Xinhua news agency, Changsha, September 28 (reporter Zhou Mian and Chen Di) – on September 28, in Pingshan village, Lisu Township, Xinshan, Miyi County, Panzhihua City, Sichuan Province, the yield of the third generation hybrid rice “Sanyou 2” developed by Hunan Hybrid Rice Research Center reached 1085.99 kg per mu. This is the highest yield per unit area of the third generation hybrid rice so far</ p> < p > on the 28th, a yield measurement team composed of experts from the Chinese Academy of Sciences, Sichuan Agricultural University, Sichuan Academy of Agricultural Sciences and other units organized by the Sichuan Provincial Department of agriculture and rural areas collected three fields from the experimental field for harvesting, and finally measured 1085.99 kg per mu</ p>

In 2020, at the same place, “Sanyou 1” realized the double cropping yield of the third generation hybrid rice in the form of double cropping late rice, exceeding 1500 kg per mu. Li Xinxin, researcher of Hunan Hybrid Rice Research Center and host of the third generation hybrid rice project, introduced that this “Sanyou 2” is a “reference” in the form of one season medium rice</ p> < p > it is understood that “Sanyou 2” has trial planting demonstration sites in Guangdong, Guangxi, Hunan, Yunnan and other places, and Pingshan village is one of the demonstration sites with the best performance</ p>
