SHIJIAZHUANG, Oct 30 (Xinhua): Yuan Longping, the "father of hybrid rice," and his team have set a new world record in super hybrid rice output, the science and technology department of north China's Hebei Province said Monday.
The new world record was set in test fields in the city of Handan, which achieved an average yield of 1,203.36 kilograms of rice per mu (about 0.07 hectares) of farmland. The tested rice variety was Xiangliangyou 900.
Yuan, who developed the world's first hybrid rice in 1974, has set multiple world records in hybrid rice yield in previous years. In 2017, he achieved a yield of 1,149.02 kilograms of rice per mu with the same variety in the same test fields.
Since the beginning of 2016, Yuan's team has managed 42 hybrid rice test fields in 16 provincial regions across China, including Yunnan, Sichuan, Shaanxi, Guangdong, Chongqing and Hunan.
About 65 per cent of Chinese depend on rice as a staple food.
AP from Washington adds: The Trump administration has imposed restrictions on technology exports to a Chinese semiconductor maker, citing national security grounds amid a mounting tariff battle with Beijing.
The limits announced Monday reflected official concern Chinese competition might drive some American technology suppliers out of business and leave the United States without sources of components needed by the military.
The Commerce Department said the limits on sales to Fujian Jinhua Integrated Circuit Co. were needed to "limit its ability to threaten the supply chain" for the military. The company will face additional license requirements to obtain US technology.
Washington has raised duties on $250 billion of Chinese imports in an effort to pressure Beijing to roll back technology development plans some American officials worry might erode US industrial leadership.
