摘　　要：对云南各主要植胶区采集、分离得到的7个橡胶树多主棒孢菌株进行致病性测定,获得强致病力菌株DF4。分别用菌丝体接种鉴定、分生孢子悬浮液接种鉴定和粗毒素接种鉴定相结合的方法,对云南植胶区的9个主栽橡胶品种进行抗病性评价。结果表明,不同接种体或不同接种方法获得的抗性评价结果大致相同,但是也存在一定的差异。Pathogenic determination was studied with seven Corynespora cassiicola strains isolated from main rubber planting area in Yunnan.DF4 was the most pathogenic strain.Resistance of 9 varieties from main rubber planting area in Yunnan was evaluated by inoculating pathogenic strains,inoculating conidial suspension,leaf puncture bioassay and leaf wilt bioassay by utilizing crude toxin.The result showed that evaluation was basically the same with different inoculating methods,but also had certain differences.
