为摸清小麦条锈病在西藏自治区的发生情况,2009～2011年对该区的条锈病进行了调查研究。结果表明,西藏小麦条锈病常年病害发生普遍率稳定在40%左右,但病害的发生受环境条件特别是降水量的影响较大,进一步验证了“西藏小麦条锈病的发生是以本地菌源为主的”这一结论;生理小种鉴定结果表明,西藏与内地优势小种及类群基本一致。但是,西藏地区的菌系具有自身的独特性。 To find out the occurrence of wheat stripe rust in the Tibet Autonomous Region, stripe rust in this area was investigated from 2009 to 2011. The results showed that the prevalence of annual incidence of stripe rust of wheat in Tibet was stable at about 40%, but the incidence of disease was more affected by environmental conditions, especially precipitation, further verifying that “the occurrence of stripe rust in wheat in Tibet is based on the local bacteria Predominantly ”. The results of physiological races showed that the dominant races and taxa in Tibet are basically the same. However, the strains of bacteria in Tibet have their own uniqueness.
