Presently, the better methods against the wheat stripe rust are using resistance cultivars and chemicals.

中国是世界上最大的小麦条锈病流行区，小麦条锈菌流行体系是一个相对独立的体系。

Wheat stripe rust (Puccinia striiformis f.sp.tritici) is one of the most destructive diseases to wheat in China .

小麦条锈病(Puccinia striiformis f.sp.tritici)一直是我国小麦的主要病害，成灾频率高、流行范围广。

F.sp. tritici can offer consult and help for wheat rust study about variation and evolution.

本研究获得的有关小麦条锈菌群体毒性变异和小种的信息，可以为未来研究小麦条锈菌的毒性变异和群体进化及监测提供一些参考和帮助。

Wheat stripe rust, caused by Puccinia striiformis f.sp. tritici West., is one of the most important wheat diseases in the world, especially in China.

小麦条锈病是一种世界性病害，中国是世界上最大的小麦条锈病流行区，条锈菌又是一个相对独立的流行区系。

The problem that in introducing Japan to produce wheaten characteristic, wheaten production, exists and corresponding countermeasure.

介绍日本产小麦的特点、小麦生产中存在的问题和相应的对策。

Different stages and different degrees of high temperature stress experiments were done to study the response of yeild and quality formation of wheat cultivars with different heat tolerance to high temperature stress.

对不同耐热性的小麦品种进行不同时期和不同强度的高温处理，研究了不同耐热性小麦品种产量和品质的形成对高温胁迫的响应。

The effects of environment factors on the black point rate, yield and quality of spring wheat have certain correlations.

小麦抽穗至成熟期间低温、多雨的环境条件有利于小麦黑胚病的发生，也有利于产量的提高，但这种环境条件不利于优良品质的形成。

The single micronucleus and multi-micronucleus were observed at the interphase. The chromosome aberrational cells including chromosome fragment, lagging chromosome, chromosome bridge and circular chromosome were found during the mitosis. RAPD analysis of seedling genomic DNA variation in M 2 generation of three mutants showed their DNA sequences had changed. The result confirmed that the implantation of 7Li +3 ions could induce genetic mutation in wheat.

对幼苗根尖细胞学研究观察，获得单桥、双桥、桥断裂、落后染色体、三级、断片和微核等畸变类型；对已获得的小麦突变株，分别进行M2 代DNA分子的RAPD分析，结果发现DNA均发生变异，证明7Li+ 3 注入通过内靶核反应能够诱发小麦在分子水平上产生遗传变异。

The experiments were conducted with seed soaked and wheat sprayed with RAD that is a resistance agricultural chemistry pharmaceutical preparations to study effect of RAD on agronomical character and yield and quantity of wheat.

本实验用RAD对小麦进行浸种和喷施，研究RAD对小麦农艺性状和产质量的影响。

The phylogenetic analysis based on the sequences in this region indicated that the y-type HMW glutenin subunits of Agropyron elongatum species were different from other subunits, whereas the x-type subunits of them were most closely related to that from the B genome.

推测四倍体长穗偃麦草中的E1基因组可能起源于二倍体的E基因组。与来自小麦族的A、B、D和G基因组部分亚基基因的启动子序列比较表明，小麦族的这一区域在进化上是相当保守的，不同基因组来源的序列同源性都在90%以上。
