On the road of scientific research | Min Donghong: The seeds of heart are willing to be breeders

As the first agricultural high -tech industry demonstration zone in my country, Yang Ling's team of Academician Zhao Hongzhang, who "saved most of the New China in a wheat variety" to the team of Academician Li Zhensheng, who won the National Supreme Technology Award; The team of researchers went to the team of Professor Wang Hui, and then the breeding expert Professor Ji Wanquan's team ... The generation of Yang Ling agricultural scientists took root in Yang Ling, and made outstanding contributions to my country's grain safety and modern agricultural development and the creation of a new global seed industry.

In the trial farm of Yangling Caoxinzhuang, Shaanxi, Min Donghong, a wheat breeding expert, often wore a grass hat, squatted in the wheat field, and used the "brute force" to pull the ripe wheat ears. Here the test demonstrates more than 170 new wheat products.

"It must be pulled up, not mechanically harvested, and it is fast, and it can't be delayed." Driven by him, the students also worked hot.

Min Donghong graduated from the Department of Agriculture, the former Northwest Agricultural University in 1990. In 1994, he joined the Zhao Hongzhang's wheat breeding team and engaged in the scientific research of wheat genetic breeding under the guidance of Professor Song Zhemin. In 1997, Professor Wang Hui, a wheat breedinger, has continued to work in the research of wheat genetic breeding. In addition to long -term engaging in conventional wheat genetic breeding work, the research on anti -reversal gene wheat molecular breeding was also carried out during the "Thirteenth Five -Year Plan" period. He has won 1 National Science and Technology Progress Progress 1 (secondary certificate), 1 second prize (second completed), and 1 first prize of scientific and technological progress in Shaanxi Province.

The teacher encouraged and introduced the door of scientific research

Entering the Mindong Red Office, there are a few "tied" golden wheat plants beside the desk. "Xian 598" "Xian Nong 625".

"These are the results of the continuous innovation of our scientific research team." Min Donghong picked up a bundle of specimens told reporters that as a breeder, he deeply felt that only variety innovation can make Tibetan grain in the reality and promote the seed industry can the seed industry be promoted Development makes a harvest of food. Breakthroughs in wheat varieties innovation and breeding methods have also allowed Yang Ling to be at the forefront of the country in ensuring food safety.

Looking back at the scientific research work process for nearly 30 years, failure and success, frustration and joy coexist, sweet and sour and salty, Min Donghong has deep feelings. In early 1994, he tasted the breeding of wheat breeding. Min Dong's red waist was sore and hurt. Watching the bright leather shoes turned into mud shoes. The previous expectations of work and the actual gap in work began to shake his thoughts, and his emotions permeated his body and mind.

"If it wasn't for Teacher Song Zhemin to talk to me, maybe I would like to do so with breeding scientific research. He encouraged me: To do a good job of scientific research, we must first have the spirit of hard work and hard work. We must overcome the current fear of fear. "At this point, Min Donghong" changed his head ".

In 1997, Min Donghong ushered in the first joy of breeding career: "Xian Nong 8727" Wheat -winning varieties were approved by Shaanxi Province, and in 2000 won the third prize of scientific and technological progress in Shaanxi Province. "This joy is inseparable from the guidance and encouragement of the teacher. "

If the original intention is not changed, it can be fully harvested in the end

In addition to the "Eun Hui" of Song Zhemin, Min Donghong, he was fortunate to follow Teacher Wang Hui to continue wheat genetic breeding. Min Donghong said back to the breeding process. Although it was hard, he was full.

With the approval of a number of provincial trial varieties such as "Xian 2611", "Xian Nong 9871", "Xian Nong 9872", "Xian Nong 822", "Xian Nong 165", it has strengthened Min Donghong's original intention. In 2003, "Xian Nong 2208" passed the national trial, the "Xian Nong 979" passed the national trial in 2005, and the "Xian Nong 9718" passed the national audit in 2006. Teacher Min's team has been reviewing three national trials for four consecutive years. Min Donghong said that whether it is his own host or participation in breeding, he has doubled his confidence, because this has achieved a breakthrough in the Wheat Breeding Research Office and the former Northwest Agricultural University for more than ten years.

"Although the variety passed the national trial, if it does not play its production and income increase in production as soon as possible, it is like writing on paper, sticking to the wall, and hanging on the showcase."

