Two chromosome translocation lines were screened for wheat breeding program to control BYDV.

本研究采用RAPD方法，对具2Ai-2端体和完整染色体异附加或异代换系进行分析，从随机引物中，选出两个分别位于2Ai-2染色体两臂上的分子标记，然后用这两个标记对中间偃麦草和普通小麦的杂交后代进行筛选，选出小麦抗黄矮病易位系新材料。

The relative efficiency of pre-selection of young bulls before progeny-testing with marker-assisted BLUP over conventional progeny-testing(i.e.random selection before progeny-testing)for five generations was studied using Monte Carlo simulation.

在主基因-多基因混合遗传模型的框架内模拟研究了种畜遗传评定的相对效率，比较了常规BLUP与标记辅助BLUP进行个体遗传评定的效果，模型中将与标记紧密连锁的QTL效应看作随机效应。

For instance ,the later generations of Watt could invent the steam engine car just because of the contribution of his steam engine ;the coming into being of flattop is mainly contributable to the first plane of Wright brothers ;after the discovery of electricity ,the lamp ,the electromotor and electrocar come out one after another .

In order to clarify the rules of POD isoenzyme in the hazelnut, identify their blood relations between female, male and filial generations and select the superior parents for cross-breeding, we have studied the characteristics of peroxidase isoenzyme which are distributed in the 34 hazelnut varieties or lines by polyarclamide gel electrophoresis, The results showed that:POD isoenzymes of Corylus heterophylla Fisch, Corylus avellana L, and the hybrid of Corylus heterophylla Fisch × Corylus avellana L had obvious difference; some hybrids had lost P10 spectrum band of parents; the enzyme spectrum of 32 hybrid hazelnuts produced 'new hybrid spectrum bands'that could be considered as a mean to identify hybrids.

为了阐明过氧化物同工酶在榛品种中的分布规律，探讨平榛、欧榛及其杂种榛之间的亲缘关系，选育优势杂交亲本，本试验采用聚丙烯酰胺凝胶垂直电泳，研究了34个榛品种成熟叶过氧化物酶同工酶酶谱特征，结果表明：平榛、欧榛及其平欧杂种榛品种间酶谱具有较大差异；有的杂种品种遗失了父母本共有谱带P10；32个平欧杂种榛品种出现了双亲所不具有的新酶带，可作为鉴别杂种的一条途径。

They still possessed the earth on sufferance: since the Morlocks, subterranean for innumerable generations, had come at last to find the daylit surface intolerable.

In telling the vibrant story of The Poincaré Conjecture, Donal O'Shea makes accessible to general readers for the first time the meaning of the conjecture, and brings alive the field of mathematics and the achievements of generations of mathematicians whose work have led to Perelman's proof of this famous conjecture.

Donal O'Shea 通过告诉读者 Poincaré猜想这个振奋人心的故事，让第一次接触到这个领域的大众读者们能够更容易的理解其意义，使数学领域更为形象化，以及赞扬了从古至今历代的数学家们，正是他们为数学做出的杰出贡献才使得Perelman的有关数据更具有了说服力。

Here I would essentialize t he systems thinking of Chinese three generations leadership for grasping the civilization evolution in worldization times to the Western friends by systems approach, and simply explain the so-called "Three Represents" thought that has delivered formally by Chinese leadership at the 16th National Congress of the Communist Party of China few days ago.
