marker assignment codes
The table below shows the "single letter marker type designator codes" used in the CropStore Nomenclature Conventions and elsewhere. The two main examples of their use in CropStore are for the "marker_assay_name" and "mapping_locus" the later being described in Choi et. al. 2007 TAG.
The main source of these codes is: De Vicente et. al. (2004) IPGRI report, Descriptors for genetic markers technologies
