Admission time: May 2004

Academy: senior agronomist at the Institute of Vegetable Research Institute of Wuhan Academy of Agricultural Sciences

Honor: China Agricultural Science and Technology Award Excellent Innovation Team Award

Members of "Aquatic Vegetable Resources and Breeding Innovation Team of Wuhan Academy of Agricultural Sciences"

Yangtze Daily Da Wuhan Client News Before the Mid -Autumn Festival, in the national aquatic vegetable germplasm resource garden in Jiangxia District, lotus flowers are blooming. Various aquatic vegetables such as lotus roots, lotus puffs, diamonds, chicken heads, Cigu, etc. Mature and full can start digging, and some are mature. Dr. Liu Zheng collected seeds and was ready to continue breeding experiments in the laboratory.

"You see these dumplings that have been dug are our" August Fan ". As the name suggests, it has changed its powder in August. In the past, our pink bun generally had to be available until the National Day. , Wuhan people can drink a bowl of glutinous ribs soup in the Mid -Autumn Festival. "Liu Zheng pointed at a large lotus root to tell the reporter from the Yangtze River Daily.

In 2012, Liu Zhengzhi graduated from the Ph.D. from Huazhong Agricultural University and entered the Wuhan Academy of Agricultural Sciences. He joined the well -known lotus root breeding expert in my country, Ke Weidong's scientific research and innovation team to carry out lotus root breeding.

Each year, the team selects no less than 500 single plants to compare, and then select dozens of hybrid combinations for trial seedlings: first plant in the tank, if the variety performs well, then plant it into the national aquatic vegetable species resource garden 6 square meters 6 square meters In the small pond of rice. After the spring species, in the hot summer, Liu Zheng has to observe the growth of the species and make a record. Beginning in June, various varieties such as precocious precocious, medium, and late maturity have begun to harvest one after another. He must assist the workers to work and ensure the integrity of research, and they cannot relax in one step. After harvesting, Liu Zhengzhi continued to test his trait in the laboratory and further select the variety of excellent traits. For the well -performed varieties in Xiaochi, it will be planted to 66 square meters of large ponds. After 1-2 years, it will be compared and then decides whether to promote it. A high -quality variety often takes 8-10 years from experiment to promotion.

Breeding found demand from the market, then cultivated in the laboratory (field), and finally returned to the market for verification. "We cultivate 'August Fan" is because the market generally reflects the pink lambs' in recent years. Breeding staff also found that traditional powder varieties such as "Hubei No. 5" will only change after October. Fan. So we need to prefer the characteristics of 'powder' in breeding and continue to improve it early. At present, 'August Fan "Lotus Root is the first precocious pink lotus root in my country, rewriting my country's August without powder ravioli. History. "Liu Zheng said.

As the "Fourteenth Five -Year Plan" national characteristic vegetable industry technical system, the scientist of the scientist and the host of the national key R & D plan sub -project host of the Ministry of Science and Technology, Liu Zhengzhi also participated in the selection of "Hubei No. 9", "Hubei Lotus 1 1 The number ", which increases the yield of 10%to 15%over the main push variety, is currently the highest output in my country. The" White Jade Puppet No. 1 "that he participated in the selection is the first high -yielded lotus cricket in my country.

In addition to the selection of lotus root, Liu Zheng is still conducting molecular breeding research. After ten years of science and technology research, he first clarified the origin, evolution and domestication process, discovered more than 400 domestic -related genes, and successfully located the traits such as lotus color, flowering, and granularity, and developed more than 10 molecular marks.

"Everyone knows that Academician Yuan Longping discovered the problem of hybrid rice in the rice fields in the rice field. It is forward -looking and can shorten the conventional breeding time. The molecular label is to give breeding 'auxiliary' and find the genes you need. "Liu Zheng explained.

"Scientific research is to overcome the difficulties, and finally choose a variety with high yield, low planting costs, and high market popularity. For example, for the problem of pink coriander varieties often enter the mud depth. Related to 'into the mud depth', find the genetic sites of 'shallow' and 'fan', develop this molecular mark, choose breed and pink and dig varieties. Scientific research is endless. Maybe we can breed through molecular breeding in the future. , Cultivate a variety of benefits of the above lotus seeds and growing up below! "Liu Zhengzhi said," The history of the lotus has a history of 200 million years. Through the hands of our new generation of scientific researchers, creatures bloom in the new era. "
