１９９１～１９９４年对条锈菌生理小种演变情况进行监测研究结果表明，条中２９号仍是山东省当前优势毒性小种，其对多数生产品种具有较强毒力，对鲁麦１６、鲁麦１９及多数新品系和抗源则无毒性或弱致病性；近年出现的条中３０号新小种，其毒性基因谱更宽，应加强对其监测和流行预测。本文还介绍了１９６３～１９９０年山东省小麦条锈菌在不同时期优势小种的演变及其与小麦品种抗性丧失的关系。 From 1991 to 1994, the evolution of stripe rust races was monitored. The results showed that No.29 was still the current dominant races in Shandong Province, which showed strong virulence to most cultivars. Wheat 19 and most of the new lines and anti-source are non-toxic or weak pathogenicity; in recent years, the new race 30, the narrower spectrum of the gene spectrum of toxicity, should strengthen its monitoring and epidemic prediction. The article also introduced the evolution of the dominant races of wheat stripe rust in Shandong Province from 1963 to 1990 and their relationship with the resistance loss of wheat cultivars.
