We study baryogenesis via leptogenesis in an extension of the Standard Modelby adding one right-handed neutrino and one triplet scalar. These heavyparticles contribute to the generation of tiny neutrino mass through seesawmechanism. The contribution of the heavy particles to the neutrino masses isinversely proportional to their corresponding masses. Considering leptogenesisis achieved by the decay of the right-handed neutrino, the new source of CPasymmetry comes solely from the decay of the right-handed neutrino withone-loop vertex diagram involving the triplet scalar. The predictiveness of themodel is enhanced by introducing Fritzsch-type textures for the neutrino massmatrix and charged lepton mass matrix. We execute the parameter space studyfollowing the latest neutrino oscillation data. We study baryogenesis vialeptogenesis in the two-flavoured regime, using the zero textures, and showthat there is an enhancement in baryon asymmetry as compared to the unflavouredregime. For two-flavour leptogenesis we consider the suitable temperatureregime $T\subset\left[10^{10},10^{11}\right]$ GeV. We also study the commoncorrelation of CP violation between low and high-energy regimes using thegeometrical description of CP violation in terms of unitarity triangle.
