On the basis of determining their resistant spectrum, CY21, CY23, CY27, CY29, CY30, CY31, CY32, Su-11, Su-14 were used to investigate the resistant components at seeding stage, such as latent period, infection efficiency, uredinium length, sporulation capacity, period of spore production and severity. Also, two equal weight races' mixture CY27:CY30, CY27:CY31, CY27:CY32, CY31:Su-4, CY30:Su-11 were continued to reproduce six generations of Libellula and Xiannong 4 respectively, and the ration changes of each race were tested.

在抗性谱测定的基础上，采用CY21、CY23、CY27、CY29、CY30、CY31、CY32、Su-11、Su-14等9个条锈菌菌系，分别测定其苗期潜育期、侵染频率、夏孢子堆长度、产孢强度、产孢期以及严重度，同时将CY27：CY30、CY27：CY31、CY27：CY32、CY31：Su-4、CY30：Su-11等5个等量混合菌系组合分别在里勃留拉和咸农4号上继代培养6代，测定各小种在组合中的比例变化。

This was followed by the Libellula II which used a higher powered 105hp Walter Minor 4-III engine and had an enclosed cockpit.

其次是由二里勃留拉的采用高功率105hp沃尔特小调4 - III引擎，并已封闭的座舱。

Libellula was immune to stripe rust in 2000 and infected by the disease in other years, but its disease index was only 0.01%-5%.

斯特拉姆潘列在近30年间表现了突出的持久抗性。里勃留拉一年表现免疫，其余年份均发病，但病情指数仅为

Libellula and Xiannong 4 had different certain seeding resistances to rust, and Xiannong 4 could converge more races than Libellula.

里勃留拉和咸农4号均具有不同程度的苗期抗病性，咸农4号对小种的聚合作用大于里勃留拉。

Libellula and Xiannong 4 are classic durable resistant varieties in Southern Region of Gansu Province where wheat stripe rust is serious. The study was done in order to reveal their seeding resistant characteristics and mechanism.

The Libellula was the brainchild of Count Ettore Manzolini.

该里勃留拉是曼佐利尼伯爵埃托雷心血结晶。

Researches for 32 years (1973-2004) conducted in Longnan, one region in China where wheat stripe-rust strain is labile, have shown that most wheat cultivars lost their resistance to stripe rust after 3-8 years, while Libellula and N.

在我国小麦条锈病常发易变区陇南地区，从1973年起对里勃留拉、N。斯特拉姆潘列、成农4号、清农1号、中梁5号和清农3号6个品种抗杀锈病的持久性进行了鉴定与分析。

Libellula had different resistance to different races and Xiannong 4 was susceptible to all the races except CY18 and CY22. Resistant components had significant variances among different cultivars, races and cultivar×race. And Libellula had strong selection on different races, while the selection of Xiannong 4 was weaker than that of Libellula.

里勃留拉的抗性谱较宽，抗病性在小种间差异明显，而咸农4号对除CY18、CY22外的小种均感病；两者的抗病性组分在品种间、小种间以及品种×小种互作时均有显著差异；里勃留拉对不同菌系有较强的选择作用，而咸农4号的选择作用较弱。
