             We present CCD UBVIKC photometry in the regions of theopen clusters (OCs) Berkeley 26, Czernik 27, Melotte 72, NGC 2479 andBH 37. We present possible solutions for the cluster fundamental param-eters by matching theoretical isochrones to the cleaned color-magnitudediagrams. Based on the results obtained for the current cluster sampleand using the recently updated version of the Dias et al.’s (2002) OCCatalogue, different relationships between the positions in the Galaxy ofknown OCs, their ages and their metallicities are reexamined.
