抗病育种 meaning in Chinese
breeding for disease resistance
Examples
- Application of similarity - difference analysis on the evaluation of anti - insect cotton varieties
灰色关联度分析在甜菜抗病育种中的应用 - So , using the genetic engineering to breed the fungi - resistant varieties is a available method
利用基因工程进行抗病育种是一个有效的途径。 - Making anti - dis ease breeding researches of fish by transfer gene is a new direction in transfergene researches offish
通过基因转移进行鱼类抗病育种研究，是鱼类转基因研究中的一个新的方向。 - A major component of wheat breeding programmes is to incorporate disease resistance , particularly to the various leaf and stem diseases , the races of which frequently change and genetic resistance continually breaks down
小麦育种项目的一个重要部分是抗病育种，特别是针对各种叶和茎病，致病菌系经常改变，致使小麦的遗传抗性不断地失效。 - Introduced infected by the turnip mosaic virus . there are many useful objective genes can be used in vegetable genetic transformation , but the research work of chinese cabbage genetic transformation is little . the reaserch on transforming chinese cabbage using agrobacterium - med ated method has n ' t been report at home and abroad . ln the test , tumv - cp gene was transferred into chinese cabbage ( brassica campestris l . ssp . pekinensis ) via agrobacterium - mediated method . a high effective regeneration and genetic transformatin system has been established , the detection by the method of molecular biology , has proved that the regenerative plants are transgenic plants and the target genes have been expressed transgenic plants partly . meanwhile transgenic progenies were traced and investigated so that heredity , stability and expression of target gene were researched . the virus resistant , stable plants were expected to obt ain so that theoretical base can be established for chinese cabbage breeding by gene engineering
利用农杆菌介导法转化大白菜抗病基因的研究工作在国内外未见报道。本课试验采用农杆菌介导法将tumv - cp基因导入大白菜中，建立了高效的大白菜离体再生、遗传转化体系，并对转基因植株进行分子生物学检测，证实得到的再生植株为转基因植株，目的基因已在部分植株上表达。同时，对转基因植株的后代进行检测，分析该基因所控制性状的遗传稳定性以及基因表达情况，为大白菜基因工程抗病育种提供理论依据。
