (R) and Europe (S) were inhibited. Antifungal substances were detected in all cultivars treated with cell wall components, with concentrations being higher in resistant than in susceptible cultivars. These results suggest that antifungal activity in the callus extracts indicated by the inhibition of germ tube elongation of fungal conidia is the best criterion for the selection of resistant cultivars.
