遗传地

Many studies paid attention to dissect the genetic bases using different emendatory approaches from phenotypic variation to gene discovery, mainly containing QTL mapping, chemical mutagenesis etc. Especially, QTL analysis was executed for a lot of important quantitative traits.

我们可以沿着由表型变异去发现基因之路，更准确地剖析数量性状的遗传基础；尤其是对作物的许多重要的数量性状进行的QTL研究越来越受到重视。

The hardware evolution is an important aspect of genetic algorithms realization, because by using the self-adaptability and fault tolerance of the evolvable hardware, the circuit can adapt to the new condition automatically.

硬件进化是遗传算法应用的一个重要方面，利用硬件进化的自适应性和容错性，可使设计出的电路结构自动地适应未知的环境。

On this platform, membership function and fuzzy rules can expediently be designed arid optimized by genetic algorithm.

在该平台上可以方便地实现对隶属函数和规则集的设计并用遗传算法加以优化。

The results showed that autote traploid rice might be effectively improved by ion beam bio-technique, from which the new germplasm with hereditable twin-embryo seedling could be selected.

结果表明，利用离子注入技术可以对同源四倍体水稻进行有效地改良，由此可以获得具有遗传变异特点的新种质，其双胚苗特性随着自交世代的推进而得到保持。

The anlysis of UPGMA cluster among the five natural populations showed that: except the population of WY, the other populations have similar hereditarily,and the populations of TM,DH have the most similar hereditarily. 4 It suggested that the protected of natural populations should be combined with in situ and transferred because of a certain extent genetic variation among the natural populations.

通过对5个居群的UPGMA聚类分析显示：除了的亲缘关系较远之外，其他银杏居群显示出较近的亲缘关系，其中以和的亲缘关系最近(4)由于银杏不同居群间出现了相当程度的遗传分化，建议就地保护和迁地保护结合进行。

Some evidence indicates that the combination of extrinsic, intrinsic and genetic factors all play a role to cause the disc degeneration, with a progressive decrease in proteoglycan content leading to dehydration of the nucleus pulposus, and Type Ⅰ collagen begins to appear in the matrix, the ratio between Type Ⅰ and Type Ⅱ increases. All these cause the swelling pressure, disc height and the disc load bearing ability decrease. The disc progressively herniate and cause radiculopathy and myelopathy.

内因、外因及遗传方面的诸多因素导致椎间盘逐步退变后，其实质就是基质中蛋白多糖的减少，含水量降低，Ⅰ型胶原出现在基质中，Ⅰ、Ⅱ型胶原的比例明显上升，髓核呈纤维样改变，导致椎间盘的膨胀压降低，承重能力下降，椎间高度降低，椎间盘承受的重力不能平均地向各方向传递，致使纤维环疲劳、破裂、髓核突出，造成脊髓或马尾神经受压，引起严重后果。

The main duty and task have three points:①introduce 、 ingather 、 collect 、 conserve wildness plant 、 local plant 、 breeding resource and genetic material ;②manage seeds resource review 、 introduce 、 exchange 、 inspect 、 propagate 、 update 、 dispense 、 identify 、 appraise 、 utilize 、 finger mark and DNA sequence data ;③The center can supply to decision-making department with information about crop protection and research, to science research and agricultural production with information about resource and to social public with information about protecting biology diversity.

中心内设寒带植物基因资源保存中心、研究与评价中心、黑龙江寒地活体野生资源圃、功能基因库等。其主要职责任务是：①引进、收集、采集、保存植物的野生、地方品种、选育的种质资源和遗传材料；②管理种质考察、引种、交换、监测、繁种、更新、分发、鉴定、评价和利用、指纹图谱和 DNA 序列数据等；③为决策部门提供作物资源保护和研究的信息，为科学研究和农业生产提供优良种质和信息，向社会公众提供保护生物多样性的科普信息。

Five translocated populations harboured 1,3 or 5 monomorphic loci respectively,while no monomorphic locus in the source population.

结果表明，奠基者效应导致种群的遗传多样性水平较低，并且对于不同迁地种群，影响也不相同。

Therefore, exposure to the space environment could be used as a method for mutagenic seeds breeding.

故认为高梁干种子在空间条件下所产生的变异是可以稳定地遗传给后代，航天育种可以作为一种新的诱变育种方法。

The description in growth characters and genetic variation of 7 new clones of Populus Deltoides is given in this paper.
