1997~ 2 0 0 1年采自我国 13个省和自治区的主要生产品种和重要抗源上的小麦条锈菌标样 4 0 0 8份 ,其鉴定结果基本反映了这期间我国小麦条锈菌生理小种的变化状况。 1997年发现了水源 11致病类型 13和 14 ,2 0 0 1年把原Hybrid 4 6致病类型 3(HY 3)命名为条中 32号。这期间共监测到 4 1个小种和致病类型 ,每年都能监测到的小种和致病类型有 32个 ,为条中 17、19、2 1、2 2、2 3、2 5、2 6、2 8号 ,洛 10 2 ,条中 2 9,洛 13 2、3,条中 30、31、32 ,Hybrid 4 6 4、5、6、7、8,水源 11 2、3、4、5、6、7、8、10、11、12、13和 14。条中2 9、30、31、32号为主要流行小种。 1997~ 2 0 0 0年间条中 31号位居第一 ,出现频率为 10 .8%~ 13.5 % ,其次为条中 32号 (4 .8%~11.7% ) ,由于条中 32号逐年持续上升 ,2 0 0 1年超过条中 31号而位居第一。其次是条中 2 9和 30号 ,两者出现频率基本相当 ,1997~ 1999年条中 2 9号略高位第 3(3.3%~ 4 .0 % ) ,条中 30号位第 4 (2 .6 %~ 3.3% ) ,2 0 0 0~ 2 0 0 1年 ,条中 30号略高位第 3(3.6 %~7.3% ) ,条中 2 9号位第 4 (2 .7%~ 3.1% )。出现频率较高的还有条中 2 3号、2 5号、2 6号、2 8号和Hybrid 4 6 4、5、7、8,水源 11 3、4、5、7、11、13和 14 ,其它为?
During the period from 1997 to 2001, 380 samples of wheat stripe rust were collected from the main production varieties and important sources of resistance in 13 provinces and autonomous regions of our country. The identification results basically reflected that during the period, Physiological race changes. In 1997, water sources 11 and 13 were identified. In 2001, the original Hybrid 4 6 disease type 3 (HY 3) was named No.32. During this period, a total of 41 races and pathogenic types were detected. There were 32 races and pathogenic types that could be detected each year. The average number of races and pathogenic types was 17,19,2 1,2 2,2 3,2 5, 2 6,2 8, Los 10 2, Article 2 9, Los 13,3, Article 30,31,32, Hybrid 4 6 4,5,6,7,8, Water 11 2,3,4 5, 6, 7, 8, 10, 11, 12, 13 and 14. Article 2 9,30,31,32 as the main epidemic race. From 1997 to 2000, No. 31 ranked the first with frequency of 10.8% -13.5%, followed by No. 32 (4.8% -11.7%) of the Article. Since No. 32 of the Article continued year after year Rose in 2001, surpassing No. 31 in the first place. Followed by Article 29 and 30, the frequency of occurrence of the two basically the same, 1997-1999 article 29 slightly higher third (3.3% ~ 4.0%), the 30th of Article No. 4 (2. 6% ~ 3.3%). From 2000 to 2001, the number 3 slightly increased from 3% (3.6% -7.3%) in Article 30, the fourth (2.7% -3.1% ). The more frequent occurrences are the number 2 3, number 2 5, number 2 6, number 2 8 and Hybrid 4 6 4,5,7,8, water sources 11 3,4,5,7,11,13 and 14, the other is?
