CCTV News, Changsha, Nov. 3 (Reporter Jiang Wenjing) According to the “News” report of China Voice of China Central Radio and Television, the experiment of new hybrid rice combination was carried out on the morning of November 2. third-generation in Hengnan County, Hunan Province. The average yield per mu of late rice measured in the demonstration base was 911.7 kg. In July this year, the average yield per mu of early rice was 619.06 kg. So far, the yield per mu of the third generation double season hybrid rice, developed by the team of the “father of hybrid rice” Yuan Longping, has successfully passed the 1,500 kg mark.
Previously, the hybrid rice researched by academic Yuan Longping and his scientific research team repeatedly broke the rice yield records and made a great contribution to ensuring China’s food safety. This time, the production measurement has once again achieved a historic breakthrough in rice yield. What kind of assistance will third generation hybrid rice bring to China’s grain production?
Around 8 am on November 2, the new third generation hybrid rice combining experiment and demonstration base in Hengnan County, Hunan Province welcomed the late rice production. In this experimental demonstration field, a scientific research team led by academic Yuan Longping planted and developed a new variety of third-generation hybrid rice, Sanyou No. 1.
In the rice fields, “Sanyou No. 1” grows well, tall and tall, with full ears and grains. This type of rice reportedly has an average of more than 300 grains per ear, which is twice the grains of late dual season rice ears.
Third generation hybrid rice is a new type of hybrid rice. Yuan Longping believes that third-generation hybrid rice technology is the key to breaking the “ceiling” of yield per mu. At present, the National Research Center for Hybrid Rice Engineering Technology has established a mature third-generation hybrid rice improvement technology system, selected a batch of sterile third-generation hybrid rice lines, and cultivated “Sanyou No. 1 ”and other strong and excellent combinations. . Li Jianwu, Director of the Cultivation Office of the Hunan Hybrid Rice Research Center, said that the third-generation hybrid rice overcomes the shortcomings of the first-generation hybrid rice combination that is not free, and also outperforms the production and reproduction of second generation hybrid rice seeds that are easily affected by external environmental conditions. It overcomes the main deficiencies of the previous two generations of hybrid rice and is a major improvement in improvement.
On the production test site, “Three Excellent One”, the highly anticipated “number one seed player” ushered in the “big test”. The team of experts selected three plots in the experimental demonstration field, and after a series of meticulous preparations, 3 fields began to be harvested simultaneously. Throughout the production test, academic Yuan Longping made a 5G video connection with the production test site at the Hunan Hybrid Rice Research Center in Changsha. After more than three hours of production tests, at 12:20 noon, the team of experts announced the results of the production tests on the spot.
Xie Huaan, head of the production measurement expert group and academic of the Chinese Academy of Sciences, said: “In accordance with the relevant requirements of the Ministry of Agriculture, we carry out accurate production in accordance with each link. Final yield calculation is calculated according to the unified procedures and formulas prescribed by the Ministry of Agriculture. According to the three According to the results of the Sanqiu field yield measurement (blocks) of the expert team, the arithmetic mean yield per mu of the Sanqiu field is 911.7 kg “.
According to the evaluation of the group of experts in performance measurement, the yield of the late rice variety “Sanyou No. 1” per mu is 911.7 kg. Prior to this, the yield per mu of early rice varieties grown on the same base was 619.06 kg. This means that the yield per mu of the double season has reached 1530.76 kg, reaching the goal of “1500 kg high yield”. This means that “Yuan Longping’s dream of enjoying the cold under the grass” is one step closer. Yuan Longping said cheerfully: “I am very excited! I am very satisfied when it reaches 880 kg. Now it weighs more than 900 kg. I am very satisfied. This is the result of everyone’s joint efforts. The 3000 jin was made for the first time. in Hunan, the hometown of hybrid rice, and even more. The icing on the cake. We will continue to promote the varieties and expertise throughout the province and country, and make new contributions to the country’s cereal production! “
Southern rice-producing areas this year were reportedly faced with extremely low temperatures and little sunlight, and third-generation hybrid rice varieties performed relatively stable and withstood the test. Guang Defu, chief agronomist at the Ministry of Agriculture and Rural Affairs, stated at the scene that the yield of double season hybrid rice exceeded 1,500 kg per mu, which clearly demonstrated the “genetic strength” of third generation hybrid rice, which has the characteristics of high performance, disease resistance, cold resistance and lodging resistance. . The achievement of the expected objective in the production tests is of great importance for national food security.
Guang Defu said that rice is the top three staple food crops. The successful removal of rice has increased the yield, ensured the quality, and promoted the development of high-quality agriculture, which is of great benefit in improving people’s quality of life. In particular, China has more people and less land, and the red line of 1.8 billion mu of arable land must be firmly maintained. How do we keep our jobs? Guangdefu pointed out that it is necessary to continuously improve quality and improve varieties. Now that the contribution rate of science and technology can reach 60%, we have technological progress, a good team of experts and good policies to support agricultural development.Return to Sohu to see more
