Dr Yunbi Xu, molecular maize breeder/senior scientist, the head of Applied Biotechnology Center, International Maize and Wheat Improvement Center), Mexico. Yunbi got all his education in China including B.S. from Huazhong (Central China) Agricultural College in agronomy in 1982, and MS (1985) and PhD (1993) from Zhejiang Agricultural University in genetics and plant breeding. Yunbi was an assistant and associate professor and the Deputy Director of Department of Agronomy, Zhejiang Agricultural University (1985 to 1995), the Rockefeller Foundation Postdoctoral Scientists at Cornell University (1995-1998), molecular breeder at RiceTec, Inc., Texas, for hybrid rice breeding (1998-2003), research associate scientist at Cornell University for genomics of water use efficiency in rice (2003-2006). Yunbi’s research fields are genetics and plant breeding including molecular marker development, germplasm evaluation, QTL mapping, marker-assisted selection, and molecular breeding, with focus on rice (1982-2006) and maize (2006-). His publications include over 90 referred journal articles, book chapters and conference papers, and two books (Molecular Quantitative Genetics, China Agriculture Press, 1994; Molecular Plant Breeding, CABI Publisher, 2009). He is an editor for three international journals (Theoretical and Applied Genetics, Molecular Breeding, and International Journal of Plant Genomics) and two Chinese journals (Acta Agronomica Sinica and Chinese Journal of Agricultural Science).
