After coming to the institute, under the guidance of Chang Ruzhen, a famous soybean resource expert, she quickly entered the role and bravely shouldered the heavy burden. He has participated in the national key scientific and technological project "Breeding of Agricultural Germplasm Resources and Identification of Agronomic Traits", the major project of the National Natural Science Foundation "Broadening and Improving Soybean Germplasm in Northeast China" and the theoretical research on early-maturing summer soybean breeding in Huanghuai area. She is modest and prudent, learning from old experts with an open mind, working hard and studying hard, full of tenacious fighting spirit. It is said that there are no sundays and holidays in her schedule, and the fields, laboratories, offices and dormitories are her "four o'clock" trips. After three years' efforts, her professionalism, working ability and professional level stand out among peers, which impressed the experts in the same industry. 1992, promoted to associate researcher.
"Outside the Qingshan Building outside the mountain, heroes fight for the upper reaches, not proud of winning the upper reaches, and there are heroes ahead." This is the motto she often uses to motivate herself. In practice, she feels that there is still a considerable gap compared with her international counterparts. In order to March to the forefront of world science, she must constantly "recharge" herself. So, from 65438 to 0993, she left her daughter, who was only 2 years old, and went to the United States as a visiting scholar and postdoctoral researcher. Through contact with famous foreign experts and scholars and advanced experimental conditions abroad, she worked hard to study the advanced scientific knowledge and technical means of molecular biology and molecular genetics. 1998 After returning to China, she devoted herself to intense scientific research work before returning to her hometown to visit her parents who had been away for several years. When Qiu works, he often forgets the hard work and fatigue, and always feels that there are endless things to do. He has presided over the completion of national key projects in the Eighth Five-Year Plan and the Ninth Five-Year Plan, national 863, 973 and 948 projects, national intelligence introduction, national natural science foundation, international cooperation and other national-level projects and sub-projects 15. During the "Ninth Five-Year Plan" period, she organized more than ten scientific research units to screen out more than 200 germplasm with excellent single character from the newly sorted soybean variety resources; Completed the genetic analysis of 9 crop germplasm excellent characters; 30 improved and innovative germplasm were created, of which 6 were rated as Grade I, 1 1 were rated as Grade II and 5 were rated as Grade III in the post-evaluation of national excellent germplasm subsidies. These new germplasm have played an important role in soybean breeding and production in China.
Many things happen. The advanced molecular marker technology that she has been studying hard abroad has finally come in handy. She identified the PCR marker of soybean salt-tolerant gene and the RAPD marker of northeast soybean mosaic virus 3 resistant strain by BSA method. Among them, the method and application of obtaining PCR markers of soybean salt-tolerant genes have applied for national invention patents; The marker of SMV resistance gene has been transformed into SCAR marker, and the recombinant inbred line population has been located in F linkage group, which is different from Rsv 1 locus. The molecular markers of two important genes and SSR markers of soybean cyst nematode resistance gene were used to identify the resistance to mosaic virus disease, salt tolerance and soybean cyst nematode disease, and a number of resistant germplasm with genetic diversity were screened out, which laid a material foundation for the selection of hybrid parents for resistance breeding. Protein and SSR markers were used to select the foreground and background, which not only shortened the breeding cycle, but also cultivated near-isogenic lines with soybean lipoxygenase deficiency, creating conditions for high-quality soybean production.
You don't need to whip yourself. Facing the future, she feels that she has a long way to go. In order to make her research field catch up with the international frontier as soon as possible, she devoted herself to the National Tenth Five-Year Plan 863, the molecular marker-assisted breeding and polymerization breeding technology of soybean high-quality multi-resistance genes 973, the construction of soybean core germplasm, the national key scientific and technological projects, the creation of new soybean germplasm and the national basic work of soybean genotype identification.
