Popis:	We used the ugr magnitudes of 1,437,467 F-G type main-sequence stars with metal abundance -250) of the Milky Way Galaxy. The radial metallicity gradient d[Fe/H]/dR=-0.042(0.011) dex/kpc estimated for the stars with 1.315 kpc) in three R distance intervals, 6 Comment: 30 pages, 9 figures and 4 tables, accepted for publication in Advances in Space Research
