He has been busy in the fields for decades. He is 90 years old and can speak fluent English at the seminar on China Africa agricultural cooperation and development. He has always had a dream of "enjoying the cool under the grass": in the experimental field, hybrid rice grows higher than sorghum, the ear is as long as a broom, and the grain is as big as peanuts. He hangs his head down heavily. A gust of wind blows, and the rice waves rise one after another. He lies under the rice ears to enjoy the cool… Who is the old man who has this idea? Yes, he is my most respected "father of hybrid rice" – grandfather Yuan Longping! He started with a dream and fought for it for most of his life.
Yuan Longping was associated with and accompanied with the peasants all his life, but he was not a child of ordinary peasant families. His father, yuan xinglie, graduated from National Southeast University, and his mother, Hua Jing, was a teacher in a missionary school. In Yuan Longping's childhood memory, no matter how turbulent the times were, his parents never gave up the opportunity for his brothers and sisters to study. But parents never thought that they would support their children to go to school. When they got to college, their children had to choose to study as farmers. Yuan Longping recalled: "in the first grade of primary school, I saw a beautiful horticultural farm during my outing. I really like it. I especially yearn for the beauty of the countryside and the joy of agriculture. With the growth of age, the desire becomes stronger and stronger, and learning to be a farmer becomes a life ambition. But my parents didn't agree. My father asked me to study medicine and science and engineering. My mother said it was hard to study as a farmer and I had to be a farmer. I argued with my mother about the importance of studying as a farmer, saying that we should also set up a horticultural farm and have pastoral fun in the future. " Parents finally respect their children's choices. Yuan Longping fulfilled his wish and entered the palace of agronomy. After studying genetics and breeding in the Department of agronomy of Southwest Agricultural University for four years, he felt heavy on his shoulders: "seeing the poverty and backwardness of the countryside at that time, I was a little ambitious, determined to transform the countryside and do something for the farmers. I think that's the duty of those who study as farmers. " www.iread.wang
On Commemorating Yuan Longping's grandfather's feelings
In the world at that time, the authoritative point of view in breeding circles was that there was no degeneration in self pollination, so there was no heterosis in hybridization. Yuan Longping doubted the authority and challenged it bravely. Later, recalling his mind at that time, Yuan Longping said: "I was an ordinary teacher of secondary agricultural school in Anjiang agricultural school. Many experts of the older generation thought that self pollinated rice had no heterosis, so I was under great pressure. But I have confidence in the Heterosis of rice. First of all, I found this in fact; Secondly, although it is said in the book that there is no heterosis in rice hybridization, I think there is something wrong with its theoretical basis – since heterosis is a universal law in the biological world, rice is no exception, and this kind of heterosis will certainly greatly increase the yield of rice. The general direction is correct. Through hard work, even if there are setbacks, we can not give up easily. Finally, we can reach the other side of the bright future. "
According to the natural hybrid rice, Yuan Longping believed that there must be a natural male sterile rice plant with degenerated stamens and no insemination, but normal pistils. If we want to cultivate hybrid rice artificially, we must first cultivate the seeds of this kind of male sterile rice. Therefore, Yuan Longping began to search for natural male sterile plants with the characteristics of non dehiscent anthers. He had breakfast in the morning and went to the field with a kettle and two steamed buns. He didn't return until about 4 p.m. June and July, the hottest time, is also the best time for rice to blossom and look for abnormal stamens. He walks in thousands of rice ears every day, looking for a needle in a haystack. It's very hot in the sun; Below, barefoot, in the water. Under the hard conditions, he suffered from a serious gastrointestinal disease. When he had a stomachache, he pressed the pain with one hand and opened the rice ears with the other hand. Day after day, there is no harvest, but Yuan Longping is always optimistic and looking forward to tomorrow. On the 14th day of the search, after observing 140000 Rice Panicles with a magnifying glass, the first male sterile plant was found from Dongting early indica rice varieties. In this way, Yuan Longping kept on experimenting and sorting. Eight years later, the seeds were finally prepared successfully.
Dr. swaminasen, director of the International Rice Research Institute and former Minister of agriculture of India, spoke highly of Mr. Yuan Longping as "the father of hybrid rice". His achievements are not only the pride of China, but also the pride of the world. His achievements have brought good news to mankind. " With the dream of decades ago, grandfather Yuan Longping finally achieved success. He irrigated "hybrid rice" with sweat and brought benefits to people all over the world. I praise his spirit of never forgetting his original intention and persistent pursuit!
Grandfather yuan's life let more people see the charm of science, let young people see another wonderful, do not need flow, do not need hype, and really affect the existence of the times, see from many of the most basic human needs can also create great. This is also the wealth left to our generation!
