The first production measurement exceeded 1000 kg
From October 21 to 22, Hunan agricultural society organized experts from Chinese Academy of Agricultural Sciences, Fujian Academy of Agricultural Sciences, China Rice Research Institute, Hunan Agricultural University, Hunan agricultural and rural department, Hunan Rice Research Institute and other units to visit the National Hybrid Rice Engineering Technology Research Center (Hunan Hybrid Rice Research Center) in Yunji Town, Hengnan County, Hunan Province The field investigation and yield measurement of the third generation hybrid late rice series combinations demonstrated in Yuhu District of Xiangtan City and Furong District of Changsha City were carried out.
In the machine harvest and yield measurement of the new combination g3-1s / parent 19 demonstrated in Yunji Town, Hengnan County, the first hill has a paid in area of 468.48 square meters and 882.8 kilograms of gross grain; The second hill has a paid in area of 711.52 square meters and a paid in gross grain of 1363.0 kg. Converted according to the standard water content of 13.5%, it is equivalent to 1034.4 kg and 1058.3 kg per mu respectively, with an average yield of 1046.3 kg per mu.
Yuan Longping said that the yield test results met the expectations. He was very satisfied and hoped that the variety would pass the examination and approval as soon as possible and be able to produce seeds in Hainan.
At the expert review meeting on field investigation and yield measurement of the third generation hybrid rice, the expert group believes that the new combination of the third generation hybrid late rice has strong performance advantages and has made a major breakthrough in yield. It is suggested that the state and relevant units give strong support to speed up the process of industrialization.
The next step will be a sprint to 1333 kg per mu
Yuan Longping said that according to the preliminary measurement, if the weather is good in the later stage, it may reach 1200 kg per mu.
At the expert review meeting on the investigation and yield measurement of the third generation hybrid rice, Yuan Longping introduced that the third generation hybrid rice is a new hybrid rice prepared by using ordinary Recessive Genic Male Sterile Lines as female parents and conventional varieties and lines as male parents. The third generation hybrid rice male sterile lines not only have the advantages of stable fertility of three-line method (the first generation) male sterile lines and free mating of two-line method (the second generation) male sterile lines, but also overcome the limitations of three-line method male sterile line mating and the risks of two-line method male sterile line reproduction and seed production. It is an ideal way to make use of rice heterosis.
"We will strive for the new combination Sanyou No. 1 (g3-1s / Pro 89) to pass the examination and approval of Hunan Province next year, and then promote it to the whole country to continuously expand the demonstration area." Yuan Longping said that in the future, his team will work towards the goal of producing 20 tons per hectare (i.e. 1333 kg per mu).

What is the difference between the third generation hybrid rice and the first two generations?
Overcome many shortcomings of the first two generations of Hybrid Rice
In an exclusive interview with the Beijing News reporter, Yang yaosong said that the first generation of hybrid rice is a three-line hybrid rice with cytoplasmic male sterile lines as genetic tools, the second generation is a two-line hybrid rice with light and temperature sensitive male sterile lines as genetic tools, and the third generation is a hybrid rice with genetic engineering male sterile lines as genetic tools.
In the research of the third generation hybrid rice, the genetically engineered male sterile line bred from common genic male sterile rice through genetic engineering has the advantages of stable fertility of three-line male sterile line and free combination of two-line male sterile line. At the same time, it overcomes the disadvantages of limited combination of three-line male sterile line and easy influence of light and temperature conditions on the fertility of two-line male sterile line.
In the experimental planting field, the reporter of the Beijing News saw that compared with ordinary rice, the rhizome of the third generation hybrid rice is obviously strong and much higher, and the highest rice can be chest high with adults. Multiple cameras are installed around the test field for real-time monitoring.
At the same time, the third generation hybrid rice also overcomes the shortcomings of the second generation hybrid rice which is sensitive to light and temperature, and the hybrid advantage is obvious.

What are the characteristics of seed research and development of the third generation hybrid rice?
Seed production and reproduction are very simple and easy
Yang yaosong said that hybrid rice is equivalent to fruit tree grafting. Generally speaking, it is equivalent to a hybrid, which has nothing to do with transgenic.
For the research and development of the third generation hybrid rice seeds, Yang yaosong introduced that genetically engineered hybrid rice belongs to the third generation hybrid rice. Genetic engineering male sterile lines produce about half pink seeds and half ordinary (yellow) seeds on each panicle. The yellow seeds are non transgenic and male sterile, which can be used for seed production, and the hybrid rice seeds are also non transgenic; Pink seeds are genetically modified and fertile and can be used for reproduction. The rice ears of their self bred offspring are half pink and half yellow seeds. The two are completely separated by color selection function. Therefore, seed production and reproduction are very simple and easy.

What is the prospect of mass production of the third generation hybrid rice?
Yuan Longping hopes to produce seeds in Hainan next year
Yuan Longping expressed the hope that the varieties tested for production will pass the examination and approval as soon as possible and can be produced in Hainan next year.
In 2011, Yuan Longping led the research and utilization of the third generation hybrid rice breeding technology, and obtained the hybrid rice breeding technology with genetically engineered male sterile lines as genetic tools.
By 2017, hybrid rice had been popularized in China for more than 9 billion mu, increasing production by more than 900 billion kg. Based on one kilogram of rice per person per day, hybrid rice can feed at least 5 billion more people for one year.

The third generation hybrid rice will be delicious
Yuan Longping previously told a Beijing News reporter that in the last century, we should solve the problem of food and clothing and let people eat first. Now everyone's living standards have improved. People are not only satisfied with eating, but also eat well.
"I thought there was a contradiction between high quality and high yield. In fact, there was no contradiction, but it was difficult." Yuan Longping said that last year in Qingdao, he gave the super rice jointly developed by his team to the vice president of the Japan rice association to taste. The other party said "good, good, you can talk to & lsquo; Over light & rsquo; 'ah'.
According to Yuan Longping, there is a rice variety called 'Yueguang' in Japan, which sells 80 yuan a kilogram in Beijing supermarkets, and the yield per mu of super rice developed by his team is much higher than that of 'Yueguang'. "& lsquo; Over light & rsquo; The real estate volume per mu is 800 kg, and our super rice is 800 kg. "
Secretary Yuan Longping and hybrid rice expert Yang yaosong introduced that they have already made strategic adjustments in hybrid rice research. Hybrid rice should not only have high yield, but also have high quality. For the taste of the third generation hybrid rice, Yang yaosong said it would also be delicious.
