Xiangxi is known as the "Cecum of China". Yuan Longping passed through this appendix and entered another world, a world he still knew nothing about. This is the starting point for China's hybrid rice to enter the world. It is also the birthplace of the earliest rice culture of the Chinese nation and the birthplace of world rice farming civilization - Anjiang. He has been coaching here for 18 years and his family has lived here for 37 years.
Here, Yuan Longping spent the first three years of confusion. When the spring wind of science finally blows to Anjiang, he hopes to develop some new varieties, a new crop with high yield. What exactly is this new crop he guessed? He is still a lost lamb.
But Yuan Longping knew clearly: Science must be tested through experiments. So he started his first experiment: grafting sweet potatoes and moonflower . As a result, he succeeded, and the sweet potatoes grew large and had high starch content.
But when he planted the grafted sweet potatoes as seeds, the situation was as follows: moonflowers bloomed above the ground, but no sweet potatoes grew underground. The conclusion is that asexual crosses cannot produce mutated seeds.
Russian Jewish pathologist Mechnikov said: "With the help of science, human beings can correct defects in nature." Yuan Longping did use science to test and prove the theory of the outstanding Soviet horticulturist Michurin in three years. fatal flaw. He went from confused and lost to suddenly enlightened, and finally returned to the starting point and started again.
In 1960, Yuan Longping turned his attention from sweet potatoes to rice. This was undoubtedly the most critical and decisive choice in his life. In the years to come, he will settle down in the rice fields, his soul is in the rice fields, and his world is in the rice fields.
He has clearly moved in one direction, the " Goldbach Conjecture " in the field of agricultural science - hybrid rice. The key to hybrid rice is to find the female parent.
Yuan Longping just put down his lesson plans and went straight to the rice fields. With a magnifying glass in one hand and tweezers in the other, go to the rice fields to observe and search for seeds. The sun on your head makes it very hot; your feet step on the paddy field and it feels very cold. You are truly in dire straits.
The hard work pays off in the end. In a magical moment, Yuan Longping discovered the first miraculous rice plant in his life - "Heli Jiqun". He carefully observed this extraordinary rice plant: it had an excellent plant shape, more than a dozen eight-inch-long rice, with large ears and many grains, and each grain was exceptionally strong and plump. He was as if he had found a treasure.
Finally in the spring of the second year, the seeds of "Standing Out among the Chickens" were planted in the experimental field. Yuan Longping, like his father who hopes his children will become successful, expected those seeds to grow into the next generation with strong plants and large ears and grains. I really hope that I will be disappointed as much as I want, but the result is that "the son is not as good as the father" is uneven, and a ladle of cold water was poured down.
This ladle of cold water woke up Yuan Longping. Through repeated statistical calculations on these plants, he finally concluded that "Standing Out of the Crowd" is a natural hybrid rice. He was extremely excited about this. After
, Yuan Longping went to Beijing to consult experts and solved the theoretical problems. The next step was to find the male sterile strain. But the chance of finding a naturally male sterile strain is almost slim.
Perhaps as Mencius said: "When heaven is about to assign a great responsibility to this people, they must first suffer their minds, work their muscles and bones, starve their skin, and deplete their body." On the first day since the beginning of summer in July 1964. On the 14th day, that is, at 2:25 in the afternoon on July 5, Yuan Longping's eyes once again exuded excitement and strange light. He finally found a female rice with a single sexual function that could be used as a hybrid mother.
After that, he and his assistants found six male sterile plants with different shapes among hundreds of thousands of rice ears. They are the life code of hybrid rice. Yuan Longping excitedly and clearly outlined the first blueprint for hybrid rice in China.
However, in order for a hybrid rice seed to go from the experimental field to the farmer's field, it has to pass three levels: the three-line matching level, the advantage combination level and the seed production level.
These three levels have not yet begun, but the "Cultural Revolution" has begun.More than 60 pots and jars where Yuan Longping raised seedlings were smashed, broken and torn seedlings were scattered all over the ground, and they were almost dried up by the scorching sun. How could he bear it? This was his lifeblood.
is pretty clear. Two of Yuan Longping's students, Li Bihu and Yin Huaqi, stole three pots and hid them before the seedlings were smashed. The experiment can continue again. Yuan Longping also went from almost being disciplined to being protected. At the same time, a landmark event in the history of China's hybrid rice development also occurred: China's first hybrid rice research group was officially established.
After repeated breeding, the three pots of rice seedlings had developed into two experimental fields by the spring of 1968. In order to speed up the pace of breeding, Yuan Longping decided to chase the sun and go to large natural greenhouses with high photosynthetic potential such as Lingnan, Hainan and Yunnan for breeding.
Afterwards, they carefully returned to the Anjiang Basin with more than 700 seedlings cultivated from Hainan. Yuan Longping cared for the seedlings in the ground like a baby. When the seedlings were about to blossom, fill, and ear, something desperate happened to him.
On the morning of May 18, 1968, the heavy rain began to clear up. When Yuan Longping walked through a green field, he was shocked by the sight before him: the seedlings in the field disappeared, and the experimental field turned into a muddy pond.
is simply a shocking blow. It was not until the fourth day after the incident that he finally found a few floating seedlings in a well. These five trees are the most tenacious lives and a contribution to the continuation of the experiment. They saved Yuan Longping's five years of hard work.
Yuan Longping and his team are like scientific pilgrims, traveling thousands of miles to their holy cities of Canada: Lingnan, Hainan, and Yunnan. He used more than 1,000 varieties, conducted more than 3,000 hybridization experiments and tens of thousands of tests, and gained a deeper understanding of "three-line" inheritance.
No matter at that time or now, on the road of scientific research and exploration, it is impossible to escape the fate of "winners, princes, losers and bandits". Yuan Longping also bears pressure from society, not scientific pressure. Fortunately, the Hunan Provincial Party Committee gave Yuan Longping the huge power to help Yuan Longping in times of need. He also told himself: Even if he spends his whole life, he must make hybrid rice!
Yuan Longping also decisively thought and chose to "find a breakthrough from wild rice that is more distantly related to than " and search for and collect wild rice resources.
November 23, 1970, is another day that will go down in history. Yuan Longping's assistant Feng Keshan found his mysterious lover "Ye Bai" in the wild rice fields beside the old railway. After experiments, the " three-system method " blueprint outlined by Yuan Longping was finally completed.
With overcoming difficulties one after another, China has finally entered the era of hybrid rice and has become the first country in the world to successfully utilize the hybrid advantages of rice on the production line. Yuan Longping is well-deserved as the "first person in hybrid rice in China". He accomplished something that no one in the world has accomplished, and hybrid rice became China's fifth greatest invention.
In October 1985, Yuan Longping received the gold medal and certificate of honor for the "Outstanding Invention Award" issued by the World Intellectual Property Organization wipo. This was the first time he won an international award.
The road to science is winding and long. On this rugged scientific road, Yuan Longping and his team have crossed one height after another, achieved leap after leap, and told the world with iron-clad facts: China's food is safe! Chinese people can feed Chinese people! The rice bowl of the Chinese people is firmly in the hands of the Chinese people!
