ABSTRACT

In modern plant breeding, DNA marker analyses are of increasing importance and, as the methods become more widely adopted, the capacity for high-throughput analyses at low cost is crucial for its practical use. Automation of the analysis processes is a way to meet these requirements. In order to achieve this, while keeping adequate flexibility in the analysis processes, Svalöf Weibull AB (SW) has developed a fully automated polymerase chain reaction system. It has been evaluated on barley and canola lines and is capable of analysing up to 2200 samples per day at a cost of 0,24 € per analysis for marker-assisted selection and quality control of genetically modified organisms. A detailed description of this system is given, and improvements to the throughput and applications are discussed.
