According to Mather and Jinks model, using generations mean analysis m eth od, the various kinds of gene effects and its percentage of gene-effect-square s um were estimated,and comparative analysis on the gene effects and the importan ce t o inheritance of characters was carried out between the supernumerary spikelet l ines.

黄毅以主穗小穗数在25～30个的二个普通小麦多小穗品系85DH5015、SW94-30921 与三个普通小麦品种组配成6个组合的P1、P2、F1、F2、B1、B2为材料，用世代均值法分析了6个性状的遗传模型并估算了各类基因效应值，比较分析了两个不同来源多小穗小麦品系六个性状各类基因效应的异同及其相对重要性。

Result The detection limit of the two systems were 0.1fg, equal to 2.31×10^4 copies, which was 10^2-10^3 fold higher than conventional PCR. By the constructed detection systems, the TCK and Tilletia cariesTul could be distinguished. The teliospore and mycelium of TCK in the infected wheat plant tissue also could be identified accurately and rapidly.

建立的两套定量PCR检测体系的检测下限相当，可达到0.1fg，对应的拷贝数为2.31×10^4个，检测灵敏度比常规PCR高2~3个数量级，均可成功鉴别出TCK与小麦网腥黑穗病菌Tilletia caries (DC Tul， TCT，并可快速准确检测小麦矮腥黑穗菌冬孢子和检测罹病小麦植株体内的侵染菌丝体。

However, the breadmaking experiment on wheat flour of 12 wheat varieties shows that the wheat protease has a remarkable effect on the breadmaking properties of wheat flour under the acid condition, which is in well connection with the quantity and quality of protein itself.

对小麦内源蛋白水解酶与小麦粉中蛋白质的水解作用和环境的pH值关系进行了研究，结果表明小麦内源蛋白水解酶在中性条件下，对蛋白质不产生强烈的水解作用；在酸性条件下，对蛋白质有显著的水解作用。

Up to date, QTL analysis of adult-plant resistance against powdery mildew has not been reported in China. In the present study, QTL mapping of APR was conducted using a doubled-haploid population derived from the cross (Fukuho-komugi × Oligoculm) and a F_(2:3) population from the cross (Bainong64 × Jingshuang16). The methods and main results are described as follows:1. A doubled-haploid population from an intervarietal cross between the Japannese cultivar Fukuho-kumugi and the Israeli wheat line Oligoculm was prouduced by means of wheat × maize crosses.

国内关于白粉病成株抗性的QTL分析尚未见报道，本研究开展了小麦白粉病成株抗性鉴定、遗传连锁图构建、白粉病成株抗性QTL分析，得到以下研究结果：(1)以抗白粉病的日本小麦品种Fukuho-komugi和以色列小麦Oligoculm杂交产生的DH群体为材料，利用313个SSR标记和37个RFLP标记，对Fukuho-komugi和Oligoculm的白粉病成株抗性进行QTL分析。

The wheat tribe Triticeae Damort., in the subfamily Pooideae, Poaceae, includes three of the most important cereal crops, i.e., wheat, barley, and rye, as well as many economically valuable forage grasses.

小麦族(Triticeae Damort。)属于禾本科的禾亚科，包含着与人类的生活密切相关的三种重要粮食作物，如：小麦、大麦和黑麦，小麦族还包含了许多有重要经济价值的牧草种类。

Safener increased the ALS activity and it also increased the GST activity of the two cultivars, which may enhance the metabolism of the herbicide, thus increased the tolerance to mesosulfuron.

本研究认为不同小麦对甲基二磺隆的敏感性不同，其敏感性可能与靶标酶ALS有关，安全剂提高了小麦ALS活力，也提高了GST的活力，增强了除草剂的代谢，从而增加了小麦对甲基二磺隆的耐药性。

Paste properties of starch of Nanyang color wheat under different concentrations of sodium carbonate, alum, salt or glucose were measured by Brabender viacometer. The viscosity property of starch paste and its influencing factors were discussed.

为了解食品添加剂对南阳彩色小麦淀粉糊特性的影响，采用Brabender黏度仪，测定南阳彩色小麦淀粉在添加不同碱面、明矾、食盐和葡萄糖后的黏度曲线，研究了这些因素对小麦淀粉糊化特性的影响。

The authors determined glutenin protein,soluble in acid glutenin protein, surplus protein content in 21 species of wheat and indexes of rheological characteristics and made sedimentation and bread baking test. By using stepwise regression and path analysis methods,it was further proved that prediction of bread baking quality of wheat by Surplus protein content is more precise than that by sedimentaion and approximately equal to that by the score of flour. So the authors suggest that the direct selection of ...

本试验测定了21个小麦品种的几种蛋白含量以及流变学特性指标，作了沉淀试验和面包烘烤试验，借助于逐步回归分析和通径分析方法，进一步验证了用剩余蛋白含量预测小麦烘烤品质与评价值相当，比沉淀值准确的结论，并建议在小麦品质育种及面包烘烤品质分析中，加强对剩余蛋白含量的直接选择。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
