Rice genomic breeding chips with various SNP (single nucleotide polymorphism) densities are powerful tools for new variety development, which integrated a large number of representative molecular markers selected from massive rice genome sequences, key functional genes, and the most advanced SNP array technology in the world. The utilization tests of the chips demonstrated their important roles in genetic diversity analysis of germplasm resources, target gene identification, genetic mapping, breeding line screening for an ideal genotype, variety fingerprinting and so on. Their applications in rice breeding programs are expected to revolutionize the way of variety development.
