Abstract: Botrytis cinerea and Botrytis elliptica were determined for infection of different Lilium cultivars, aiming at clarification of the pathogenicity of the two Botrytis species. The main cultivated lily varieties in Yunnan Province were collected and in vitro inoculated with the two Botrytis species. The results showed that lesions caused by B. cinerea in petals occurred earlier than that in leaves. On the other hand, the occurrence time of the lesions caused by B. elliptica in petals varied in different lily cultivars (48 h or later). There was no lesion caused by B. elliptica on leaves of ‘Conca D’or’ after 96 h inoculation, while the lesion on petal caused by B. elliptica was observed after 48 h inoculation, which suggested that the leaves of ‘Conca D’or’ were more resistant than the petals to infection by B. elliptica.
