对1996年甘肃省205份小麦条锈菌标样进行了鉴定分析,共监测出34个小种类型。其中,能够明确归类的有24个,共计165份,占监测样的80.5%;感染水源11、Hybrid46暂无法归类的10个,共40份,占19.5%。发现水源11和Hybrid46两致病类群持续上升,已由1995年的75.4%上升到1996年的85.9%。条中31号仍为第1位流行小种,Hybrid46类型8和水源11类型3、类型2、类型9已跃居为第2、3位优势小种,条中29号则降为第6位,老小种基本保持稳定。监测结果表明,甘肃小麦条锈菌仍处于强烈分化阶段,条锈菌31号小种及水源类型将是威胁小麦生产的主要致病类型。
In 1996, 205 samples of wheat stripe rust in Gansu province were identified and analyzed, and 34 minor species were detected. Among them, 24 can be clearly classified, a total of 165, accounting for 80.5% of the sample; infection 11, Hybrid46 temporarily uncategorized 10, a total of 40, accounting for 19.5%. It was found that the two pathogenic groups, Water 11 and Hybrid 46, continued to rise, rising from 75.4% in 1995 to 85.9% in 1996. No. 31 is still the first races of race No. 31, Hybrid46 type 8 and Type 11 of water source 3, Type 2, Type 9 have leapt to No. 2 and No. 3 races, while No. 29 of No. 29 has been reduced to No. 6 The old breed basically remained stable. The monitoring results showed that the stripe rust of wheat in Gansu is still in a stage of strong differentiation. Stripe rust race 31 and water source type will be the main pathogenic types that threaten wheat production.
