The framework of supersymmetric see-saw models are considered. The successful leptogenesis scenarios which are due to a decay of the right-handed neutrinos tends to require rather heavy right-handed neutrinos. On the other hand, a discrepancy of the anomalous magnetic moment of the muon reported between the experimental and theoretical results implies lighter supersymmetric particles. In the light of successful leptogenesis scenarios, this anomaly of the anomalous magnetic moment of the muon leads to sizable lepton-flavour violations. It is shown that for a hierarchical right-handed neutrino mass spectrum, {mu}{yields}e{gamma} is expected to be observed in near future experiments.
