Genomic selection (GS) is a new molecular marker assisted-selection approach for genetic improvement of quantitative traits that using all available molecular markers across the wholegenome to estimate breeding values of genotypes. In recently, a great progress has been made on wheat genomic research, after the A genome and the D genome were sequenced in 2013, The International Wheat Genome Sequencing Consortium (IWGSC) provided a chromosome-based draft sequence of the hexaploid bread wheat (Triticum aestivum) genome in 2014, total 124201 gene loci have been have annotated, those resulted the genome sequence information available for wheat genetic research. In the area of molecular markers, large quantity of SSR, DArT and SNP markers were developed, made possible the use of genomic selection in common wheat. Our wheat genomic selection project was started 2 years ago, in those two years, a wheat660 SNP chips was developed, 3 training populations including more than 500 genotypes were constructed based on 2 years 2 locations field observations, the preliminary model for genomic selection was established. In this presentation, the progress of the project will be present.
