Academician Yuan Longping, an unparalleled master of Chinese studies, passed away. What effect will his death have?

The death of Mr Yuan Longping is a great loss to people all over the world. Mr. Yuan Longping fought for the grain industry all his life and advocated frugality all his life. Mr. Yuan Longping did only one thing in his life, which solved the problem of feeding people in China and brought hope to many people who are still starving in the world.

It can be said that Yuan Longping's ideal is simple and clear: "Let more people have enough to eat."

If you talk about being poor all your life, chinese odyssey, the national scholar.

Mr. Wang is really the pillar of the country, the hero of the nation and the hero of the people.

Great men are for the country and the people.

First, the father of hybrid rice in the world

"If you don't have millet, the country will die. If you have millet, you will die. If you have millet, you will not die." -"pipe"

After Yuan Longping made a world-leading breakthrough in the field of hybrid rice, instead of lying on the credit book, he insisted on going down to the fields and led his team to cultivate a variety of excellent rice.

The yield of new rice varieties cultivated in Yuan Longping has gone up to the sky, far exceeding that of ordinary rice. But we don't seem to have eaten Yuan Longping's meal at ordinary times. Why?

Because when Yuan Longping was young, China was always short of food, and people went hungry every year, even in difficult years. Therefore, all the breeding goals in Yuan Longping are to increase the yield, and the taste is not the scientific research goal pursued by Yuan Longping.

From 65438 to 0976, hybrid rice in Yuan Longping was popularized all over the country. 1988, half of the paddy fields in China were planted with rice from Yuan Longping.

At that time, hybrid rice greatly solved the problem of China people's eating, and made great contributions. But now the planting area of hybrid rice in Yuan Longping is less than 8.5%, and the number is seriously shrinking.

Why don't we plant hybrid rice from Yuan Longping?

Because after 1988, China's national strength gradually increased, and the problem of China people's eating was slowly solved. It is very rare that they can't eat, and China people begin to pursue eating well, not eating well.

The price of rice is very cheap, so you don't need a few dollars to eat it. Why not buy something delicious?

There are not many hybrid rice markets in China. But Yuan Longping still insists on pursuing higher rice yield, because he grew up hungry, and he doesn't want any China people to go hungry in the future.

Yuan Longping's team also developed sea rice, which can be planted in saline-alkali land with a maximum yield of 800 kg per mu.

Second, the main contribution

Yuan Longping took the lead in studying the utilization of rice heterosis in China. In his first paper, Rice Male Sterility, he proposed: "If you want to take advantage of rice heterosis, you must first take advantage of male sterility". His theory and research practice challenged the classical genetics theory, negated the traditional view that self-pollinated crops have no heterosis, and greatly enriched the theory and technology of crop genetics and breeding? . Yuan Longping solved three difficult problems in the research of three-line hybrid rice. Firstly, the technical scheme of "distant hybridization between wild rice and cultivated rice" was put forward, and finally an effective way to cultivate male sterile lines was found. 1973 realized the "three lines" of sterile line, maintainer line and restorer line. Second, a number of combinations such as "Nanyou No.2", a hybrid rice with strong advantages, were bred and widely used in production, becoming the first scientist in the world to successfully utilize the heterosis of rice. The third is to break through the seed production barrier. According to previous studies, the outcrossing rate of rice is only 2.4%, and the seed yield of hybrid generation is extremely low, which is far from meeting the production requirements. The International Rice Research Institute started research on 197 1 and gave up on 1973, because no one in the institute believed that it could solve the problem of seed production at that time. The research group led by Yuan Longping successfully solved this problem, and the seed yield gradually increased, reaching more than 300 kilograms per mu at present. Yuan Longping put forward the development strategy of hybrid rice breeding, that is, from three lines to two lines and then to one line, the procedure is getting simpler and simpler and the efficiency is getting higher and higher; At the level of heterosis, from varieties to subspecies to the utilization of distant heterosis, heterosis is getting stronger and stronger, which pushes hybrid rice to a new level step by step. This idea has been adopted by colleagues at home and abroad and has become the guiding ideology for developing hybrid rice breeding? . Yuan Longping solved some key technical problems in the dual-system method. For example, 1989, when the research of two-line method encountered great setbacks, he put forward the initial temperature index and technical strategy for breeding practical photo-thermo-sensitive genic male sterile lines, which made the research of two-line hybrid rice out of the trough. Later, the core seed production program and cold water series irrigation propagation were put forward, which made the research of two-line hybrid rice finally successful and popularized. Since 1987, he has served as a special responsibility expert for the "863" project and presided over the research on sexual cooperation in China. 1995 two-line hybrid rice was successfully studied, and the yield of two-line hybrid rice was 5% ~ 10% higher than that of three-line hybrid rice at the same maturity stage. Yuan Longping has designed the super-high yield plant type model with high canopy, short panicle layer and large panicle and the technical route of cultivating super hybrid rice, and has made great progress in the research of super hybrid rice. The research of super hybrid rice was carried out in Yuan Longping during 1997. In 2000, 2004 and 20 12, the targets of 700 kg, 800 kg and 900 kg per mu in the first, second and third phases of China Super Rice Demonstration Film were achieved respectively. In 20 13, the fourth phase of the research on the target of yield per mu 1000 kg of demonstration piece of super hybrid rice was started, and it is planned to achieve the target in 2020. At the same time, implement the high-yield project of "planting three crops and producing four crops" for super hybrid rice to promote the production and application of scientific and technological achievements. Since 2007, it has achieved great results in increasing production and income, and it has been implemented in seven provinces and cities across the country, among which the number of counties (cities and districts) in Hunan Province has increased from 20 to 50 in 20 12, covering an area of 8.82 million mu. By the end of 20 12, the accumulated demonstration and promotion area was more than 20 million mu, with an increase of more than 2 billion kilograms, making new contributions to the sustained and stable increase of grain production? . Third, summary.

In my opinion, the death of Mr. Yuan Longping is a great loss to the people and to the people all over the world. As for the impact on future grain production, it should not!

Why? There are two reasons:

First of all, Yuan Longping is a respected, talented and virtuous scientist. He has been engaged in scientific research and development all his life. He is modest and prudent, and is good at teaching and contributing his own scientific research achievements without reservation. This is his lofty and great personal quality;

Second, the scientific research team personally organized and led by Mr. Yuan Longping is completely mature and orderly, and both the scientific research strategy and the implementation of scientific research projects are running normally, smoothly and efficiently, which will not have a substantial impact on Mr. Yuan Longping's unfinished business in the future.

We wish Mr. Yuan Longping a pleasant journey! Let his old man rest assured that the scientific research team loyal to his great unfinished business and high prestige will certainly inherit Yuan Lao's legacy, continue to work hard, create more brilliant new scientific research achievements, and comfort his old man's soul in heaven!

Old Mr. Yuan Longping is immortal!
