结果发现：异源子代的血清、肌肉蛋白和同工酶的电泳图谱与母本彭泽鲫相同而与父本海鲤显著不同，推测异源精子的作用可能是在DNA水平上对后代产生影响，这种影响没有表现在成体同工酶的表达上。

Results showed that hybrid seed were easier to obtain when barley was used as the female parent.

通过试验明确，以大麦做母本，小麦做父本，较易获得杂种种子。

Using plant AT-1found by kenaf breeding research group of institute of bast fiber crops Chinese academy of agricultural sciences in Sanya of Hainan province were used as female parent in crossing with 15-4, 04K1 and then backcrossed four times with male parent in order to select two high sterile male sterility.

利用中国农业科学院麻类研究所红麻育种课题组在海南三亚发现的红麻不育株AT-1做母本分别与15-4，04K1做杂交，再用父本回交4次，选育出2个高度不育的不育系。

Generally, two hybridization events have happened in the generation of gynogenetic crucian carp: the first one occurred about 6, 000 years ago when maternal ancestor of C. a. gibelio hybridized with males of C. a. auratus (ancestor of C. a. colored variety) and a diploid hybrid was produced; the second one happened over 10, 000 years ago, when the diploid hybrid was backcrossed with one of its parental population, by which the current triploid gynogenetic crucian carp emerged.

初步推断出东北雌核生殖银鲫是通过鲫鱼种群间的两次杂交产生的，第一次杂交是母本的银鲫同源种群与父本的彩鲫同源种群杂交，形成二倍体杂种；第二次杂交是二倍体杂种与两个祖先鲫鱼种群之一回交，形成了今天的三倍体杂种银鲫。

Dazicao, a native wheat variety with stripe rust resistance from Henan, China, was crossed with susceptible cultivar Mingxian 169 as the female parent. The F1 progeny was selfed to produce F2 progeny and backcrossed with Mingxian 169 to produce BC1 progeny.

以抗条銹病的农家品种大籽糙作父本、感病品种铭贤169作母本杂交获得F1代杂交种，F1代植株自交获得F2代种子，F1代植株与铭贤169回交获得BC1代种子。

Dazicao,a native wheat variety with stripe rust resistance from Henan,China,was crossed with susceptible cultivar Mingxian 169 as the female parent.The F1 progeny was selfed to produce F2 progeny and backcrossed with Mingxian 169 to produce BC1 progeny.

以抗条锈病的农家品种大籽糙作父本、感病品种铭贤169作母本杂交获得F1代杂交种，F1代植株自交获得F2代种子，F1代植株与铭贤169回交获得 BC1代种子。

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。

In the study,six microsatellite loci are used to analysis the genetic structure and geneticvariation of eight beef hybrid parents population(five breeds of male parent and three breeds offemale parent,and 172 beefs in total).

本研究利用6个微卫星位点，分析了8个肉牛杂交亲本群体(5个父本种群，3个母本种群，共172头牛)的遗传结构、遗传变异。

It was confirmed that facultative apomixes is existed in coffee species based on emasculating treatment, cyto-genetic observe and SSR marker detection.

细胞遗传学观察发现咖啡四倍体类型材料(2n=4x=44)的多胚和多胚苗中含有天然的单倍体胚和单倍体小苗(2n=2X=22)；去雄处理后，可见子房膨大，其中5份材料获得了果实和种子，初步说明无融合生殖现象的存在；对小粒种品种间杂交F1代个体的SSR分析，发现多胚苗中存在与母本图谱相同且不携带父本特异带的后代以及携带双亲特异带的有性后代，表明子代有仅来自母本的无融合生殖个体分离出来。 3 建立了咖啡无融合生殖的分子鉴别方法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
