The third generation hybrid rice breeding line seed fluorescence detection and sorting instrument successfully completed the task
[ Instrument R&D of Instrument Network ] May 17-26, led by Researcher Liang Jingqiu and Assistant Researcher Cao Nailiang of Changchun Institute of Optoelectronics, a team of 9 members of the third generation hybrid rice breeding line seed fluorescence detection and sorting instrument, went to the country to cross The Rice Engineering Technology Research Center completed the sorting of about 600 kilograms of rice seeds, ensuring the sorting and planting of the third-generation hybrid rice seeds this year, and successfully completed the trial selection task of the sorting machine engineering prototype.
The instrument was developed by the National Hybrid Rice Engineering Technology Research Center and the State Key Laboratory of Applied Optics of the Changchun Institute of Optics, and was jointly developed by the team of Han Guangliang and Liu Peixun of the Image Department of the Institute. The research and development of equipment has been highly valued and supported by Academician Yuan Longping. During the trial selection, the equipment operated normally and the performance was stable, which was highly praised by the leaders of the National Hybrid Rice Engineering Technology Research Center.

Academician Yuan Longping is known as the “father of hybrid riceâ€. The latest third-generation hybrid rice is a two-line hybrid rice using genetically engineered sterile lines as a genetic tool, overcoming the difficulty of matching three-line hybrid rice and the two-line hybrid The weakness of rice fertility instability, the double-season late rice yields more than 1,000 kg per mu, is the development direction of hybrid rice. In the process of seed breeding of the third generation hybrid rice breeding line, the realization of 100% identification and sorting of fluorescent seeds to ensure that the seeds do not contain transgenic components is the core technical problem of the popularization and application of this variety. In order to overcome this problem and promote the third-generation hybrid rice in a large area, the National Hybrid Rice Engineering Technology Research Center and the Changchun Institute of Optoelectronics have joined forces, and the director Jia Ping led the team to sign academician Yuan Longping in Changsha on November 26, 2019. The development task of the "Second Generation Hybrid Rice Breeding Line Seed Fluorescence Detection and Sorting Apparatus".
The equipment is only 6 months from the signing of the contract to the completion of seed screening, and it is necessary to ensure 100% identification and sorting of fluorescent seeds. The development cycle is short, the technical difficulty is large, and the development period is in an epidemic period, which further increases the difficulty of equipment development. With the care and support of the leaders of the two sides, the research team worked together to overcome difficulties and overcome the impact of various adverse factors, ensuring the smooth completion of the equipment on schedule and ensuring the third generation of hybrid rice breeding lines and F1 seeds this year Sorting and planting. Since the seeds of the third generation hybrid rice need to be screened before planting to ensure that the fluorescent seeds are selected 100%, this equipment is the key instrument for the third-generation hybrid rice to be widely applied and has great application prospects and broad Market value. During the development of the equipment, leaders such as Jia Ping, Director of Changchun Institute of Optics, Assistant Director Li Dabing, Executive Deputy Director of State Key Laboratory of Applied Optics, Zheng Yuquan, and Deputy Director of Basic Scientific Research Department Xu Liang paid great attention to them and came to the laboratory to give their opinions and opinions. It is recommended to encourage everyone to make persistent efforts to continuously optimize the plan and contribute to the power of Changguang Institute for the promotion and application of the third generation hybrid rice.
Director Jia Ping visited the test site in person
Academician Yuan Longping has always been very concerned about the development of the sorter. During the trial selection of the equipment sorter prototype, he personally met the researchers of the Changchun Institute of Optoelectronics and gave a thumbs up and said happily, "This equipment is good." Academician Yuan Longping also appointed secretary Yang Yaosong to the prototype test site to understand the situation of the prototype test in real time, and highly appraised and praised the achievements of the prototype test. During the commissioning and trial selection of the sorter, Yu Yinghong, vice president of the Hunan Academy of Agricultural Sciences, and Yuan Dingyang and Li Xinqi, the leaders of the third generation hybrid rice research group of the State Key Laboratory of Hybrid Rice, came to the site to guide them. The technical personnel of the two sides exchanged and cooperated closely, obtained a large amount of test data, and organized two technical docking and seminars, which laid a solid foundation for the subsequent product development and promotion.
Dean Yu Yinghong organized a special seminar for technical personnel from both sides
Dean Yu Yinghong said that the application of good equipment is inseparable from the experiment, and it must be continuously optimized and oriented to productization. The Changguang Institute and the Hybrid Rice Research Center will continue to work together to make greater contributions to China's hybrid rice and to ensure my country's food security.
