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。

Generally speaking, most causes the blood disease which the skin hemorrhage, the menstruation increase, through inspections and so on routine blood test, marrow may be clear about the diagnosis basically, but to minority difficult case, then must through the special examination method, like the chromosome inspection, the gene order analysis, the blood platelet accumulation function determination be able to diagnose (my branch to apply the above method to diagnose rare May-Hegglin successively recently exceptionally with heredity telangiectasis sickness pedigree each example).

一般而言，多数导致皮肤出血、月经增多的血液疾病，通过血常规、骨髓等检查可基本明确诊断，但对少数疑难病例，则需通过特殊的检测方法，如染色体检查、基因序列分析、血小板聚集功能测定才能确诊（最近我科应用上述方法先后诊断了罕见的May－Hegglin异常和遗传性毛细血管扩张症家系各一例）。

In all 6 species, 5S rDNA was located at the paracentromeric region of a pair of middle-sized telocentric chromosome.

结果表明5S rDNA在6种石斑鱼染色体组中，均位于1对中等大小端部着丝粒染色体且靠近着丝点的位置上，种间和种内未观察到差异，在染色体上的分布模式基本一致。

The karyotype contains 12 pairs of metacentric, 3 pairs of submetacentirc and 4 pairs of subtelocentric chromosomes. There is no telocentric chromosome at all.

绢丝丽蚌的二倍体数目2n=38，核型公式为2n=24m+6sm+8st，NF=68，其中中部染色体12对，亚中部染色体3对，亚端部染色体4对，没有端部染色体。

Its chromosome number was estimated at 2n = 48; which consisted of 8 submetacentric and 40 telocentric chromosomes. The karyotype formula was described as 8 sm + 40 t with 56 fundamental arms.

计算其染色体数，结果为2n＝48，其中8条为近中央中结染色体及40条为端点中结染色体，核型公式为8 sm+40 t，染色体总臂数为56。

The karyotype pattern showed that the chromosome number of 2n = 48 contained two metacentric chromosomes, two submetacentric chromosomes, 44 telocentric chromosomes. The karyotype formula is 2 m + 2 st + 44 t and the fundamental number is 52. We will continue to make the karyotype analysis of other tunas in the future.

结果显示其染色体数为2 n = 48，其中2条为中央中结染色体，2条为近中央中结染色体，44条为端点中结染色体，核型公式为2 m + 2 sm + 44 t，染色体总臂数为52，未来将继续进行其它鲔鱼的核型分析。

The results showed as follows: The diploid chromosome number of Yanbian yellow cattle and Liyan hybrid cattle were 2n=60,the karyotype of bulls was 2n=60,XY,while cows were 2n=60,XX. 29 pairs of autosomes were telocentric.

采用外周血淋巴细胞培养技术、常规染色体制片技术和染色体C-分带技术，对延边黄牛(10♀，10♂)和利延杂交牛(14♀，15♂)两品种的染色体核型和C-带进行了研究。

Besides, NO.4, 6, 8, Z chromosome of domestic fowl were submetacentric, submetacentric, metacentric, metacentric, repectively, whereas those of quail were all telocentric.

结果表明，家鸡和鹌鹑染色体数目均为2n=78，但染色体的形态存在明显差异，主要表现在NO.1、NO.4、NO.6、NO.8和Z染色体上。

Objective :For the first time,the Karyotype and the meiosis chromosome of Testudo impressa are reported in the research.
