[Principle of diversity arrays technology (DArT) and its applications in genetic research of plants].

Diversity arrays technology (DArT) is a microarray hybridization-based molecular marker technique, and a novel method to discover genetic polymorphic markers. DArT has recently been applied in genetic research of plants because of its characteristics of sequence-independent, high-throughput, fast, low-cost. We briefly introduce the principle, characteristics, protocol of DArT and its application in genetic research of plants.
