稻瘟病菌研究是探索稻瘟病发生规律和确定防治策略的基础性工作。本试验利用中国统一的7个稻瘟病菌鉴别品种,对2013年在山东省4个地点采集的菌株进行了生理小种鉴定。结果表明:4个地点共分离出26个单孢菌株,分属4群5个生理小种,其中优势种群为ZF群,该种群出现频率为73.8%;优势小种为ZF1,其所占比例为73.8%,在采样的4个地点均有出现。表明目前山东稻区稻瘟病菌主要以粳型小种为主,并有向籼型小种演变的趋势。
稻瘟病菌研究是探索稻瘟病髮生規律和確定防治策略的基礎性工作。本試驗利用中國統一的7箇稻瘟病菌鑒彆品種,對2013年在山東省4箇地點採集的菌株進行瞭生理小種鑒定。結果錶明:4箇地點共分離齣26箇單孢菌株,分屬4群5箇生理小種,其中優勢種群為ZF群,該種群齣現頻率為73.8%;優勢小種為ZF1,其所佔比例為73.8%,在採樣的4箇地點均有齣現。錶明目前山東稻區稻瘟病菌主要以粳型小種為主,併有嚮秈型小種縯變的趨勢。

The research of Magnaporthe grisea is the base of exploring occurrence rules and determining control strategies of rice blast.Some strains were collected from four regions of Shandong Province in 2013, and their physiologic races were identified using 7 standard rice blast fungi commonly used in China.The re-sults showed that 26 monospore isolates were obtained from the four regions, which belonged to 5 physiological races, 4 groups.Among them, ZF group was the most prevalent one with the highest occurrence frequency of 73.8%;and ZF1 was the predominant physiologic race with the occurrence frequency of 73.8%, which could be found in all the four regions.In conclusion, Japonica race was the main type in Shandong rice production areas now, but it had the evolution trend to Indica race.
