Supernovae are explosion of stars which are triggered by either implosion of the core or thermonuclear runaway. Observationally, it is found that some of the Supernovae (SNe) termed as core-collapse SNe, are associated with Gamma-ray Bursts (GRBs). GRBs associated with CCSNe are threads linking nature’s two grandest explosions. In this project, I present an overview of observational properties of Supernovae associated with long duration Gamma-ray Bursts. I describe here properties of possible progenitor stars that could drive core-collapse among some of the massive stars producing long duration GRBs. Observed properties like kinetic energies and luminosities of SNe associated with GRBs appear to be greater than those measured in case of ordinary CCSNe. Most of SNe associated with GRBs are of broad-lined type Ic, but not such SNe of type Ic are associated with GRBs. Properties like, mass, metallicity and degree of differential rotation in the collapsing iron core of massive stars etc. could be potential driving reasons to produce GRBs.
