OVERVIEW OF GENOMICS-ASSISTED BREEDING OF COMMON BEAN FOR RESISTANCE TO COMMON BACTERIAL BLIGHT (CBB) AT GPCRC, AAFC

摘要

Progresses on structural and functional genomics of bean {Phaseolus, vulgaris L.) have provided bean breeders with novel and efficient tools in marker-assisted selection (MAS) for variety development. The availability of bean genome sequence and single nucleotide polymorphism (SNP) markers has changed the traditional MAS practice. The molecular biology and genomics laboratory at the AAFC-GPCRC and the bean breeding program at AAFC/Guelph in collaboration with researchers from USDA and South Africa have adapted the novel genomics approaches in developing co-dominant candidate gene markers associated with CBB resistance through sequencing, and in adapting association mapping method to integrate the two processes, namely CBB resistance QTL (quantitative trait loci) mapping and the CBB resistance variety development, into one process.
