绵羊微卫星标记与部分毛用性状的关系研究

根据Genbank在绵羊1、6号染色体上选取了5个微卫星基因座,对待测绵羊群体所有的表型数据资料按基因型分组进行方差分析和多重比较后,得出结论: OarJMP8可以对羊毛自然长度性状进行标记。BM6438和BM6506可以对羊毛细度进行标记。在绵羊六号染色体上的OarJMP8附近存在控制羊毛自然长度的QTLs;在绵羊第1号染色体的BM6438和BM6506区域可能存在控制羊毛细度的QTLs。     

体育专业大学生上网族人格特质的调查研究

通过对体育专业大学生上网状况及卡特尔16PF问卷测验的调查，分析了体育专业大学生上网族的一般特点和人格特质构成。研究表明，体育专业大学生上网族具有敏感性、紧张性、幻想性较高，有恒性、世故性较低的人格特点。     

论文学功能系统与特质

传统的作品功能观把本视为学功能的发生源，把读视为学功能作用的被动对象，本提出：学功能必须在具体的学活动中才能产生，学活动是学功能的发生源。学功能联系于学活动的动态开放整体的流程，并对投身于学活动的一切实践主体（作与读）产生系统效能，学功能系统由认知，净化，愉悦，生命四个各具丰富内涵的子系统构成，并通过系统质的审美化合指向人本身，指向人自身的丰富与完善，指向人的诗意人生，因此，学功能是学之人学本义的回归。     

兼语句与其他句式结构的区别－现代汉语特殊句式辨析之二

兼语句是现代汉语的一种特殊句式，对它的研究，早在王力的《中国现代语法》就已开始了，而且主要涉及到兼语句的结构特点及扩缩存废问题。本着重从兼语句的结构特征、语义特征与其他句式结构的比较中区别出这一句式的特征来。     

花粉管通道法转基因对小麦主要农艺性状的影响

采用花粉管通道法介导外源耐盐基因SeNHX1导入4个小麦品种（品系）BN-64、YM-34、BM-1和AK-58中,并对转基因D0代的主要农艺性状进行了统计分析.结果表明,与对照相比,转基因D0代植株的种子（D1代）千粒重、株高、穗长、旗叶面积均有所提高;D0代植株与对照组相比,株高差异均达到显著水平,甚至极显著水平;穗长除BM-1差异不显著外,其余受体均达显著水平.叶面积差异均达到显著水平;叶长除YM-34外,其余受体差异均达到极显著水平.叶宽与受体相比均无明显差异.     

陆地棉F_2代单株选择的主成分分析

以抗虫棉品种和非抗虫棉杂交,在选择的条件下对F2代单株性状采用主成分分析的方法,就综合农艺性状对产量性状的影响进行了研究.结果表明：前5个主成分因子累积方差贡献率达74.95%,基本反映遗传信息.各主成分分析结果依次为：结铃性因子、形态因子、铃重因子、衣分因子、营养生长因子.依据主成分评价,较为理想的杂交F2代抗虫棉单株应是第1主成分较大,第2主成分适中的品种,即以果节数、果枝数和结铃数多,果枝夹角、株高和铃重适中的类型.通过5个主成分的总得分,构建出新的一个F2代单株选择指数,可以此作为F2代单株选择的依据.     

浅析大五人格特质和社会群体地位的关系

个体的人格特质和他在社会群体中的地位存在一定的关系。人格大五的每一维度在个体获得社会地位中的作用不同。外倾性对个体的地位获得有很好的预测作用 ,而神经质则不利于个体获得社会地位 ;宜人性和社会地位之间的关系 ,目前尚无定论。在非正式社会群体中 ,个体的责任心、开放性和社会地位获得没有关系。     

Crossbreeding parameters for fertility traits in a rotational crossbreeding between Landrace and Piétrain pigs

The reproduction characteristics of 343 sows in six different breeding groups were analyzed to estimate the crossbreeding parameters. The results indicated that the ovulation rate and the weights of uterus and ovary are mainly determined by the additive genetic effects while the nonadditive genetic effects play an important role in embryonal traits and litter performance. The heterosis effects in the first litter are larger than those in the second litter because of heterosis x environment interaction. The results also showed the existence of a highly significant maternal heterosis effect on the fertility traits of sows.     

Genetic analysis for brix weight per stool and its component traits in sugarcane （Saccharum officinarum）

Brix weight per stool (BW) of sugarcane is a complex trait, which is the final product of a combination of many components. Diallel cross experiments were conducted during a period of two years for BW and its five component traits, including stalk diameter (SD), stalk length (SL), stalk number (SN), stalk weight (SW), and brix scale (BS) of sugarcane. Phenotypic data of all the six traits were analyzed by mixed linear model and their phenotype variances were portioned into additive (A),dominance (D), additive×environment interaction (AE) and dominance×environment interaction (DE) effects, and the correlations of A, D, AE and DE effects between BW and its components were estimated. Conditional analysis was employed to investigate the contribution of the components traits to the variances of A, D, AE and DE effects of BW. It was observed that the heritabilities of BW were significantly attributed to A, D and DE by 23.9%, 30.9% and 28.5%, respectively. The variance of A effect for BW was significantly affected by SL, SN and BS by 25.3%, 93.7% and 17.4%, respectively. The variances of D and DE effects for BW were also significantly influenced by all the five components by 5.1%～85.5%. These determinants might be helpful in sugarcane breeding and provide valuable information for multiple-trait improvement of BW.
