DArT markers: diversity analyses and mapping in Sorghum bicolor

DArT markers: diversity analyses and mapping in Sorghum bicolor. The sequential nature of gel-based marker systems entails low throughput and high costs per assay. Commonly used marker systems such as SSR and SNP are also dependent on sequence information. These limitations result in high cost per data point and significantly limit the capacity of breeding programs to obtain sufficient return on investment to justify the routine use of marker-assisted breeding for many traits and particularly quantitative traits.
