II Youhang 1, a space-bred super rice developed by XIE Hua'an, President of Fujian Provincial Academy of Agriculture Sciences, has produced a world record per mu(1mu=0.0667ha.) yield of 928.3 kg. The announcement was made at an on-the-scene verification check recently organized in Youxi County, Fujian Province.

II Youhang 1 is a combination hybrid, selected from three mutated space-bred rice species grown in different ecological areas, including Fuzhou, Shanghai, Hangzhou, Nanjing, and Sanya. The testing results, produced by the Rice and Related Products Quality Control Center, a part of the Ministry of Agriculture, show that the new hybrid combination characterizes a fine quality and high yield. Its five major indicators, including fine grain rate, whole grain rate, amylose, and protein, reach the top standards defined by the national criteria. Expert panel made an on-the-spot investigation of 101.1 mu of II Youhang 1, grown over a demonstration site in Mayang Village, Xicheng Township of Youxi County. Experts selected out 6 patches of typical fields for yield weighing. After drying and blowing, the per mu rice yield of these patches reached 928.3 kg.
