With this inerratic change for the power of QTL detection,suitable experimental sample size could be roughly determined in practice pursuant to the degree of selection in the population of interest prior to experiment in order that the statistical power for QTh mapping would not decline because of the presence of selection in the population.

这种偏差根本上是由QTL基因型与多基因之间负的连锁不平衡以及QTL与标记之间的连锁不平衡所造成的。 2）目前QTL定位实践已找到了一些具有育种意义的主效位点。

In this study 2mG2-epsps gene was used to be a selection marker gene, and a series of experiments were designed for determining the time of their screening and selection pressure. The results showed that 1 mM glyphosate isopropylamine and 15 days screening can be effectively inhibited non-transgenic maize callus tissue differentiation. So this research work has provided a safe and effective screening system for corn and other monocotyledons crops.

实验中以2mG2-epsps基因作为筛选标记基因，为确定其筛选时间及筛选压力，进行了玉米愈伤组织对不同浓度草甘膦的抗性实验，确定向培养基中添加浓度为1mM的草甘膦异丙胺盐筛选15天能有效的抑制非转基因玉米愈伤组织的分化，本研究的再生植株的阳性率为45%，为玉米及其它单子叶作物转化提供了一种有效、安全的筛选体系。

Libellula had different resistance to different races and Xiannong 4 was susceptible to all the races except CY18 and CY22. Resistant components had significant variances among different cultivars, races and cultivar×race. And Libellula had strong selection on different races, while the selection of Xiannong 4 was weaker than that of Libellula.
