In this study, a clonally propagated FT population (F2CP) including 250 stable lines was obtained by vegetative propagation of F: seeds from a cross between Japonica Balilla and Indica Dular.

以该F_2CP为研究对象，在2000年和2001年共对20个重要农艺性状进行考察和统计分析，在2001年种植F_(2：3)家系群体进行相同研究，以便比较两个群体的表现。

In searching for RAPD marker linked to the genes controlling brachytic stem, 260 RAPD primers were applied to screen four parents of three combinations and RIL. Polymorphic bands revealed by the primer S-506 exhibited the best repeatability among all primers.

利用4个亲本和1个重组自交家系筛选260个RAPD随机引物，其中有1个引物S-506扩增出的多态性条带有较好的重复性。

RESULTS: Eight affected subjects had subnormal visual acuity due to high myopia. The results of colour vision tests were consistent with red-green CVD in six of these affected subjects. Fundus examination showed degenerative myopic changes characterized with generalized chorioretinal atrophy.Abnormal cone and rod dark-adaptation and diminished cone response in ERG were found in two subjects. According to family pedigree, it has been suggested that red-green CVD has X-linked recessive inheritance.

结果：患者8位均因高度近视视力下降，其中6例有红绿色觉缺失，眼底检查显示以弥漫性视网膜脉络膜萎缩为特征的近视改变。2例患者ERG检查出现视杆细胞的暗适应异常和视锥细胞的反应消失，根据家系，红绿色觉缺失属X连锁的隐性遗传。

This paper deals with the preliminary results on tissue culture and rapid propagation of Cinnamomum camphora.

本文报道应用组织培养育苗技术从樟树家系快速繁殖无性系植株的初步结果。

Japonicus used in this experimentation is matemal inheritance.5 Sequence analysis of mitochondrial 16S rRNA and COI gene and molecular phylogeny of four species of sea cucumber500 bp 16S rRNA and 540 bp COI fragment were obtained by PCR method from mitochondrial DNA of four species of sea cucumber, Apostichopus japonicus, Holothuria fuscogilva, Cucumaria frondosa and Mensamaria intercedens. Variable sites, nucleotide diversity, average number of nucleotide differences and average number of nucleotide substitutions per site were calculated to analyze sequence difference, and phylogenetic trees were constructed by the NJ and ME method.

结果显示在来自这5组家系的100个后代中仅检测到母本的单倍型，刺参的线粒体遗传模式表现为典型的母系遗传。5 4种海参16S rRNA和COI基因片段序列比较及系统学研究采用PCR技术对山东荣成、长岛、俄罗斯和日本的刺参，黄乳海参，北大西洋瓜参，二色桌片参的16S rRNA和COI基因片段进行了扩增和测序，分别得到了长度约为500 bp和540 bp的片段。

To search the genetic heterogeneity of ADPKD and to compare the clinical presentation between ADPKD type 1 and 2 in Shanghai Han population, develop a method of gene diagnosis by linkage analysis with microsatellite DNA tightly linked to PKD1 and PKD2 and make gene diagnosis of mutation carriers before cystogenesis, detect single nucleotide polymorphism of PKD2 and its frequence in Han population.

根据知情同意的原则，选取80名无亲缘关系的上海市汉族健康志愿者进行与PKD1和PKD2连锁的微卫星DNA多态性的研究，选取43个常染色体显性多囊肾病家系进行遗传异质性、表型差异研究及基因诊断。

ANOVA, Interval mapping and digenic interaction wereused to analyze the QTLs associated with disease resistance, seed total glucosinolate content and itscomponents.

通过对〓单株的基因型分析和〓家系的抗病性、硫苷含量的测定，对抗菌核病性、硫苷总含量及各组分进行了QTL定位和位点互作分析。

Abstract］ Objective To report the ultrasonocardiographic features of familial dilative cardiomyopathy in two families.

摘 要］目的阐述两家系扩张型心肌病的超声心动图特征。

And molecular genetic analysis was performed on DNA extracted from the twins Ⅳ-3 and Ⅳ-4 to identify whether they are monozygotic twins or dizygotic twins Results The family history was consistent with a maternal inheritance and the proband exhibited a typical clinical feature of LHON.

最后应用分子遗传学技术对该家系中的一对双生子（其中一人为先证者，另一个未患病）进行DNA多态性的比较分析以鉴定其卵性。

Results All affected individuals manifested with age-dependent seizures, combined with tremor, dyssynergia cerebellaris myoclonica and pyramidal sign.

结果 T家系患者临床表现为多种形式的癫痫发作、震颤、肌阵挛小脑协调障碍和锥体束征。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
