Compared with other reduced-representation sequencing methods, library construction for genotyping-by-sequencing (GBS) is simpler and less expensive. However, elimination of size-selection steps results in libraries of more variable fragment size than with other reduced-representation methods, affecting several aspects of the data. To test the effect of restriction enzyme choice on library quality, the authors made GBS libraries with PstI (6-cutter), PstI/TaqI (4-cutter), or ApeKI (4.5-cutter) from the same set of DNAs from a cassava biparental population.
