摘　　要：研究表明,小麦不孕病在澳大利亚分布虽然比较广泛,但一般发病较轻属于次要病害。34份种子样品检测结果显示,种子阳性带菌率为0～2.2％,平均值小于0.5％。35个田间抽样调查结果,植株阳性症状发病率为0～26.5％,平均值为4％。文章还对不孕病潜在的危险性进行了讨论。The study showed that althrough wheat ringspot pathogen is a widespread fungus, it can generally cause little damage to crops in Australia due to its low infection rates. Positive ringspot infection rates detected from 34 seed samples are ranged at 0-2.2% with an average of less that 0.5% . Positive incidences of ringspot in 35 field samples are ranged at 0-26.5% with an average of 4% . The pathogenic potential risk is also discussed here.
