The transition magnetic moments of Majorana neutrinos {mu}{sub {nu}{sub ij}} (ij=e{mu}, e{tau}, {mu}{tau}) are calculated in grand unified theory (GUT) constrained Minimal Supersymmetric Standard Model (MSSM) with explicit R-parity violation. It is assumed that neutrinos acquire masses via one-loop (quark-squark and lepton-slepton) radiative corrections. The mixing of squarks, sleptons, and quarks is considered explicitly. The connection between {mu}{sub {nu}{sub ij}} and the entries of neutrino mass matrix is studied. The current upper limits on {mu}{sub {nu}{sub ij}} are deduced from the elements of phenomenological neutrino mass matrix, which is reconstructed using the neutrino oscillation data and the lower bound on the neutrinoless double beta decay half-life. Further, the results for {mu}{sub {nu}{sub e}{sub {mu}}}, {mu}{sub {nu}{sub e}{sub {tau}}} and {mu}{sub {nu}{sub {mu}}{sub {tau}}} are presented for the cases of inverted and normal hierarchy of neutrino masses and different SUSY scenarios. The largest values are of the order of 10{sup -17} in units of Bohr magneton.