Therefore, in the future, Min Donghong will continue to promote the variety as an important job as his important work. The quality of the seeds determines the output and quality of grain, and the innovation of varieties determines the development of the seed industry. The successful selection of a new wheat variety for conventional breeding technology often takes 10 years or more. Min Donghong does more than 400-500 hybrids each year, but in the end, the combination that can be cultivated into a variety is one or two, or even one.

"Although the breeding work is very difficult, it must be persisted for years, otherwise all the previous efforts are futile." Min Donghong said.

Scientific research innovation, breeding again new merits

Although he has achieved remarkable results in the genetic breeding of wheat and won national awards, Min Donghong did not stay on the "Cultural Book", but continued to think about new breeding strategies and breeding methods.

Since 2019, Min Donghong has sought new ways in breeding technology and methods. "We adopted corn -induced wheat monocular body channels to carry out the research on wheat double -twice sports technology. At present, it has achieved staged results."

"Breeding must adjust the research direction in a timely manner in combination with the actual production and market demand. This is very important." Min Donghong said that in recent years, he and the team have adjusted in the direction of the selection of new varieties. On the top, quality improvement is used as an important breeding goal.

"Through the exploration of the past three years, we have mastered the preliminary dual monocial wheat breeding technology system. Using this technical system, it can be cultivated in four years. Breeding efficiency. "

At present, the Mindong Red Team has cultivated two new dual -twice wheat products (DH1959, DH1975). Its high yield, disease resistance and quality have performed well. Essence

"The charm of wheat breeding is the breakthrough from '0' to '1'. It has never been there. This is innovation, and this is the speed from '1' to '10'. These two must be grasped."

Min Donghong said that do not be afraid of suffering and tiredness in scientific research, but also can withstand sarcasm and even white eyes. Don't be afraid that others will say that you are new, but you must step on it and stick to it. If you dare not think, dare not do it, you can only follow others. Only by daring to dare to persist can we be the best in scientific and technological innovation.

The husband and wife are concentric, and the team is born "twins"

"Thank you for my lover, Associate Professor Zhang Xiaohong, the Teaching and Research Office of the School of Life Sciences, is also a member of our team. For many years, I have been silently supporting my work." He said that because of the understanding and support of his lover, he can only be able to whole body. Heart is invested in scientific research and breeding. At present, the team has been cultivated in three types of national trials (Xian 629, Xian 625 and Xian Nong 598), and 3 provincial trials (Xian Nong 059, Xian 619 and Xian Nong 627).

It is worth mentioning that "Xian 625" and "Xian Nong 598" were approved in the same year. The couple and their wives were one by one, refreshing the records of the same research team in the same research group in the Northwest Agricultural and Forestry University of Agriculture and Forestry Science and Technology at the same time. The "wheat twins" born as "husband and wife shop".

Accelerate the innovation of the seed industry, strengthen the "chip" of agriculture, and focus on creating the "Silicon Valley" in China's dry areas. This is Yang Ling's unremitting pursuit.

Min Donghong said that Yangling Wheat Breeding Scientific Research has a strong research foundation for a long time. Breeding levels and technology have been in the national advanced ranks. With the continuous improvement of molecular breeding technology and the combination of gene editing technology and conventional breeding technologies, Yang Ling wheat breeding scientific research will obtain rapid progress The development of breeding technology will be cracked.

For more than two decades, the team of Min Donghong has undertaken the National 863 Plan, the major special project cultivation of the national transgenic biological species, and the major science and technology projects of 13115 in Shaanxi Province, and more than 60 national and provincial and ministerial -level scientific research projects (projects) such as Shaanxi Province science and technology overall innovation projects (projects). , Nursery National Trial of 11 wheat varieties, 24 provincial -reviewed wheat varieties, and the cumulative promotion area of ​​breeding varieties exceeds 250 million mu.

Among them, Xunnong 979 wheat varieties, which won the second prize of the National Science and Technology Progress Award, have a cumulative planting area of ​​153 million mu by 2021, 54.412 billion kilograms of wheat production, and increased economic benefits of 21.826 billion yuan, which has made important contributions to national food security.

"After four years, I will 'get to the station'. Although the body can retire, the spirit of wheat breeding scientific research will never be retired, the agricultural sentiment will never be lost, and the development of the discipline will never slow down."

"My wish is to do a good job in the gang of wheat breeding scientific research in a limited time. Breeding and educating people can catch them together. Even if I can't be on the front line in the future, I must be a young man's cheerleading team to make Yang Ling's agricultural scientific and technological innovation. Develop the flag and shout! "

Life is endless, "chasing dreams" is more than. Innovative wheat scientific research and breeding, Min Donghong has been working hard.
