Chinese scientists have set a new world record for per-hectare yield of hybrid rice, with a new variety producing 17,782.5 kg per hectare, 12 kg more than the previous world record of 17,770.5 kg.

The team of scientists, from Yunnan Agricultural University and Yunnan Provincial Academy of Agriculture, cultivated the Teyou 175 hybrid rice using nuclear radiation and biological methods. Professor Yang Rencui of Fujian Agricultural University, in east China, headed the team.

The rice was grown on demonstration farmland in Yunnan Province, southwest China, and the record yield verified by the Lijiang Prefecture Science and Technology Commission.
