Aiming at the problems of over concentration of citrus fruit maturity and fruit quality in China, with the help of biomics and molecular operation technology, I focus on analyzing the molecular regulatory network of citrus fruit development and maturity, and build a marker assisted breeding platform, so as to provide theoretical basis, candidate genes and breeding technology for citrus breeding at maturity and fruit quality improvement. The key contents include: 1) Research on the regulation of citrus fruit ripening: using numerous ripening bud mutants and biomics technologies of citrus, we will explore important pathways and key genes for regulating citrus fruit ripening, so as to provide genes and theoretical basis for the breeding of high-quality late maturing new citrus varieties; 2) Molecular marker assisted breeding: Utilize the accumulation of basic research, and use the natural population and hybrid population of citrus to develop high-density and important character related molecular markers, to build a scientific, efficient and practical marker platform to assist in the selection of citrus varieties at early development stage, and to improve the efficiency of conventional citrus breeding.
