This RIRDC report presents the findings from the project Evaluating Diversity array technology for the NSW rice industry. The aim and objectives of the project included; Examining diversity array technology (DArT) to build an understanding of the technology. Contructing a DArT reference panel necessary for ongoing DArT analysis of varieties and breeding lines. Finally to assess the potential of the technology for intergration into NSW Rice breeding program.  The project was divided into three phases. There were three key out comes of the project which included; highlighting the capability of DArT to provide detailed genetic fingerprints of varieties, to distinguish closely related lines, and to establish relationships between lines providing useful information for choosing parental combinations for breeding. The project concluded that the future association studies relating agronomic and grain quality data will determine if DArT markers can replace existing molecular marker tests such as for fragrance. It is also concluded that DArT analysis will play an increasing role in the rice breeding program because the cost per marker is low, its highly automated system has high throughput capacity, and the data generated will have increasing value with continuing advances in bioinformatics.
