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.

YICHANG, July 28 (Xinhua) -- China's Three Gorges Dam was tested for the second time this month when the swiftest water flow of the year hurtled down the swollen Yangtze River on Wednesday morning.Flow rates as high as 56,000 cubic meters per second were recorded at the dam at 8 a.m. Wednesday, dam engineers said.The dam withstood the flow with a water discharge rate of 40,000 cubic meters per second, meaning 16,000 cubic meters of water per second accumulated in the reservoir behind the dam.The safety monitoring results of the dam during the second flood peak have met engineers' predictions to prove its ability to contain flood waters, said Cao Guangjing, chairman of the China Three Gorges Corporation.The water level in the reservoir had risen to 158 meters at 8 a.m.Wednesday, about 17 meters below its maximum capacity of 175 meters.Officials expect the water level to rise to 161.5 meters Friday, a spokesman with the Yangtze River hydrology bureau said Wednesday.Continuous downpours in recent weeks have raised water levels in the upper reaches of the Yangtze.Water flows on the river's upper reaches reached 70,000 cubic meters per second on July 20 -- the highest level since the dam was completed last year and 20,000 cubic meters more than the flow during the 1998 floods that killed 4,150 people.Ship traffic through the dam resumed last Thursday after the first peak flow passed. But shipping was halted again at 10 p.m. Tuesday as the second round of floodwaters approached.After shipping service was suspended, a road near the dam was opened for vehicles to transport goods and people across the dam.
