ROLE OF THE USDA REGIONAL GENOTYPING CENTERS

The concept of USDA Regional Genotyping Center was original proposed by Van Sanford et al. (2001) to meet growing need of marker-assisted selection for scab resistant cultivars. With strong support from cereal crop researchers, three USDA regional genotyping centers have been recently established in Manhattan, KS, Fargo, ND and Raleigh, NC, respectively. Their missions include developing high throughput molecular markers for Fusarium head blight and other agronomically important traits of cereal crops, screening breeding materials and germplasm with molecular markers for breeding programs to perform marker-assisted breeding, and providing training and technical consultations on marker analysis to breeders and other researchers. Screening of breeding materials for the major FHB resistance QTL on 3BS will be the first service provided by the Centers. Protocols for sample handling, marker analysis, data analysis and data delivery will be proposed. Scopes of research and service in the Genotyping Centers will be discussed. REFERENCE
