Yuan Longping, Father of Hybrid Rice, said at the 5th International Hybrid Rice Symposium held recently that the world's hybrid rice research has made new and important progress in the past five years. The success of the new generation of super hybrid rice will increase rice yield. The potential has been raised to a higher level.
In a variety of rice farming ecosystems, hybrid rice can increase yields and increase resource use efficiency, thereby significantly improving food security and increasing farmers' income. Over the past decades, hybrid rice technology has achieved remarkable results and is now rapidly developing and expanding in Asia and other regions. Especially in China, the cultivation and promotion of hybrid rice has greatly increased the yield and total rice production, and has created tremendous social and economic benefits. At present, the annual promotion area of ​​super hybrid rice has reached more than 2 million hectares; after the first and second phases of the super hybrid rice were achieved in 2000 and 2004, the third phase of the target of super hybrid rice has made significant progress so far. It is expected that it can be achieved on schedule.
Chairman of the conference, Academician Yuan Longping, stated that at this seminar, experts will focus on hybrid rice breeding methods and variety improvement, application of biotechnology in hybrid rice, hybrid rice seed production, hybrid rice physiology, high-yield cultivation and efficient resources. The use of hybrid rice quality improvement, the economy of hybrid rice, and the strengthening of cooperation between research institutes and private enterprises in various countries, etc., to review, exchange and discuss, and seek for strategies and approaches for the development of hybrid rice technology and production in the future.
According to reports, in recent years, the total area of ​​hybrid rice cultivation in the world has been nearly 20 million hectares. The area of ​​hybrid rice developed outside China has grown from 820,000 hectares in 2002 to 2.13 million hectares in 2007.
Liu Yanhua, vice minister of the Ministry of Science and Technology, said that the application of hybrid rice technology has continued to expand in foreign countries. Currently, more than 20 countries have studied, introduced and applied this technology. Hybrid rice plays an increasingly important role in increasing world rice production and safeguarding international food security.
Dr. Fan Guyan, FAO representative, said that hybrid rice is very meaningful and influential in the world. There are also many coalition organizations in the world. The promotion of hybrid rice can increase global food production and improve the food crisis.
More than 450 experts, scholars and business people from 27 countries and international institutions including China, the United States, India, Indonesia, Bangladesh, Egypt, the Philippines and Vietnam participated in the conference.
