The head of the super hybrid rice research and development team: Hybrid rice and transgenic technology are two completely different concepts. Xinhuanet Changsha September 26th “900 kg is just the number in the experimental field. There is no practical significance.” “The quality of super hybrid rice is not good. ""Super hybrid rice may contain genetically modified components." While screaming for a new record for super rice all over the country, the questioning of China's super rice has not been cut off.

In this regard, Yuan Longping and his team have always maintained a clear understanding. On the afternoon of the 24th, in the conference room on the first floor of the Hunan Hybrid Rice Research Center, Deng Qiyun, the head of the R&D team of the super hybrid rice “Y Liangyou 2” and Yuan Longping, told Xinhua News Agency that the hybrid rice was a natural hybrid to improve varieties. In the lab, through genetic manipulation, the integration of genes of a class of organisms into the genome of another class of organisms to perform a series of transgenic technologies is a completely different concept.

Deng Qiyun, 49 years old, said that the Hunan Hybrid Rice Research Center will receive visitors from all over the world every year. Each time Yuan Longping specially explained that he used super hybrid rice to cook for guests. According to many visitors, the difference between the quality and texture of hybrid rice and Thai rice is not significant.

Leifeng Village, Yanggu Township, has an altitude of more than 300 meters above sea level. Its ecological conditions and light are all relatively good. It has a long growing period and a lot of material accumulation. "Here, if the output exceeds 900kg, it does not mean that it can achieve the same results in large-scale promotion." Deng Qiyun said that even in accordance with the Ministry of Agriculture's third-phase goal of super rice, it is necessary to produce two consecutive years of production in the same ecological zone. Achieving 900 kilograms means the initial realization of the goal.

However, this does not mean reducing the realistic significance of the 900-kilogram target. It is understood that in 1980, Japan proposed a 15-year plan to increase production by 50% through hybrid production. In 1989, the International Rice Research Institute proposed a new plant breeding program that uses tropical indica rice to increase yields. However, it has not been realized so far. Area increase target.

“This time, the average yield per hectare in Longhui county is over 900 kg, which means that the research level of hybrid rice in China is far ahead in the world.” Deng Qiyun said, even according to Yuan Longping, large-scale promotion of production will have to hit 85. Discounts of 75% or even lower, but also to reach or close to the level of 700 kg per mu.

"Every progress in hybrid rice requires social inclusion and encouragement, but we also welcome all kinds of queries." Deng Qiyun said, "Because the challenge will prompt us to make greater progress."

September 18, 2011, Leifeng Village, Yanggu Township, Longhui County, Hunan Province. After the expert group appointed by the Ministry of Agriculture passed a rigorous inspection and acceptance procedure, a total of 107.9 mu of “Y Liangyou 2” with an average yield of 926.6 kg was obtained in 18 test plots. This is another peak in the world history of hybrid rice.

Deng Qiyun believes that the breakthrough of “Yliangyou 2” has once again proved the correctness of the technical line proposed by Yuan Longping. “The teacher said that the core technology of hybrid rice high yield is to combine morphology improvement and hybrid superiority.” Deng Qiyun An analogy that Yuan Longping had played was told to reporters. A good form is like Yao Ming's "good figure", and the advantage of hybridity is not to "puffiness," but to be physically strong.

However, it is not easy to let rice seedlings grow into ideal plant types but also group production. Deng Qiyun told reporters that the selection and cultivation of a variety of plants should be carried out in four to five years, and that they need to cooperate with each other.

In order to breed new super hybrid rice varieties, Deng Qiyun and his colleagues paid the hardships that ordinary people could not imagine. “When people are blowing air conditioners at home, we have to observe the flowering of the rice in the big sun. Even an umbrella can't be beaten. If you hit it, you can't see clearly.” Deng Qiyun said that many researchers on the team have been unable to communicate for several consecutive Spring Festivals. The reunion of the family, as well as the sun exposure, the rushing mountains and waters, is even more common for those who engage in rice.

"A lot of people don't understand why it's hard for us to engage in this line of business. I think there is always hope there will be waiting for you." Deng Qiyun said.
