中文摘要: 杂交水稻的培育和推广为世界粮食安全做出了重要的贡献.本文概述了杂交水稻技术在孟加拉国、巴基斯坦、印度、印度尼西亚、菲律宾、缅甸、越南和美国等主要杂交水稻生产国家的发展历程,并重点分析了各地区杂交水稻研发的典型特征和限制杂交水稻进一步推广应用的主要问题.分析认为,杂交水稻在以上不同国家的推广应用基本上都经历了从引种到本地化育种以及性状改良等发展阶段,杂交水稻技术在这些地区的成功应用主要得益于新品种培育、制种技术的突破和农艺性状的改良.但是,当前杂交水稻在国外的发展仍然面临以下问题:杂交水稻亲本的遗传同质化程度高导致热带杂交水稻的产量优势不如温带杂交水稻;杂交水稻种子来源不稳定;杂交水稻制种产量低和种子质量难以保证;杂交水稻的抗性和米质等一些主要性状不适应现代农业生产和市场经济的要求;科技推广服务体系和科研人才培养机制不健全,缺乏相应的知识产权保护政策和科技成果转化机制等.因此利用现代分子育种新技术来扩大杂交水稻亲本间的遗传差异,利用杂种优势群组,精细育种等科学理论来指导热带地区杂交水稻的培育,并紧密加强公益机构和种业的合作,创建互补双赢的科研和商业化结合的机制,对于促进杂交水稻的可持续发展有重要的意义.另外,国际水稻研究所组织成立的全球杂交水稻协作网有望为热带杂交水稻的进一步发展提供帮助.
英文摘要: Increasing rice production has always been a top priority in Asian countries.The research and development of hybrid rice has contributed significantly to global food security since the 1970s. Inspired by Chinas success, many countries, specifically the South and South-East Asian countries, have started hybrid rice programs through introduction, adoption, and localization from the 1980s. Currently, about 20 million hectares of hybrid rice are being produced annually in the world, including 6.4 million hectares outside of China, mostly in the South and South-East Asian countries. The United States of America also became an important hybrid rice growing country since the 2000s. Different countries used various approaches and patterns of technology development and adoption. Planting areas of hybrid rice fluctuated yearly depending on technical adoption, seed supply, weather, and government policies. Adoption rates of hybrid rice in the major rice-producing countries are still low, which leaves great potential for further development. The main constraints for hybrid rice adoption in the tropics are low levels of hybrid heterosis, high price and lower quality of seeds, poor milling gain quality associated with high chalkiness and low head rice yield, low resistance to major pests, and poor education to farmers and unstable government policies. Recent progress of grain quality improvement made hybrid rice more acceptable by farmers and rice consumers. International Rice Research Institute has been playing a significant role in the development of tropical hybrid rice including extensive research, variety breeding and releasing, training and technology extension. Application of semi-dwarf rice varieties, so called the green revolution, has significantly increased rice production in Asia. Unfortunately, the common adaption of semi-dwarf germplasm originated from one sourcegermplasm homogenesismight have also contributed to the reduction of germplasm diversity which makes less hybrid vigor and could be one of the main causes for low yield heterosis compared to the hybrid rice in the temperate regions. The concept and practice of heterotic grouping used in hybrid corn have not been applied to hybrid rice development. Recent progress made from the association of public institutes and seed industry has been beneficial to both investors and will support for the sustainable growth of hybrid rice in the future. New challenges such as cultural practices, climate change, market demand, management of intellectual property, and the application of gene transformation technologies require a close collaboration among scientists, farmers, policy-makers, public institutes, and the seed industry.
