The present invention is related to a cutting system. It is further related to a system for obtaining a sample of plant material and method. Such a system can for instance be used for DNA analysis as part of a plant breeding program. According to the invention, the cutting system comprises a cutting device having a hollow cutting element having a cutting edge facing a leaf of a plant to be sampled, a drive unit for rotating said cutting element about a longitudinal axis of said cutting element to cut through the leaf, and a gas flow direction unit for applying a suction force through the hollow cutting element. The cutting system further comprises a control unit for controlling the drive unit and the gas flow direction unit. According to the invention, the hollow cutting element is elongated and the control unit is configured to control the gas flow direction unit and the drive unit such that said suction force is applied during said cutting through the leaf, and preferably at least prior to said cutting through the leaf.
