A system and method for processing, i.e., sampling and tracking, plant material requires the ability to identify each plant in a plurality of plants. Initially, samples are taken from selected plants and are collected in respective storage locations in a magazine. During sampling, the identity of the plant source for each plant sample is stored. Further, the identity of each storage location receiving a plant sample is stored. Subsequently, the samples are transferred from the storage locations and are placed in respective wells of a receiving member for further downstream processing. Again, the identity of each well receiving a plant sample is stored. As a result, a plant sample in a well can be traced back to its plant source.
