Most of the theories proposed to explain the origin of lenticular galaxies (S0) are based on the results of differents dynamics processes on normal spiral galaxies, such as the interaction with the intracluster medium, the ram-pressure stripping, the galacticharassment, etc. The presence of S0s in low density environments can hardly be justified only by these mechanisms. Due to close relationship between the galaxies and their associated globular cluster (GC) systems, the latter allow us to compare the predictions of different galaxy formation models with observational data. We present our first results of the photometric study of the GC systems associated to the lenticular galaxies NGC2549, NGC2612, NGC2880, NGC3414, NGC5838 and NGC6861. To do this, we used deep Gemini/GMOS images in the filters g', r' and i'.
