Among collections chiefly from North China,different races of Pucciniaglumarum were identified by means of differential hosts used by Gassner & Straibor a set of improved varieties of wheat grown in China. Among 14 improved varieties,marked differences in resistance to stripe rustwere observed.Li-Yung I was resistant to 40 out of 50 collections of striperust,with unstable reactions to 7 collections; Nanking 4197 was resistant to 37 ??collections with unstable reactions to 9 collections; while Yechao 35368 and Ye-Ta 1885 were susceptible to all except 5 collections from FJymus ckinense.Theinstability of varietal reactions is one of the principal obstacles in identification.As a consequence,tests with 6 improved varieties including Early Premium,Pi-Ma 1,etc.,only 21 out of 50 stripe rust collections could be differentiated into10 distinctly different races (Y 1 to Y10).However,there were great differencesin pathogenicity among different races so far identified.All the 6 improvedvarieties were resistant to race Y 1 and susceptible to race Y 2.The virulenceof other races differed from one another also pronouncedly. Races Y2,Y3,Y4,Y5 ,Y6,Y7 ,and Y8 were collected from wheat; Y 9 andY10 from Agropyron spp.; and Y1 was collected mainly from Elymus chinense(including 1 collection from wheat).Races Y 1,Y 3.Y 4,Y 5,Y 7,Y 8,Y 9,Y 10were found in Hopeh; Y 1,Y 2,Y 6,Y 7 in Shansi; and Y 6 in Shantung. All collections could be readily grouped into 16 different forms if the highestreaction type was taken as a basis for identification (this method of groupingwas adopted by Fang et al).Comparing the results with that of Fang et al,itappeared that reactions of certain varieties,such as Early Premium,Li-Yung 1 tocollections from North China were distinctly different from their reactions tocollections from East China.This suggested strongly that races of stripe rustorganism between these two regions might be quite different. All wheat varieties tested were found to be resistant to stripe rust collectionsfrom Elymus chinense.whereas collections from Elymus sibiricus and Agropyronspp.were capable of attacking many wheat varieties. Single spore infection of stripe rust frequently resulted in sporulation on thewhole leaf blade.This is definitely much more systemic than infections of eitherstem rust or leaf rust organism.Inoculations with single uredospores and mono-uredospore lines often produced mixtures of infection types ranging from resistantto susceptible on same leaf blades.This is analogous to "X" type reactions re-ported in stem rust and leaf rust literature; therefore,"X" type reaction shouldalso be recognized in the study of stripe rust.

1950年以来自华北以及少数其他地区搜集的条銹菌种,不論在Gassner和Straib所用的鑒定寄主或在国內推广品种上鑒定,都可区分出許多不同的类型。所用14个推广品种对于这些条绣菌种的抗病性有着很大的差別;其中以驪英1号最抗病,对50个菌种中的40个菌种是抵抗的,对7个菌种反应不稳定;金大4197次之,对37个菌种是抵抗的,9个菌种反映不稳定;燕交35368及燕大1885除了对5个碱草(Elymus chin-ense)条銹菌种抵抗外,对其他所有菌种的反应都是感染型。品种反应的不稳定,是鑒定工作中的主要困难。加根据早洋麦、农大3号、碧螞1号、碧螞4号、驪英3号、玉皮麦等6个品种的稳定反应加以分析,仅能將50个菌种中的21个区分成10个显著不同的类型。这6个品种对第一类型均为抵抗,对第二类型均为感染,其他类型的致病力介于二者之間。在这10个类型中,类型Y_2,Y_3,Y_4,Y_5,Y_6,Y_7,Y_8采自小麦;类型Y_9,Y_(10)采自Agropyron spp.;类型Y_1主要采自Elymuschinense(包括一个小麦菌种)。河北出現的类型有Y_1,Y_3,Y_4,Y_5,Y_7,Y_8,Y_9,...

