Abstract:

With the rapid development of genomics and biotechnology,the genetic improvement of radish has transformed from conventional breeding to the stages of molecular design breeding and intelligent breeding. This article systematically reviews the latest progress in the research of radish nuclear genome,pan-genome and cytoplasmic genome. Focusing on the main breeding objectives,the molecular basis related to formation and thickening of radish taproot,resistances to main diseases and abiotic stresses,quality,bolting and male sterility were discussed,and their applications in the field of molecular breeding were also discussed. Based on the genomic information and the molecular basis of traits,the theoretical framework of the“Precise and Intelligent Breeding”strategy is further proposed. Multi-omics data were integrated for comprehensive analysis to reveal the regulatory mechanism of complex traits. Strengthening the research on Speed breeding,establishing a precise and intelligent breeding technology system from the interaction of genotype-phenotype-environment to design breeding,which would provide theoretical and technical support for the collaborative genetic improvement of yield,resistance and quality of Brassicaceae vegetable crops including radish.

Key words: radish, genomics, molecular breeding, quality trait, genetic improvement
