Rice blast is one of the major diseases of rice in China.Since the 1960's it has frequently been found that some resistant cultivars gra- dually lost their resistance to this disease during the course of their cultivation. During the last four years,the screening of the differential varie- ties for the identification of the races from 212 rice varieties grown in the various parts of the country has been carried out by using 1739 monoconidial isolates of the samples collected from 21 provinces and autonomous regions.Seven varieties,Tetep,Zhenlong 13,Sifeng43, Dongnong 363,Kanto 51,Hejiang 18,Ligiang-sintuanheigu were em- ployed as the differential varieties in China.Meanwhile,828 isolates from monoconidial cultures collected from 23 provinces and autonomous re- gions were identified on the Chinese differential varieties.The results pointed out that the isolates can be divided into 7 groups with 43 ra- ces,among which,race Zhong Gl is widely distributed and appears in high frequency,indicating that it is the dominant race in this country. The composition of the races in indica rice growing areas and japonica -indica rice mixing growing regions in South China is much complicated than that in japonica rice growing region in North China.It seems that the indica races (with S reaction on indica differentials) in the South is much virulent than that in the North. Preliminary research shows that the main cause for the loss of resis- tance in a variety is the appearance of new virulent races.Unfavoura- ble environment and improper cultivation are not factors to be ignored that speed up the loss of resistance in the variety. The variability of isolates of P.oryzae was also studied with the different monoconidial cultures originating from the same disease lesion and the cultures derived from single cells of conidiospore.The patho- genicity of the isolates either cultured for several generations or from reisolation of the original isolates from the fresh disease lesions was also tested.The results indicated that although some changes in pathogenicity were observed,most such isolates showed relative stability. In the same time,after repeated trials,some comparatively stable iso- lates have been selected for the basis of further studies on the genetic analysis of disease resistance.

稻瘟病是我国水稻主要病害之一,六十年代以来,在生产上不断发现一些抗稻瘟病的品种,但在推广、栽种的过程中逐渐丧失了抗病性。为探明其丧失原因及防治对策,1976年起开展了全国稻瘟病菌生理小种的协作研究。四年来,先后用21个省、市、区的1739个单孢分离物对212个水稻品种进行了筛选测定,从中选出特特勃、珍龙13、四丰43、东农363、关东51号、合江18号和丽江新团黑谷7个品种为中国稻瘟病菌生理小种的鉴别品种,并从23个省、市、区提供的827个单孢分离物中鉴定出7群43个中国小种,其中以“ZG_1”小种分布最广,出现频率最高,是我国的优势小种。南方籼稻区和籼、粳稻混栽区的小种组成较北方粳稻区复杂,而籼型小种(在籼稻鉴别品种上为 S 反应的小种),主要分布在南方稻区。初步研究表明品种抗病性的丧失,主要是由于出现了能侵染该品种的新小种所致。不良的环境条件和栽培措施也是加速品种抗性丧失的一个不可忽视的因素。通过对同一病标样上分离的各单孢培养菌,同一单孢不同细胞发育而成的培养菌、同一分离物转管代次及单孢分离物接种后再分离菌的致病性变异观察,初步看到稻瘟病菌致病性虽有变异的情况,但多数情况是稳定的。同时,通过反...

27 isolates belonging to 4 Chinese races of blast fungus,which wereisolated from japonica varieties in North China,were divided into 11races by using 9 Japanese differential varieties with single resistancegene in 1982.42 isolates,classified into 7 Chinese races,were determ-ined by 12 Kiyosawa's differential varieties in 1983.The result indicatedthat 19 Japanese races were included in 42 isolates.It can be concludedthat kiyosawa's differential varieties and Japanese ones have higher abi-lity differentiating...