1950年以来自华北以及少数其他地区搜集的条銹菌种,不論在Gassner和Straib所用的鑒定寄主或在国內推广品种上鑒定,都可区分出許多不同的类型。所用14个推广品种对于这些条绣菌种的抗病性有着很大的差別;其中以驪英1号最抗病,对50个菌种中的40个菌种是抵抗的,对7个菌种反应不稳定;金大4197次之,对37个菌种是抵抗的,9个菌种反映不稳定;燕交35368及燕大1885除了对5个碱草(Elymus chin-ense)条銹菌种抵抗外,对其他所有菌种的反应都是感染型。品种反应的不稳定,是鑒定工作中的主要困难。加根据早洋麦、农大3号、碧螞1号、碧螞4号、驪英3号、玉皮麦等6个品种的稳定反应加以分析,仅能將50个菌种中的21个区分成10个显著不同的类型。这6个品种对第一类型均为抵抗,对第二类型均为感染,其他类型的致病力介于二者之間。在这10个类型中,类型Y_2,Y_3,Y_4,Y_5,Y_6,Y_7,Y_8采自小麦;类型Y_9,Y_(10)采自Agropyron spp.;类型Y_1主要采自Elymuschinense(包括一个小麦菌种)。河北出現的类型有Y_1,Y_3,Y_4,Y_5,Y_7,Y_8,Y_9,Y_(10);山西出現有类型Y_1,Y_2,Y_6,Y_7;山东出現有类型Y_6。品种不稳定反应除通过选擇反应較为稳定的品种来克服外,同时还須严格掌握温室条件。如以品种的最高反应为标准(如方中达、陈迺用所采用),則可將上面50个菌种分成16个不同的类型。与华东的結果比較,許多品种如早洋麦、驪英1号等对兩个地区条銹病菌的反应适相反,表明华东和华北条锈菌的致病力可能有很大的差別。Elymus chinense的条銹菌与小麦条绣菌的致病力有極大差异,所测定的小麦品种对前者均抵抗。Elymus sibiricus和Agropyron spp.的条绣菌則能正常侵染多种小麦品种的幼苗。条銹菌在小麦叶片內能适当的扩展,較秆銹菌和叶銹菌更有系統性,單孢子接种約在二星期左右可蔓延到整个叶片。同一叶片上常出現抗病和感病的反应,用單孢及單孢菌系接种,得出同样結果。条绣菌的鑒定标准中除了原有的反应型外,还应加入混合型“X”一項。

Seventeen thousand six hundred and twenty one common wheats, 801 rare species of 20 races, 25 species of 3 related genera, and 118 Triticals were systematically studied for their resistance to scab (Gibberella zeae) by the artificial inoculation under the moisture-maintaining conditions in the fields. Three hundred eighty five varieties with resistant and moderately resistance were selected. Repeated tests showed that there are a sort of wheat varieties with high and stable resistance among the wheat germplasm resources, which were not reported in the early research work on wheat resistance to scab. So far, these varieties have still been the most excellent scab-resistant sources, in addition, moderately resistant and susceptible varieties may also be utilized as resistance sources.The scab-resistant resources of wheat germplasm were mainly distributed to the scab epidemic regions in the world. The middle and lower reaches of the Yangtse River which is one of the regions where scab occurs frequently, is abundant in resources of the resistance to scab. Among the tested rare species, most of them were susceptible, and a few were moderately susceptible, and none of resistant and moderately resistant varieties was discovered. Of the tested related plants, a species of Secale showed moderately resistant.

作者在田间人工接菌和加湿的条件下,系统研究了17,621个普通小麦品种(系)、20个种族的801个稀有种(品种)、三个属的25个近缘植物材料,以及118个小黑麦对赤霉病(Gibberella zeae)的抗性,筛选出385个抗和中抗品种。经多年反复测定证明:小麦品种资源中存在一类早期研究没有报道过的抗性强而稳定的品种,它们是目前世界上最优良的抗源;中度抗病及中度感病的品种亦可作为抗病育种的抗源;抗赤霉病的小麦品种资源主要分布于世界上赤霉病流行区。由于长江中下游是世界上赤霉病流行最频繁的地区之一,因而抗赤霉病的小麦品种资源亦极为丰富;供试的小麦稀有种,大多是感赤霉病的,少数是中度感病的,没有发现抗或中抗的种(品种);供鉴定的近缘植物材料中有一个黑麦属材料是中度抗病的。抗赤霉病性(以下简称抗赤性)与株高没有固定的联系,但与颖壳颜色、腊质层、叶色、小穗排列稀密度、毛茸以及开花习性等特征特性有一定的联系。
