China’s hybrid rice yield per mu has made a breakthrough, contributing Chinese wisdom to ensure global food security
CCTV 2020-11-03
Yuan Longping, an academic at the Chinese Academy of Engineering: Its main advantage is its large ears. Each large ear has 800 or 900 ears, averaging about 400. Average yield per mu is higher than existing high-yield hybrid rice …
CCTV News:“Food is paradise for people.” Today, at the third-generation hybrid rice test base in Hengnan, Hunan, after on-site production tests conducted by the Ministry of Agriculture and Rural Affairs, Academician Yuan Longping’s team exceeded the target of 1,500 kg of double season hybrid rice per mu. What is the concept of 1500 kg? What impact will this have on the bags of rice in our country?
On November 2, experts from the Ministry of Agriculture and Rural Affairs measured the average yield of late rice sown on the third generation hybrid rice base in Hengnan, Hunan, at 911.7 kg per mu. In addition, the average yield per mu of early rice harvested in the same plot this year was 619.06 kg. Adding the two seasons of late rice, the average yield per mu is more than 1530 kg, or 3.060 kg, breaking the predetermined target of 3000 kg and setting a new all-time record.
Yuan Longping, Academician of the Chinese Academy of Engineering:Very excited, more excited. It turned out to be 880 kg so I was very satisfied, now it is over 900 kg and I am very satisfied. Now we are going to further promote the varieties and experience to the entire province and the entire country, and we will make new contributions to the country’s grain production.
Obvious advantages, an average gain of more than 100 kg per mu
Compared with ordinary rice, what is special about third generation hybrid rice? Sanyou No.1 is an excellent variety of the third generation hybrid rice tested this time.In 2011, the team of academic Yuan Longping established a research group to start the research In 2017, trial planting in small areas was successful, and by the second half of this year, research and demonstration planting had been carried out in more than 50 experimental fields across the country.
Yuan Longping, academic of the Chinese Academy of Engineering:Its main advantage is its large ears. Each of its large ears has eight to nine hundred grains, with an average of about 400 grains. Average yield per mu is 10-20% higher than existing high-yield hybrid rice, representing an increase of more than 100 kg. . There are 250 million mu of hybrid rice in our country, and an increase of 100 kilograms per mu would be terrible, it could increase production by tens of billions and increase grain production to half of Hunan province.

The yield per mu of hybrid rice continues to make progress and is also contributing Chinese wisdom to ensuring global food security.
Rice is one of the main food crops in China, with a planting area of 450 million mu, which accounts for about 30% of the total grain area, and its production accounts for about 40% of the total grain production of China.
While we support ourselves, China’s experience is also helping to ensure global food security. In the 1990s, the Food and Agriculture Organization of the United Nations listed the promotion of hybrid rice as the preferred strategy to solve the problem of food shortages in developing countries, and Yuan Longping was hired as a consultant. principal. Today, hybrid rice has spread to more than 20 countries and regions around the world.
Yuan Longping, Academician of the Chinese Academy of Engineering:There are 150 million hectares of rice fields in the world, and if half of them, 75 million hectares of rice fields are planted with hybrid rice. By calculating an increase of two tons per hectare, you can increase the production of 150 million tons of grain, which can feed between 400 and 500 million more people.
