An exhibition of wheat elite genetic resources held by Institute of Germplasm and Biotechnology
To promote the share of germplasm and to accelerate the development and utilization of wheat elite genetic resources, the Institute of Germplasm and Biotechnology held an “exhibition of wheat elite germplasm resources” at Experiment Station for Animal Science (JAAS) on May 18th. More than 70 participants attended the exhibition including leaders and experts from all across the country including Chinese Academy of Agricultural Sciences, Jiangsu Agricultural Committee, Nanjing Agricultural University, the University of Yangzhou, and Zhejiang Academy of Agricultural Science, etc. Related personnel from wheat breeding companies were also invited to the meeting. Wang Gang, Deputy Secretary of Party Committee of JAAS, attended the meeting and inspected the wheat germplasm nursery. Zhao Han, Director of the institute, chaired the meeting.
Wu Jizhong, research professor from the Institute of Germplasm and Biotechnology, introduced in details about the progresses of the collection, evaluation, pre-breeding, and utilization of wheat elite germplasms made by his research group in recent years. He also showed participants various wheat germplasm in “precisely phenotyping” nursery, introduction nursery, regeneration nursery, and FHB evaluation nursery. According to the introduction, since “the Thirteenth Five-year Plan”, funded by National Key R & D Program, National Germplasm Conservation Project, Jiangsu Agriculture Science and Technology Innovation Fund, etc. They identified many elite germplasm with disease or stress resistance. Some germplasm have not been fully utilized in breeding programs, such as “Ruanganyangmai” with highly resistance to Fusarium head blight (FHB), “Hongyoumai” with highly resistance to powdery mildew, and “IDO580” with extremely low Polyphenol Oxidase (PPO) activity. They developed new germplasm, such as “Ningmaizi 119” resistant to FHB, “Ningmaizi 126” with low PPO. They also showed two new elite lines “Ningmaizi 14213” and “Ningmaizi 15318” which are under national and provincial test now.
The diverse genetic resources not only provide materials for wheat genetic researches, but also provide the base of conventional & molecular wheat breeding. This exhibition offered a great communication platform for the research institutes and breeding companies. This meeting not only promoted the share and utilization of elite wheat germplasm, but also ensured the new needs of wheat breeding and industrialization. The exhibition is well recognized by the participants.
