Super hybrid rice output in test fields in southwestern Yunnan Province has set a new world record, local authorities said Monday.
超级杂交水稻云南试验田的产量创新世界记录。
The latest output of three plots at a super hybrid rice demonstration base located in Datun Township in the city of Gejiu reached an average of 1,152.3 kg per mu (about 0.07 hectares).
The demonstration base started to plant hybrid rice in 2009.
A group of experts from agricultural and scientific universities and research institutions randomly selected three plots on the rice fields and supervised the harvest.
With an average temperature of 20 degrees Celsius, the base lies at an altitude of more than 1,200 meters above sea level. Proper annual precipitation and flat terrain also contribute to the harvest of hybrid rice, according to Xie Hua'an, leader of the research team.
