本文报道了对１９９１～１９９６年采自我国１６个省和自治区的５６０６份小麦条锈菌标样的研究结果，基本反映了这期间我国小麦条锈菌生理小种的变化情况。１９９１～１９９５年，条中２９号出现频率为１３．６％～３２．２％，居于首位，但已呈下降趋势，到１９９６年出现频率仅为５．２％，名列第８；１９９１～１９９２年条中２５号居第２位（３．６％～８．４％）；１９９３～１９９５年新命名的条中３１号（６．６％～１６．７％）和条中３０号（５．７％～７．９％）分别上升为第２和第３位，特别是条中３１号到１９９６年已跃居首位（１３．０％）。条中２１、２２、２３、２６、２８号等小种出现频率均较低，且有逐年下降趋势。１９９４～１９９６年Ｈｙｂｒｉｄ４６和水源１１致病类群的出现频率逐年上升，前者３年分别为１９．６％、３４．８％和３８．２％，后者３年分别为１２．２％、２０．９％和４６．６％。这２个致病类群内分化加剧，到１９９６年已分别分化为９和１２个类型。条锈菌已进入以条中３０号和３１号为代表的Ｈｙｂｒｉｄ４６和水源１１致病类群占优势的新时期。
This paper reports the results of 5606 wheat stripe rust samples collected from 16 provinces and autonomous regions of China from 1991 to 1996, which basically reflect the changes of the race of wheat stripe rust in China during this period. From 1991 to 1995, the frequency of occurrence of Article 29 was 13.6% ~ 32.2% in the first place, but it showed a downward trend. The frequency of occurrence in 1996 was only 5.2% 1992 ranked No. 25 in the second place (3.6% ~ 8.4%); from 1993 to 1995 the newly named Article 31 (6.6% ~ 16.7%) and Article No. 30 ( 5.7% ~ 7.9%) rose to No. 2 and No. 3, respectively. In particular, No. 31 to No. 13 in 1996 ranked first (13.0%). The frequency of races such as 21, 22, 23, 26 and 28 were lower and declined year by year. The frequency of occurrence of Hybrid46 and water source 11 pathogenic groups increased from 1994 to 1996, with the former three years being 19.6%, 34.8% and 38.2% respectively, the latter three years being 12.2% and 20% respectively. 9% and 46.6%. The two pathogenic groups within the group exacerbated by 1996 had been divided into 9 and 12 types. Stripe rust has entered the new era of hybrid46 and water source 11 pathogenic groups represented by the 30th and the 31st of the Article.
