选用来自贵州黎平马褂木优良种源的23个优树自由授粉家系，设置低氮素和高氮素2种水平的盆栽试验，以研究马褂木家系苗生长对氮素营养的遗传反应差异及所受遗传控制。

So,the genetic distance could be used for the choice ofparents and for the heterosis prediction in cross breeding of Liriodendron.

因此，花粉品质、杂交亲和力和一般配合力应作为亲本选配的重要依据；基于RAPD标记的亲本间遗传距离与子代1年生苗高和地径生长量均表现为二次曲线相关，复相关系数分别为0.8235和0.5090，达极显著(H，P＜0.01)和显著(GLD，P＜0.05)程度，说明利用亲本间遗传距离进行鹅掌楸亲本选配和杂种优势预测是可行的。

In microevolution, it provided a number of molecular marker systems for the research of genetic variation in plant natural populations, greatly facilitating investigation of the evolutionary mechanisms under natural conditions.

它们在研究植物天然居群遗传变异的规律、揭示进化机制方面已展示了巨大潜力，这是进化生物学中最重要的研究领域之一，也是物种遗传多样性保护的理论基础。

The results revealed that nine of the fourteen Y-specific markers cannot be used for investigating the swamp buffalo Y chromosome genetic diversity because of the reasons specified below: three microsatellites markers (INRA008, UMN0103 and UMN0504) were single allele and monomorphism, three (UMN1113, UMN0304 and BC1.2) indicated three alleles respectively but mornomorphism, and the other three (UMN0920, UMN0307 and UMN3008) showed irregular ladder-like bands. Only the remaining five microsatellites (INRA124, INRA189, BM861, PBR1F1 and UMN2001) indicated polymorphisms, and thus can be applied to study the swamp buffalo Y chromosome genetic diversity.

结果表明，3个标记（INRA008，UMN0103和UMN0504）只有1个等位基因，表现为单态；3个标记（UMN1113，UMN0304和BC1.2）均为3个等位基因，但呈单态；3个标记（UMN0920，UMN0307和UMN3008）呈现无规律的梯状条带，所以这9个标记都不适用于水牛的Y染色体遗传多样性研究；只有5个标记（INRA124，INRA189，BM861，PBR1F1和UMN2001）具有多态性，表明适用于水牛的Y染色体遗传多样性研究。

Several typical benchmark function numerical experiments demonstrate that it is improved on the solution precision and increased convergence speed.

针对标准遗传算法的缺陷，出现了各种各样的改进方法[1~10]，尤其是利用混沌理论改进遗传算法的性能值得关注。

Tenth. A series of mathematical model of genetic mechanism of common population have been established,they are mathematical description of genetic mechanism of common population, so the population that the population genetics researching have extended from panmixia population, inbreeding population,selfing population to common population. It will start the new research territory of population genetics and promote its development.

本文建立了普通群体遗传机制的一系列数学模型，这是对普通群体遗传机制的数学描述，它使群体遗传学所研究的群体由随机交配群体、近亲交配群体、自交群体扩展到普通群体。

Analyses were carried by Maximum parsimony method, using the allied genus paper mulberry as outgroup.

基于探讨桑属植物种群间遗传变异规律，采用显性分子标记RAPD技术对我国桑树现行分类的15个种4个变种及近缘属的48份供试材料进行了桑属种群的遗传结构分析。

Prom the differences among these hybrids, the basic genetic parameters of quatitative characters were estimated for the two parent's population apart.

优良自交系亚总体各性状的遗传方差则普遍减小，说明其遗传基础更为狭窄。所以，为了不断地育出更好的自交系间杂种，迫切需要补充新的基因源。
