Wheat Breeding Techniques and Methods

Team Name: Wheat Breeding Techniques and Methods Research Team

Research contents: exploring dwarf-male-sterile-wheat-based molecular population improvement techniques and resistance-identification efficient-screening techniques, and creating new wheat materials with  important target breeding traits such as stress tolerance, disease resistance, plant type, etc.; developing physical and chemical mutagenesis and high-throughput mutation screening techniques, building large-volume wheat mutant gene bank covering the whole genome, and creating a variety of new breeding materials; exploring the wheat-anther-based genotype disorder factor analysis and efficient regeneration techniques, building the high-frequency regenerative dynamic backbone parental clusters and engineering doubled haploid technical platform, and creating multi-resistant high-yielding new wheat varieties.

Research objectives: wheat population improvement, diversified induced mutation, engineering doubled haploid, and high-throughput stress-resistance identification and screening breeding techniques and methods, make new breakthroughs in wheat breeding material creation and application, cultivate high-yielding and multi-resistance new wheat varieties, and build an internationally competitive research and innovation team.

Team Chief Scientist: Professor LIU Lu-xiang

Professor Liu Luxiang, graduated from China Agricultural University and got the Master of Agronomy degree in July 1989, worked at the Atomic Energy Research Institute of CAAS in the same year, and served as deputy chief and then chief of Plant Breeding Research Group. He led the Group as a whole to join the newly established Institute of Crop Science of CAAS in 2003, and served successively as the chief of the Space Breeding Research Center, deputy director and then director of the Department of Genetic Breeding, and he is currently the director of Scientific Research Management Office of Institute of Crop Science, CAAS. In 2006, he was appointed chief scientist of national space breeding by the Ministry of Agriculture, and meanwhile he also served as the director of the National Crop Space Mutagenesis Techniques Improvement Center, deputy secretary general of China Society of Agricultural Biotechnology, secretary general of Crop Biotechnology Society under China Society of Agricultural Biotechnology, chairman of Radiation Genetics and Space Breeding Committee under Chinese Society of Nuclear Agricultural Sciences, member of State Manned Aerospace Applications Expert Panel, general coordinator of International Atomic Energy’s plant mutation breeding projects in Asia-Pacific regions, the general convener of Asia-Pacific Plant Mutation Research Network, editorial board member of Horticulture, Environment and Biotechnology, and deputy editor of Journal of Nuclear Agricultural Sciences.

He has been long engaged in identifying new factors leading to plant mutation and in nuclear radiation, space breeding and wheat cell engineering breeding research, and takes the charge of coordinating National Nuclear Radiation Mutation Breeding Network, National Space Breeding Network and the Asia-Pacific International Plant Mutation Research Network, and leads a number of projects funded by National Space Breeding Special Project, National Support Program, National 863 Program, National Natural Science Foundation of China, Agricultural Nonprofit Industry Special Research Projects, Bio-Breeding Special Projects and International Cooperation Projects, etc. He has developed crop aerospace mutagenesis, nuclear radiation mutagenesis target mutant directed screening technology and wheat vitro mutagenesis single-cell system breeding technological system, found new ways for mutagenesis improvement in ground-simulated space environment, created the new germplasm H307 and dynamic backbone parental clusters that raise wheat anther culture green plantlet yield to over 30%, created Jing 411 and Zhongmai 175 wheat cultivars mutation bank through mutagenesis, and approved 15 new varieties of wheat, maize, rice and vegetables. He wins 4 provincial and ministerial awards, gets 4 authorized patents, applies for 7 patents and 2 rights to protection of new varieties, publishes over 130 papers, participates in the compilation of 2 textbooks, hosts 4 international conferences /seminars and 1 national conference, and guides 27 postgraduate students including 8 still on campus.
