杂种

The progress of the biotechnology provides the opportunity to elucidate the mechanism of heterosis in genome level.

生物技术的发展为直接在基因组水平上研究杂种优势机理提供了基础。

However, no significant correlations between genetic distance and traits or their heterosis were found.

但品系间遗传距离与各性状及其杂种优势率之间没有显著的相关关系。

Our results showed that some of genes may play a role in heterosis response either through increased or decreased expression.

结果表明，有些基因通过增强或减弱表达在杂种优势现象中起一定作用。

Kenaf is one of the most important fibre crops, with obvious heterosis.

红麻是一种重要的纤维作物，杂种优势显著。

The Heterosis Utilization is the important method of raising the rapeseed production level.

杂种优势利用是提高油菜产量水平的重要手段。

Utilization of heterosis in rapeseed is an efficient path to enhance yield,improve quality,and to strengthen resistance.

杂种优势利用是提高油菜产量、品质和抗性的有效途径。

Besides, the relationship between〓expression of maize and heterosis were analysed by means of cDNA-AFLP technique.

并且利用cDNA-AFLP技术探讨了玉米基因表达与杂种优势的关系。

These results showed that there were closely relationship between differential expression genes and heterosis at seedling stageof cotton.

上述结果表明，苗期基因表达差异与杂种优势的形成存在着密切关系。

The results showed that there existed commonly the heterosis in crosses of pumpkin inbred lines.

结果表明，南瓜自交系的杂交后代普遍存在杂种优势。

A synthetic hexaploidy wheat with resistant to preharvest sprout and hard glume was employed to cross with a common wheat line with character of susceptible to preharvest sprout and normal glume hardness, and then built up the F3 population, aiming at studying the relationship between the resistance to preharvest sprout and its glume hardness.

本研究利用抗穗发芽、硬颖壳的人工合成小麦与正常颖壳硬度、穗发芽的普通小麦杂交构建的杂种F3代群体，研究穗发芽与颖壳硬度之间的关系。

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。
