水稻SNP芯片 GeneChip® Rice 44K SNP Genotyping Array The GeneChip® Rice 44K SNP Genotyping Array

The GeneChip® Rice 44K SNP Genotyping Array is designed to detect common genetic variants within and between the major subpopulations of rice, including indica, aus, tropical japonica, temperate japonica, and group V aromatic. With the arrays high resolution and superior genomic coverage, researchers can now collaborate internationally to easily assay the natural variation of rice varieties worldwide to identify genes underlying important phenotypic traits (such as high-yielding varieties to increase rice production), understand genetic sources of variation and associated phenotypic changes, and differentiate varietals for fingerprinting and classification purposes. The GeneChip Rice 44K SNP Genotyping Array was developed in collaboration with Dr. Susan R. McCouch, a professor in the Department of Plant Breeding and Genetics at Cornell University, as well as a team of scientists from world-renowned rice research institutes and private sector partners. The Rice 44K Genotyping Array enables: Quick product identity confirmation Flexible and fast identification and classification of germplasm Identification of high-yield variants Genome-wide association mapping Tracking of disease genes Low-cost analysis — less than a penny per data point Fast turnaround from DNA to data Flexible sample input — send leaf tissue or extracted DNA Genetic variation analysis of any O. sativa strain Array specifications 44,100 SNPs ~1 SNP every 10 kb throughout the 12 chromosomes of rice 12 probes per SNP Median call rate of 95.9 percent for more than 400 diverse O. sativa (inbred) accessions Greater than 99 percent average pair-wise concordance of technical replicates Greater than 92 percent average call rate
