查询词典 spur blight

The application of MAS in rice bacterial blight resistance and rice blast resistance breeding programs showed it is efficient in selecting individuals containing resistance genes from a crossing population, reducing the scale of subsequent experiment, and breeding variety with pyramided genes.

以抗白叶枯病基因及抗稻热病基因为例，利用分子标志辅助选拔进行杂交后裔族群的筛选，能有效地自杂交后裔族群中筛选出具有抗病基因的个体，并可缩小病原菌接种的试验规模，快速地育成堆叠抗病基因的品系。

Senescence-inhibition IPT gene, resistance genes to bacterial blight Xa23 and to blast Pi-b were pyramided in rice by marker-assisted selection. According to molecular detection and identification of resistance, 16 FI plants carrying IPT genes and Xa23 were obtained from the multi-cross.

本研究采取分子标记辅助选择的方法，在水稻中将抗衰老IPT基因与抗白叶枯病基因Xa23及抗稻瘟病基因Pi-b进行聚合，通过分子检测和抗病鉴定，在3个复交组合中获得了16株IPT基因与Xa23基因聚合的复交F_1植株。

The research activities were briefly highlighted as follows: They were yield nurseries, observational nurseries, tolerance/resistance screening nurseries (cold, drought, salt/acid, blast. bacterial leaf blight, rice tungro virus, brown planthopper and white-backed planthopper resistances). These studies with evolving technologies are aimed at improving crop production.

其研究活动着重于以下几方面：产量反应，生长观察，耐性/抗性筛选（抗冻、抗旱、抗盐/酸、抗稻瘟病、白叶枯病、水稻塘古罗病毒、褐稻虱和白背飞虱），其目的就是为了提高产量。

The apple trees were blight ed by frost.

苹果树因严寒而枯萎。

There is a new northern bean made available to farmers and breeders that can resist common bacterial blight – and it is high-yielding too. Named "ABC-Weihing", the bean cultivar was developed by University of Nebraska bean breeder Carlos Urrea, and Phil Miklas, a geneticist at the Agricultural Research Service using marker-assisted selection. The new bean variety resisted eight strains of bean rust and all non-necrotic strains of bean common mosaic in greenhouse tests, and also had an average seed yield of 1,869 pounds per acre.

美国农业部网站2007年7月6日消息，美国内布拉斯加州大学豆类育种专家Carlos Urrea 以及美国农业研究服务局的遗传学专家Phil Miklas 使用标记辅助选择的方法研究出了一种新的北方豆类品种&ABC-Weihing&，这种新品种在温室测试中可以抵抗八种菜豆锈病以及所有未坏死的菜豆普通花叶病毒，并且可以达到每英亩平均1869磅的产量水平。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
