It is interpreted that the correlation structure of the allelic polymorphism data contains null correlations introduced by "closure" and the statistical distribution of the data is not normal because of its constant row sum,which resulted in great difficulties in analyzing the data with traditional multiple linear statistical methods such as principal component analysis,factor analysis,cluster analysis and canonical correlation analysis.

长期以来，对于多维基因多态性数据的多元统计分析，如计算遗传距离时所用的聚类分析、分析群体遗传结构时所用的主成分分析、因子分析和典型相关分析等，一直应用为无约束条件数据而设计的经典多元线性分析方法，并没有注意基因多态性数据的"闭合效应"所带来的问题。

EST similarity analysis was finished by comparing sequences with BLASTx searches in NCBI. The results showed that they are proteins involved in biological processes such as energy metabolism and RNA molecular level regulation. Some of them are enzymes and structural proteins in the cell. This study provides useful information for future studies on molecular mechanism of filament coloring and for breeding new silkworm variety that spin color cocoons.

同时还初步发现几个有进化生态学意义的现象：(1)矿渣极强的重金属选择作用和环境隔离条件可能导致新物种在短期内形成；(2)自然选择可能在物种以上层次发挥作用；(3)不同环境因子对微生物生物量、抗性细菌比例、物种和遗传多样性等生物指征的作用不同；(4)不同的生物特征对环境因子修饰作用的敏感程度也不一样。

However the three mentioned analysis methods has been so far assured only available to high pathogenic pathotype identification, which was probably associated with the high expression of gene related to high pathogenicity, on the other hand, pathogenicity differentiation of Cercospora zeae-maydis was probably controlled by some complex factors regulated by by polygenes.

相比较而言，只有强致病类型菌株利用三种方法进行鉴定有一定程度的相关性，这可能与强致病类型致病相关因子在蛋白质和DNA水平上的表达强度高有关，另一方面可能是有复合因子控制灰斑病菌的致病性分化，这恰好反映出该病菌的抗性遗传是由多基因控制的特点。

Diopter, corneal curvature, depth of anterior chamber and the axial length of the eyes were measured. We calculated the concordance of hyperopia, intrapair correlation coefficient and heritability index of monozygous and dizygous twins.

调查了同卵和异卵双生子的屈光度、角膜曲率半径、前房深度、眼轴长度，计算了远视的一致率，同卵和异卵双生子的组内相关系数及遗传指数等项目，证实远视眼是一种多因子遗传病，它的发生除了与多个遗传性状如角膜曲率半径、前房深度、眼轴长度等有关外，还与环境因素有关。

Then, concerning the difficulty of ascertaining hysteresis time of piezometric tube, Genetic Algorithm-Radial Basis Function Neural Network model is developed according as the method that reservior level is rectilinear correlation with piezometric tube level, which not only could be calculated by computer but also is showed logical and feasible.

针对以往监测模型预测精度难以保证的的问题，本文在分析比较了几种土石坝安全监测预报模型的基础上，提出了一种新的安全监测预报模型——遗传回归模型，该模型通过遗传染色体对建模因子进行优选，并在适应度函数中综合考虑模型拟合精度与预测精度平衡。

The project implemented a systemic investigation to the pupa period of wild silkworm comparatively, which from Shanxi, Jiangsu, Sichuan, Chongqing, Guizhou provinces and so on. According to the investigation, the pupa dormant characteristic of Shaanxi wild silkworm was found, and the individual, which pupa period was more than two months was selected. Through the hybrid genetic analysis we found that the characteristics for a long period of pupa was controlled by polygene and genetic recessively and strongly influenced by environmental conditions at the same time. To compare the performance of pupa period of the pupa dormant wild mulberry silkworm, we designed different ecological conditions. The result indicating that the temperature is the main factor in the ecological impact, but the pupa period was extended at the same temperature conditions, indicating that the additive effects of the environmental factors.

本项目实施，系统调查比较了陕西、江苏、四川、重庆、贵州等省市的野桑蚕的蛹期经过，发现了陕西野桑蚕的蛹休眠特性，筛选获得了长达2个月以上的蛹期经过个体；通过杂交遗传分析，发现长蛹期特性表现为隐性遗传，受多基因控制，同时受环境条件的强烈影响作用；通过设计不同生态条件比较蛹休眠性野桑蚕蛹期经过的表现，表明温度是主要的生态影响因子，但相同温度的野外型条件下蛹期经过延长，表明受到环境因素的综合作用。

In this study, 105 TDFs were in silico mapped in the rice high-density linkage map. Nineteen TDFs were mapped to the quantitative trait loci regions for root growth under water-limited conditions in, at least, two of three rice populations derived from three crosses with the same parent of Azucena (Bala×Azucena, IR64×Azucena and IR1552×Azucena). Four of 19 genes (T37, L16, T17 and T7) were mapped based a RIL population of IR1552×Azucena by southern blot analysis. Five genes encode putative or hypothetical protein. Other 14 genes were similar with known genes in databases including expansin (OsEXP2), late embryogenesis-abundant gene , an SR-related protein essential for spliceosome assembly (SART1), autophagocytosis protein , bHLH protein, fruit-ripening protein similar to ASR, nickel-binding protein 2A, DNA-binding protein, pyruvate dehydrogenase kinase , stomatin-like protein, SR1 induced by sucrose starvation, vacuolar protein sorting protein (VSP33a), gibberellin action negative regulator and retroelement.
