可杂交的

This lends weight to the theory that a viable hybrid population was sustained by interbreeding over a long time.

这无疑是对如下理论的支持：杂交后产生的可育杂合群体可以维持相当长的时间。

IL-1βmRNA expression in the developmental brain in Wistar rat: IL-1β mRNA in hippocampus, cerebral cortex and subcortex was detected by postnatal day 1 and gradually increased with development, reached a peak at postnatal day 21, and then gradually decreased to lower level at adult; In P77PMC rat, IL-1β mRNA expression was similar to Wistar rat before postnatal day 14, then gradually increased and surpassed Wistar rat at postnatal day 28, reached a peak in adult.

原位杂交显示谷氨酸诱导Wistar大鼠惊厥和P77PMC大鼠听源性惊厥后脑内IL-1βmRNA表达情况。结果发现，两种不同惊厥模型大鼠惊厥后脑内IL-1βmRNA表达存在明显的差异。谷氨酸引起惊厥诱导脑内皮层、海马和丘脑IL-1βmRNA表达增高的程度远较P77PMC大鼠听源性惊厥为低，而且惊厥后IL-1βmRNA表达增加较慢，于4-8h达高峰，而听源性惊厥可于惊厥后2h迅速达高峰。但两种形式惊厥诱导脑内IL-1βmRNA表达最高的部位均是海马。

In this research , by using of genomic in situ hybridization , random amplified polymorphism DNA technology and three specific SCAR molecular markers, the author analyzed wheat hybrid generations carrying the desired genes that were resistant to take-all, BYDV and/or powdery mildew, and developed some alien chromosome addition and translocation lines that were important in breeding practice, and some specific molecular markers that could be applied in marker-assisted selection.

本研究运用GISH、RAPD和SCAR分析方法，对抗全蚀病、黄矮病和兼抗黄矮病白粉病的小麦杂交后代材料进行分析，获得了一些对育种实践有重要意义的易位系、异附加系材料和几个可用于辅助育种的特异性分子标记。

Then in order to improve the efficiency and accuracy of numerical computation, the author developed hybrid spline interpolation, automatically varia...

然后为了提高数值计算的精度和效率，作者又根据二次样条的特点，提出了杂交样条插值、可变节距样条求积和自适应的样条求导等新方法。

In order to clarify the rules of POD isoenzyme in the hazelnut, identify their blood relations between female, male and filial generations and select the superior parents for cross-breeding, we have studied the characteristics of peroxidase isoenzyme which are distributed in the 34 hazelnut varieties or lines by polyarclamide gel electrophoresis, The results showed that:POD isoenzymes of Corylus heterophylla Fisch, Corylus avellana L, and the hybrid of Corylus heterophylla Fisch × Corylus avellana L had obvious difference; some hybrids had lost P10 spectrum band of parents; the enzyme spectrum of 32 hybrid hazelnuts produced 'new hybrid spectrum bands'that could be considered as a mean to identify hybrids.

为了阐明过氧化物同工酶在榛品种中的分布规律，探讨平榛、欧榛及其杂种榛之间的亲缘关系，选育优势杂交亲本，本试验采用聚丙烯酰胺凝胶垂直电泳，研究了34个榛品种成熟叶过氧化物酶同工酶酶谱特征，结果表明：平榛、欧榛及其平欧杂种榛品种间酶谱具有较大差异；有的杂种品种遗失了父母本共有谱带P10；32个平欧杂种榛品种出现了双亲所不具有的新酶带，可作为鉴别杂种的一条途径。

Besides, there still have never been reported about the situation of wild species originated from China in evolution of strawberry, research on cytogenetics of hybrids from the cross of wild species originated from China with cultivars of Fragaria will also be helpful for understand the relationship between wild species and cultivars and strawberry origin and evolution.

另一方面，原产我国草莓资源在草莓属进化中的作用至今尚未见报道，通过种间杂交及细胞遗传学研究可有助于探明草莓种质间的亲缘关系，为了解草莓的起源和进化提供参考。

So it is very necessary to study variances of Chinese Meretrix meretrix germplasm resources and their molecular genetic bases for their lasting utilization,sustained and healthy development of aquaculture industry. In this study, the genetic bases and their variances of representative populations of Meretrix clam were investigated through phenotypic traits and on the molecular level by quantitative genetic methods and molecular marker analysis technique.

本研究从表观性状和分子水平上探测我国文蛤种质资源的遗传基础和变异水平，旨在深入了解我国文蛤的种质状况并为其保护和可持续利用提供依据；在此基础上，通过杂交选择育种实践，分析和探讨文蛤由此获得杂种优势水平，为养殖文蛤的遗传改良和新品种培育提供理论指导。

The set of probes were then hybridized with genome DNA immobilized on the nylon membrane.

该方法根据所检测的DNA序列，制备若干具有通用引物的PCR产物作为可扩增探针组，与固定在尼龙膜上待测的基因组DNA杂交。

The results at molecular level provided a feasible research foundation for germ plasma identification, genetic diversity analysis and hybrid parents selection in rice breeding.

这些DNA分子水平的结果可为水稻种质资源的鉴定、遗传多样性分析和水稻育种工作中杂交亲本的选择提供科学依据。