27 isolates belonging to 4 Chinese races of blast fungus,which wereisolated from japonica varieties in North China,were divided into 11races by using 9 Japanese differential varieties with single resistancegene in 1982.42 isolates,classified into 7 Chinese races,were determ-ined by 12 Kiyosawa's differential varieties in 1983.The result indicatedthat 19 Japanese races were included in 42 isolates.It can be concludedthat kiyosawa's differential varieties and Japanese ones have higher abi-lity differentiating pathogenic races.Three sets of presumable differential varieties,any one of whichconsists of 7 varieties selecting at random from Kiyosawa's differentialvarieties,were used to test 42 isolates.Former two sets can be divided 42isolates into 13 races respectively and later set into 9 races.Fromthese results,it can be concluded that differential variety with singleresistance gene has highest ability differentiating pathogenic races of blastfungus.Kiyosawa's differential varieties can be used to study races in ricecropping regions of North China before ideal Chinese differential varie-ties are determined.It can provide useful information for distributionof resistant varieties with known resistance genes.

1982年,利用日本9个单基因的鉴别品种,把我国北方粳稻品种上分离的27个稻瘟病菌株(分属于4个中国小种)划分为11个小种。1983年,用清泽的12个鉴别品种测定了分属于7个中国小种的42个菌株。结果表明,42个分离菌中包括了19个日本小种。由此可以断定,日本鉴别品种和清泽鉴别品种具有比较高的鉴别生理小种的能力。利用由清泽鉴别品种任意选出的7个品种组成一套假设的鉴别品种,用三套假设的鉴别品种测定42个分离菌。前两套假设鉴别品种分别把42个菌株分为13个小种,后一套(?)品种划分42个菌株为9个小种。由这些结果可以断定,单基因的鉴别品种具有最高的小种鉴别能力。在理想的中国鉴别品种确立之前,可以利用清泽鉴别品种来研究我国北方稻作区的小种。它能为具已知抗病基因的抗病品种的布局提供有用的情报。

The present study on 17 rice cultivars,which were cultivated in Northern China from early of this century to today,indicated that:1).The characters of cultivars had been changed obviously in the successionof rice,showing a tendancy from big-ear and tall-stalk to multiple-earsand short-stalk.2).The general trend of nitrogen response of cultivars varied towards the cultivars suitable for higher level of nitrogen fertilizer.In reverse,the nitrate reductase activity of cultivars variedtowards lower level,resulting...

The present study on 17 rice cultivars,which were cultivated in Northern China from early of this century to today,indicated that:1).The characters of cultivars had been changed obviously in the successionof rice,showing a tendancy from big-ear and tall-stalk to multiple-earsand short-stalk.2).The general trend of nitrogen response of cultivars varied towards the cultivars suitable for higher level of nitrogen fertilizer.In reverse,the nitrate reductase activity of cultivars variedtowards lower level,resulting in a close relation with nitrogen response.In general,the cultivars in early period exhibited a big ear and tallstalk,higher nitrate reductase activity,sensitive to lodging and suitablefor lower level of nitrogen fertilizer.The cultivars in late period exhibited multiple ears and a short stalk,lower nitrate reductase activity,resistant to lodging and suitable for higher level of nitrogen fertilizer.The further analysis revealed a significant negative correlation of nitrate reductase activity with the ears/m~2 of cultivar(r=-0.7302~*)and asignificant positive correlation of nitrate reductase activity with theheight of stalk of cultivar(r=+0.6815~*).

北方粳稻栽培品种演变过程中品种性状和硝酸还原酶活力变化的研究表明:1)品种性状在演变过程中有了明显的变化,即从大穗高秆向多穗矮秆的方向变化;2)品种抗倒耐肥性变化的总趋势是由弱到强,其硝酸还原酶活力从高到低的变化。这就是说过去老品种大穗高秆,不抗倒不耐肥,硝酸还原酶活力高,而目前推广品种多穗矮秆,抗倒耐肥,硝酸还原酶活力低。对硝酸还原酶活力与品种性状之间的相关分析进一步指出,品种间单位面积有效穗数与硝酸还原酶活力呈显著的负相关;品种间株高与硝酸还原酶活力呈显著的正相关。
