杂种的

Since microspore mother cells showabortion during the first meiotic divison,it is suggested thatthe early male abortion is frequently associated with variousdegrees of impairment to the fertility to the female〓amate.

研究的27个杂种第一代中，有11个组合的产量超过对照或与对照持平，占总组合数的40.74%。在强优势组合中，不育细胞质带来的负效应不足以使F1产量的显著降低，而且通过杂优补偿作用可比对照有所提高。

Its contents are as follow: A description for the characteristics of Agropyron elongatum and its genome; the methods used to overcome the cross-sterility and hybrid sterility; the cross breeding procedure and the genetic analysis for it; the selected hybrids which are the Triticum-Agropyron octoploid species, the alien addition lines, the alien substitution lin...

内容介绍了长穗偃麦草的特性和染色体组型，克服杂交不育和杂种不育的方法，杂交育种的程序及其遗传分析和选出的小偃麦八倍体种、异附加系、异代换系与丰产抗病的小偃麦新品种。

Everybody believe it to be odious and abominable because everybody says so: and so the dog, and most deservedly, gets a bad name, but he is not hanged; he is simple avoided. Because he is such a mangy, ill-looking cur, offensive alike to the nose and to the touch, all decent people shrink away from him.

每个人都认为它是令人作呕的以及罪大恶极的，因为他们这么说：就像狗一样，其理所当然地应该获得一个恶名，但是其却没有被吊死；他活了下来，因为他是如此污秽不堪，病态的杂种，令人避之不及，所有体面的人都会离他远远的。

John's mother, Eleanor , takes a liking to the Bastard, because it is rumored that his father was her son and John's brother, Richard the Lionhearted.

约翰的母亲埃莉诺，需要喜欢的杂种，因为这是传言，他的父亲是她的儿子和约翰的弟弟，理查德

Using the method of single factor variance,the SSR markers correlated with wood density,fibre length,fibre width and fibre angle were identified to be 5,7,4 and 2,respectively.

结果表明：纤维长有明显的杂种优势，控制该性状表现的基因之间具有正效应的互作；控制木材基本密度的基因之间具有负效应的互作。

The near isogenic lines containing the S5n allele from different original WCVs . and genetic background from japonica variety Balilla were crossed with 20 indica-japonica varieties representing different ecotypes, the results indicated that genetic effect of S5n from different wide compatibility varieties was not completely same, and that the compatibility power and compatibility spectrum of near isogenic lines carrying S5n from different donors were different.

以不同来源的广亲和品种为供体、以粳稻品种Balilla为受体的近等基因系与不同籼粳测验种测交结果表明，不同起源的广亲和基因S_5~n对杂种育性的遗传效应是不完全相同的，亲和力和亲和谱都存在差异。

Study on the genetic characteristic of improved lines which can broad temperate maize genetic basis, found new heterotic patterns, resolve the back and force situation, overcome the obstacle of high and super- high yield breeding, provide the technique guarantee for the sustainable development of Chinese maize production.

对改良系进行遗传研究，拓宽温带玉米的遗传基础，构建新的杂种优势模式，这将解决我国玉米育种徘徊不前的局面，克服玉米高产超高产育种的障碍，为我国玉米生产的可持续发展提供技术保障。

Crosses of the 13(15) crosses with higher protein content in kernel composed by parents from different heterotic groups, so the inbreds with high protein content and high combining ability from different heterotic groups was the genetic basis for making high protein crosses.

在子粒粗蛋白质含量相对较高的13(15)个组合中，92.3%(80%)组合的双亲来源于不同的杂优类群；因此，来自不同杂种优势类群的高蛋白、高配合力自交系是组配蛋白质含量较高组合的基础。

Accordingly we start from the definition of heterosisH=F1-MP,where H is heterosis, F1 is the first generation offspring, MP is the mean of the parents or midparent, and from the use of a binomial random variable and its extention to the multinomial case derive the basic relations of heterosis with its components.

另一在原文中未加说明的原因是，用配合力概念需要无穷多个品系才能和遗传力的结果相比较，仅此一点就把配合力的作用排斥掉了。文中的主题是杂种优势老大难题可以用笛卡尔的推理方法来解决。

Fal.But, as ill luck would have it, three mi**egotten knaves,in Kendal green,came at my back,and let drive at me;—for it was so dark, Hal, that thou couldst not see thy hand.

福斯塔夫可是偏偏魔鬼跟我捣蛋，三个穿草绿色衣服的杂种从我的背后跑了过来，向我举刀猛刺；那时候天是这样的黑，哈尔，简直瞧不见你自己的手。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
