In order to study transmission of 6VS/6AL chromosome through gametes and its genetic stability in different genetic background, the 6VS/6AL translocation line 92R137 (highly resistant to powdery mildew) were respectively crossed to common wheat varieties Bainong 64, Bainong 9310, Han 5310, Xiaoyan 54, Huaimai 20 and Xumai 856 introduced from different areas of China and the hybrids F1 were backcrossed as male and female.

为研究小麦－簇毛麦6VS/6AL易位染色体在不同小麦背景中的遗传稳定性及其在配子中的传递，利用高抗白粉病的普通小麦－簇毛麦6VS/6AL易位系92R137与不抗白粉病的栽培品种百农64、百农9310、邯5310、小偃54、淮麦20、徐麦856进行杂交，并用这些品种分别与杂种Fl进行正反回交。

In this paper,the inheritance and transmission law of the character for wheat leaf-tip necrosis were firstly investigated with the contrasting character of leaf-tip necrosis and normal leaf in wheat varieties for basic test materials by reciprocal crosses and backcrosses,hybrid progeny analysis and aliencytoplasm substitution.

小麦干尖叶是近年在小麦育种中所发现的一种叶部坏死性状，直接影响小麦的产量。

The results implied that two of these three genes, Glb3s2 and Cht4, when transiently expressed in leaf epidermal cells of susceptible wheat variety, can partially inhibit penetration of conidiospores and formation of haustoria, and to some extent increase the resistance of expression cells to powdery mildew.

结果表明，小麦几丁质酶基因Cht4（侵入频率为18.3%，对照为25.04%）和小麦肛1，3葡聚糖苷酶基因Glb3s2（侵入频率为19.63%，对照为24.63%）在感病小麦品种叶片表皮细胞中的瞬间表达，对白粉病菌侵入和吸器形成均有抑制作用，在一定程度上增强了表达细胞对白粉病菌的抗性。

There were significant quality advantages of intercropped wheat compared with sole wheat.

间套作小麦和单作小麦相比具有明显的间套作品质优势，且间作小麦表现出明显的边行品质优势。

With increasing nitrogen application rate, the amount of microbes in wheat rhizosphere increased first and decreased then, with the peak appeared at 180 kg N x hm(-2), and the effect was more obvious on monocropped wheat than on intercropped one.

小麦根际的微生物数量随施氮量的增加先增加后降低，以常规施氮处理(N180)的微生物数量最多，氮肥用量对单作小麦的影响大于间作小麦。

In order to verify the possibility of lyophilization technology used for the drying treatment of wheat seed, different drying modes under lyophilizing, vacuuming and hot air was employed and compared in this research.

为了探索真空冷冻干燥技术用于小麦种子干燥处理的可能性，采用真空冷冻干燥、真空干燥和热风干燥 3种方式对小麦种子进行干燥处理，在不同环境温度和压力下，研究种子中温度-时间分布曲线，并通过分析复水率、出芽率和幼苗生长情况进一步研究了这 3种干燥方法对小麦种子生物活性的影响。

Based on the fluidized bed theory, a series of thin layer wheat drying experiments were carried out in an electric drying oven with gentle breeze in it to simulate the wheat drying process in fluidized bed.

基于流化床干燥理论，采用热风循环充分的电热烘箱作为干燥器，对小麦进行了一系列的薄层干燥实验研究，模拟小麦流态化干燥过程，总结出适用于流化床小麦干燥时间预测的经验回归公式。

A cluster analysis of two-hundred candidate wheat cultivars from Shaanxi, Gansu, Sichuan and Henan provinces recently was performed by using unweighted pair-group average method,based on the data from their seedling resistance reaction to six dominant isolates of Puccinia striiformis with the different virulence.

为了弄清我国小麦条锈病主要流行区后备小麦品种的抗锈性，选用6个条锈菌优势菌系，对陕，甘，川，豫四省近年来培育的200份后备小麦品种进行苗期和成株期鉴定，并分别对不同省份后备品种的抗条锈性进行聚类分析。

For example,disease－resistant varieties of wheat have been crossed with high－yield wheat to combine these Quartz cuvettes .

比如，抗病小麦同高产小麦杂交，形成了一种具有双重特性的新的小麦品种。

The results were as follows:The protein,wet gluten content and sedimentation of all hybrid seeds with 4 alien cytoplasms were superior to those with T.aestivum cytoplasm.The differences of wet gluten content and sedimentation of hybrid seeds with Ae.kotschyi and Ae.variabilis cytoplasms,at 5 percent significant difference,were especially obvious.

结果表明，由它们所配制的杂种小麦在蛋白质含量、湿面筋含量、沉淀值等性状上均高于具有普通小麦细胞质的相同核型杂种小麦，尤其粘、易型某些组合在湿面筋含量、沉淀值两性状上差异达到显著水平。
