摘要

1979年加拿大農業試驗所在Morden,Manitoba地區的試驗場苗圃所種植之菊花，發生很嚴重的萎凋病。使用六種不同的菊花栽培品種當判別植物，來測試分離菌株之病原性。結果顯示，引起當地菊花萎凋之病原菌的病原性與F. oxysporum f. sp. chrysanthemi及F. oxysporum f. sp trachephilum生理小種一號不盡相同。因此，將本病原菌定名爲F. oxysporum f. sp. chrysanthemi 生理小種二號。

A sevcrc natural outbreak of chrysanthemum wilt caused Fusarium oxsporum was observed in a nursery at the Agriculture Canada Research Station, Morden, Manitoba, Canada, in 1979. Pathogenicity test using six differential chrysanthemum cultivars showed that this wilt pathogen (DAOM 175160) is diffcrcnt from the reported chrysanthemum wilt pathogens, F. ovysporum f. sp. chrysanthemi and F. ovysporum f. sp. tracheiphilum race 1. This new race is designated F. oxysporum sp. chrysanthemi race 2.
