无融合生殖

Third,apomictic rice and C4 crop,were crossed to create new allopolyploid cultivars with high photosynthetic efficiency.

无融合生殖水稻和C4作物杂交创造高光效异源多倍体新作物。

Apomixis,wide compatibility,allopolyploidization were used to select allopolyploid rice and enlarge its range of inheritance and variation,and increase its output,quality and resistance to disease and pest by a big margin.

通过无融合生殖、广亲和、异源多倍体化的利用，选育异源多倍体水稻，增加它的遗传变异范围，大幅度提高水稻的产量、质量和抗性。3。

This paper presents a brief review of the current status of knowledge in the main fields of apomixis research.

目前大量的研究都在设法将无融合生殖作为一种重要的植物育种手段。

The current state of knowledge on the molecular and genetic basis of apomixis is reviewed.

本文对植物无融合生殖遗传机理和分子机理的研究进展作了综述。

First,using apomixis to establish a new method of rapid breeding.

利用无融合生殖建立快速育种新方法。

Second,apomixis and polyploidization were used to search new breeding method.

利用无融合生殖和多倍体化探索育种新途径。

Further studies are necessary to clarify a taxonomy complicated by hybridization and apomixis.

需要进一步的研究验证一种通过杂交和无融合生殖折叠的分类法。

The species present in China are not clear-cut and are also variable within themselves due to polyploidy and apomixis.

存在于中国的本种不明确，由于polyploidy和无融合生殖在他们自己内也是易变的。

The information will be useful for the development of apomixis technology and therefore has important implications for crops breeding.

本研究结果可作为建立无融合生殖生物科技之本土基础资料，并提供禾草作物育种时选材之依据。

But utilization of apomixis in breeding procedure could significantly shorten time of selection and fix heterosis.

然而利用无融合生殖特性进行育种将可能大大缩短育种年限，固定杂种优势。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
