杂交

They are now more eager to use scientific methods for farming.

以农民为例，他们现在更乐于使用科学种田法，由于种植杂交水稻的面积增加，单位面积的产量也增加了。

Scientific methods of farming, including development of sturdy, disease-resistant hybrid seeds and the use of machines, are responsible for the production increase.

产量增长的根本原因在于科学种田法，它包括强壮抗病杂交种子的培植和机械的使用。

As a result, Core gene was expressed in E.coli with yields of 20% of total proteins and it was a 31KD fusion protein on SDS-PAGE and Western-Blot, it shows that Core protein was highly expressed in E.coli;One fragment of 369bp could be seen on the gel of the Core gene PCR product. A band of 29KD could be seen on the Western-blot after induction of yeast containing pPICZaA-Core for 72 hours. This indicate that Core protein was secretively expressed in the Pichia pastoris with weak yields.

结果显示pBVIL1-Core的表达产物经SDS-PAGE分析出现一条约31KD的带，与预期融合蛋白的分子量相符，表达蛋白存在于包涵体中且表达量占菌体总蛋白的20%，Western-blot显示诱导后菌体在相应位置出现特异性杂交带，表明

For cross bred rice, the performance of this seeder is satisfying with high rate of single seed.

试验表明，本机在"V"型吸嘴下对杂交水稻的播种性能最好，单粒率相当高。

Most seedless grapes suitable for the eastern United States are descended from crosses with these two cultivars.

最适合于美国东部合适的无籽葡萄杂交后代这两个品种。

Eleven differentially exp ressed fragmentswere confirmed by bulked segregant analysis and reverse Northern blotting, further cloned and sequenced.

经过BSA 分析和反向Northern杂交鉴定，获得了11个差异表达的cDNA片段，并进行了克隆、测序和序列同源性检索分析。

Bulked segregant method and co-segregation analysis in F2 population were usedto screen molecular markers linked with TMS and LF genes,respectively.

根据8987与三个早熟品种的杂交F1和F2群体的播抽期表现和频率分布，显示8987还具有一对隐性长生育期主效基因。

A population of 48 individualswas developed from cross'91-42-51' ×'Ruiguang 2', and was used to find molecular markers linked to characters as peach or nectarine, yellow or white flesh, male sterility or male fertility by bulked segregant analysis.

以91-42-51 ×瑞光2号的杂交后代共48个单株为试材，采用集群分离分析法，对桃果实的有毛/无毛、白肉/黄肉以及无花粉/有花粉3 个性状进行了分子标记研究。

The methods of bulk segregant analysis , randomly amplified polymorphic DNA and sequence characterized amplified regions were used to analyze F〓 individuals of the hybrid IR24×78-15 and molecular genetic markers linked to Xa-min gene were identified.

同时，以IR24和78-15为亲本进行杂交（IR24×78-15），并采用分离群体分组分析法、随机引物扩增多态性DNA和序列特异性扩增区筛选与Xa-min连锁的分子标记。

Seismoscope made to make the world "all serve his wonderful", opened a new era of scientific principles of the earthquake; Chinese laser photo-typesetting system that allows Chinese characters printed goodbye to "lead and fire," History;"Hybrid Rice" to make rice production in a century added two times, to feed tens of millions of people.

地动仪的制成使世人"皆服其妙"，揭开了地震科学原理的新纪元；汉字激光照排系统，使汉字印刷告别了"铅与火"的历史；"杂交水稻"使水稻产量在一个世纪中增加了2倍，养活了数以千万计人口。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
