Pesticide management is characterized, in terms of government responsibility, by an increasing need for flexibility to cope with fast change in science, technology, agricultural practice and environmental policy. The feasibility study in question was started at the end of 1974, when it became clear that the variety of conventional information systems often caused delay, especially in the administrative follow–up of the official procedures with which government is involved. This concerns approval and registration as well as providing pesticide information to quite a variety of interested parties, such as industry, importers, dealers, users of pesticides and government agencies (Plant Protection Service, Extension Services, Public Health and Environment Authorities, Labour Inspectorate, etc.). The computer–based pesticide management information system which is being developed now by a multi–disciplinary project–group should meet the needs of all those having government responsibility in the field of pesticide management. It is planned as an on–line, geographically dispersed retrieval and storage system with terminal facilities for all users. The system is to be controlled by the Pesticides Bureau of the interdepartmental Committee for Phytopharmacy.  相似文献

小麦赤霉病抗性QTL分析   总被引:14,自引:1,他引:13  
以小麦赤霉病抗源望水白与感病品种Alondra杂交产生的104个重组自交系为材料,采用JoinMap®3.0软件构建了含有2个RAPD、109个SSR和105个AFLP标记共25个连锁群的遗传连锁图,其中24个连锁群可以确定为相应的染色体;采用自然发病和土表接种方法,对该重组自交系群体在建阳和苏州进行了连续两年赤霉病抗性鉴定,结果表明:  相似文献

用JoinMaP(R) 3.0初步构建小麦遗传连锁图   总被引:8,自引:2,他引:6  
以普通小麦品种“望水白”与“Alondra”杂交并通过单粒传方法获得的含104个重组自交系(F7)的群体为作图群体,采用JoinMap 3.0软件初步构建了含有2个RAPD、109个SSR和105个AFLP多态性标记的小麦遗传整合图谱。该图谱的遗传总距离为1241.4cM,含有25个连锁群,已确认其中24个连锁群相应的染色体,除3D染色体外,其余20条染色体均构建了遗传连锁图。A、B、D3个染色体组的染色体平均长度分别为75.1cM、59.6cM和45.8cM,每个染色体平均分布的多态性标记分别为11.3、13.8和5.5个,标记间的平均间隔为5.7cM,仍有25.8%的多态性标记未能构建进遗传图谱。  相似文献
