Abundances of phosphorus (P) in 45 main sequence F-G type stars (including the Sun by using reflected light from the minor planet Vesta) in the metallicity range [Fe/H] from -0.4 to +0.3 have been determined. The effective temperatures of target stars range from 5500 to 6600 K. Two lines of P I at 9750.75 Å and at 9796.83 Å (multiplet No. 2) are analysed by using a profile fitting method. Significant star-to-star scatters up to 0.4 dex have been found at all metallicities. We find three stars (HD 9826, HD 20010, and HD 82328) in which values of [P/Fe] are lower than -0.20, showing that P is deficient with respect to Fe in these stars. Such objects have never been reported in the past and may have an impact on the theoretical studies of origin and evolution of P. The sample contains 18 stars with confirmed planets (not including the Sun) and no significant difference in abundance of P has been found between stars with planets and those with no confirmed planet.
