WUXI, Jiangsu, June 20 (Xinhua) -- Yuan Longping, known as the "father of hybrid rice", said on Sunday that his team was working on a new version of high-yield hybrid rice and might complete it in 2012.Yuan, director of the National Hybrid Rice Engineering Technology Research Center and a faculty member of the Chinese Academy of Engineering, made the remarks at the World Expo's third theme forum, which opened on Sunday in Wuxi, in east China's Jiangsu Province.The new hybrid, the phase-III super hybrid rice, was expected to yield 13.5 tonnes of rice per hectare, Yuan said.The previous hybrid, the second-generation super hybrid, was released for commercial production in 2006, yielding 9 tonnes of rice per hectare, on averageRice is a major food crop that feeds more than half of the world's population, Yuan said.China is now planting 440 million mu (29 million hectares) of rice per year, with an average output capacity of 6.3 tonnes per hectare.Among the acreage, hybrid rice accounts for about 57 percent of the total, with an average output capacity of 7.2 tonnes per hectare."The average yield of hybrid rice is at least 20 percent more than that of inbred rice, feeding 70 million more people annually," Yuan said.China is faced with a challenging grain situation this summer because of strong rainfalls in the south during the summer harvest season. Other problems include droughts in northern grain production areas and lingering low temperatures in the south.According to the Ministry of Agriculture, China needs to maintain an annual grain output of 500 million tonnes to feed the nation's 1.3 billion people.China's summer grain output rose six years in a row to top 123.35 million tonnes in 2009, which was 2.6 million tonnes more than the previous year."Hybrid rice will play a key role in ensuring food security worldwide in the new century," Yuan said."If 50 percent of the world's rice paddies were planted with hybrids, rice production could be increased by another 150 million tonnes, and 400 to 500 million more people could be fed," he said.Yuan believes food security is "a war people can not afford to lose" ."The global economic downturn will always end, but food security is the problem we have to face every second," Yuan said.Statistics from the United Nations showed about 1 billion people were suffering from hunger and malnutrition and every six seconds saw a child dying of hunger or related diseases.With the theme "science & technology innovation and urban future", the two-day forum focuses on innovations in science and technology.The previous two theme forums of the World Expo centered on communications and cultural heritages.Yuan started working on hybrid rice in 1964."I often drive my car to go to rice paddies to do research," said the 80-year-old, "The only difference is that when I was young, I rode a bicycle or motorcycle ....you could attribute it to improving life."Hybrid rice has also been commercialized in other countries, including India, Vietnam, the Philippines, Bangladesh and the United States."For the benefits of the world' s people, we are well prepared to help other countries develop hybrid rice," he said.

MOSCOW, June 21 (Xinhua) -- China has played a role of great importance during the founding and development of G20, Russian presidential aide Arkady Dvorkovich said on Monday."Without China's participation, it would be much more difficult for the group to discuss or solve the developmental problems of world economy. Therefore, the participation of China, as well as some other emerging economies like Brazil and India, has become prominently significant," Dvorkovich commented after a news conference ahead of the upcoming G8 and G20 summit in Toronto, Canada.The presidential aide said the Chinese leaders' stance and viewpoints, proposed in the previous three G20 financial summit since November 2008, have helped stabilize the world economy as a whole.Dvorkovich noted that China's decision on further exchange rate reform was not outcome of external pressure.He said that any country, including Russia, China and the United States, could not allow their domestic policies to be ruled by external factors. The nations, however, should understand the common and mutual responsibilities in the global economic system.The delegates to the G20 summit will adjust their polices after consultations, but nobody will bend under pressure, he stressed.Dvorkovich said that several countries may voice concerns over China's exchange rate policies at the summits, but there will not be large-scale discussions over the Chinese currency.The People's Bank of China, China's central bank, announced on Saturday a decision to proceed further with the reform of the exchange rate regime to enhance the flexibility of the RMB's exchange rate.
