Let　U-q(osp(1　vertical　bar　2n))　be　the　quantized　enveloping　superalgebra　corresponding　to　the　Lie　superalgebra　osp(1　vertical　bar　2n).　In　terms　of　semistandard　Young　tableaux　satisfying　some　additional　conditions,　a　realization　of　crystal　graph　of　finite-dimensional　irreducible　modules　of　U-q(osp(1　vertical　bar　2n))　is　given.　Also,　the　generalized　Littlewood-Richardson　rule　for　tensor　product　of　crystal　graphs　is　established.
