Firstly, cross donor and recipient lines to produce F1; secondly, repeated backcross the F1 individuals and the subsequent progenies with the recipient to recover its genetic background; and thirdly, intercross the backcrossed progenies to fix the introgressed genes in the population.

在标记辅助导入过程中，标记信息既可用于辅助前景选择，即对目标基因携带者的选择，以保证目标基因的正确导入，也可用于辅助背景选择，即对受体基因组的选择，以加快受体遗传背景的恢复。

In this study we mapped a grain length controlling gene named Lk-4 with SSR and CAPs markers by screening 800 recessive plants in a BC2F2 population derived from a cross of Shuhui527×Xiaoli and backcrossed with Xiaoli as the donor parent.

对F2和BC2F2 群体籽粒大小形状和千粒重的遗传分析表明，回交能将大部分对目的基因效应具有干扰修饰作用的微效基因多态性除去，从而有利于对目的基因型的准确鉴定；在F2和BC2F2群体中只发现两类籽粒长短表现型，即短粒和长粒，并且二者分离比例符合3：1的典型一对等位基因分离比例。

Lysine content, kernel phenotype, zein accumulation and opaque-2 gene sequence of four maize inbred lines (CA335, CA339, Lu2548 and Qi205) were investigated in this study. These QPM inbred lines as the donor of Opaque-2 mutant gene (o2) respectively, were backcrossed to introgression o2 into elite maize inbred lines based on marker-assisted.

对CA335、CA339、山东2548和齐205等4个国内常用优质蛋白玉米自交系的赖氨酸含量、籽粒表型、醇溶蛋白积累及opaque-2基因的序列进行了分析；对不同自交系作为Opaque-2突变基因（o2）基因供体的分子标记选择效果进行了初步的比较。

The improved watermelon inbred line wbl 9 with less-branching is developed by using donor parent of wbl 1 with 1 cross, 2 backcrosses with superior inbred line 015 and 6 generations of pedigree selection.

用具有弱分枝性状的wbl 1作供体亲本，用优良的西瓜自交系015作父本，通过1次杂交、2次回交和连续6代的自交分离和纯化，育成了具有弱分枝性状的优良自交系wbl 9。

The cytoplasmic male-sterility was transferred into leaf mustard by inter-varietal hybridization and subsequent backcrosses using cms donor of tuber mustard.

采用榨菜细胞质雄性系为不育源，通过变种间杂交和回交的方法，转育叶用芥菜细胞质雄性不育种质。

The cytoplasmic male sterile line CMS96 was transferred into Chinese cabbage by hybridization and subsequent backcrosses using CMS donor of B.napus.

大白菜CMS96细胞质不育系是由大白菜株系与甘蓝型油菜细胞质不育源杂交、多代回交后获得的。

In the backcross breeding of maize, the donor parent is suggested for consideration at priority, and backcrossing only once is acceptable on the basis of strict selection of target traits in combination with determination of GCA.

因此，利用回交法改良玉米自交系，在选准供体亲本的基础上，回交1次后，在自交过程中加强目标性状的鉴定选择及配合力测定，可提高回交改良的育种效率。

Backcrossing of MAALs to the recipient parent results in plants containing short overlapping introgressions, which cover the entire donor genome.

它可以通过回交形成覆盖整个基因组的渗入系重叠群，用于建立以受体物种基因组为载体的外源物种基因组文库。

One of the oldest problems bedevilling the business is the practice of "tied aid"(ie, requiring some of it be spent in the donor country).

援助工作中存在的一个根深蒂固的问题是存在&附带条件援助&的现象。

Liapunov—Schmidt方法是分叉理论的最重要方法之一。

Be courteous -- even when people are most discourteous to you .

要有礼貌──即使当別人对你最不礼貌的时候。
