The important role of the series information service to the success of Hybred Rice breeding, and to its succossful transformation into productivity is reviewed in this paper both theoretically and practically, including the role in subject selection and tackling key problems in research. In addition, information report, dissemination and translation has sped up the procedure of decision-making, research and production of Hybred Rice, and of the sp- reading of the technology worldwide as well. It is aslo illustrated with exa- mples that paid service will inhance the activity of scientific and technolo- gical information institutes.

本文试图从理论与实践的结合上论述我国杂交水稻研究成功及其转化为巨大生产力,是与农业科技情报工作对它的系列服务分不开的。首先,农业科技文献工作为研究选题发挥了先导作用和启迪职能,为其胜利地攻关提供了重要参考、科学依据和有效借鉴;其次,科技情报报道传递和翻译工作,也加快了杂交水稻科研、生产和决策管理的进程以及杂交水稻技术在世界的传播速度。本文还列举事例揭示了为杂交水稻科技和生产开展有偿服务对增添科技情报单位的活力具有重要作用。

Hybrid rice breeding can be devided into three developmental phases,i.e,three line system,two line system and one line system in terms of breeding methodology,and inter-varietal heterosis,inter-subspecific heterosis and distant heterosis in terms of enhancing heterosis level.The superority of two line system over three line system is:(1)The choice for restoring lines greatly broadened;(2)no negative sterile cytoplasmic effect;(3)easy development of new sterile lines.So far,more than 20 practically usable PGMS...

Hybrid rice breeding can be devided into three developmental phases,i.e,three line system,two line system and one line system in terms of breeding methodology,and inter-varietal heterosis,inter-subspecific heterosis and distant heterosis in terms of enhancing heterosis level.The superority of two line system over three line system is:(1)The choice for restoring lines greatly broadened;(2)no negative sterile cytoplasmic effect;(3)easy development of new sterile lines.So far,more than 20 practically usable PGMS and TGMS lines and 7 two-line hybrid varieties have been cerificated.The problem of low and unstable multiplication yield of TGMS line with low sterility inducing temperature has been solved through running cold water irrigation.The special procedure for purifying and producing foundation seeds of PGMS and TGMS lines have been established and proved to be effective.The two line hybrid rice technology has been ripened.Pioneer combinations proformed very well in farmers'field and outyielded the three line check by about 10%. It is predicted that two line hybrid rice will cover 4.5 million ha and the grain yield increased will amount to 2.5 billion kg by the end of this century.

从育种上讲,杂交水稻育种可以分为三系法、两系法和一系法三个发展阶段;从利用杂种优势水平来看,杂交水稻育种可以分为品种间、亚种间和远缘杂种优势利用三个发展阶段。与三系法比较,两系法具有配组自由、种子生产成本低、无不育细胞质负效应、易转育新不育系等优点。迄今为止,我国已育成20多个通过省级鉴定的实用光温敏核不育系,7个通过省级审定的两系法杂交稻组合,解决了低温敏不育系繁殖产量低而不稳的难题,实施了光温敏不育系提纯和原种生产的程序,两系法杂交水稻技术基本成熟配套,先锋组合在大面积示范中表现良好。预计本世纪末,全国可推广333.33万hm2两系杂交稻,增产粮食25亿kg

The current status of food production in the world and the background and foreground in export of Chinese hybrid rice technology were analyzed. The strategy for exporting Chinese hybrid rice technology was proposed and the suggestions were given to solve the existing concrete obstacles or problems in the export of Chinese hybrid rice technology.
