We present CCD UBVIKC photometry in the regions of the open clusters (OCs) Berkeley 26, Czernik 27, Melotte 72, NGC 2479 and BH 37. We present possible solutions for the cluster fundamental parameters by match- ing theoretical isochrones to the cleaned color-magnitude diagrams. Based on the results obtained for the current cluster sample and using the recently updated version of the Dias et al.'s (2002) OC Catalogue, different relation- ships between the positions in the Galaxy of known OCs, their ages and their metallicities are reexamined.
