Host: Prof. Heng Zhang

Venue: No.1 Meeting Room

Abstract:

Molecular breeding, a new field emerging in early 1990s based on plant genomics, molecular biology, molecular genetics, quantitative genetics and breeding, is applications of molecular marker, transgene, and gene editing technologies in traditional plant breeding. Molecular breeding technologies, innovating breeding methodologies and discovering/creating novel genetic variation, have been widely applied to commercial breeding programs of multi-national seed company giants since the discovery of SNPs and the advent of high throughput SNP genotyping technologies, and are the core competitive advantages of world seed company giants. In this talk, molecular breeding technologies seamlessly integrated into the entire workflow of traditional breeding process, including genetic diversity assessment of breeding materials, parental line selection and cross design of segregating breeding populations, marker-assisted selection (MAS) of major genes/QTL, marker-assisted recurrent selection (MARS), linkage drag elimination or minimization, marker-assisted backcross conversion (MABC), genome-wide selection (GWS) of polygenic traits, GWS-guided creation of heterotic hybrids, SNP marker-based assessment of genetic purity of advanced breeding lines and hybrid seeds, and DNA fingerprint-based protection of proprietary varieties or hybrids will be presented; the trend of molecular breeding technologies will be discussed.

The seminar will be delivered in Chinese.
