We study the influence of host galaxy morphology on LC parameters of the JLA data.
The α parameter decreases from elliptical/lenticular to late-type spiral galaxies.
In an old stellar population SNe Ia are fainter after stretch and colour corrections.
The host galaxy morphology affects the residual dispersion on the Hubble diagram.
SNe Ia in late-type spiral galaxies are more homogeneous in comparison with others.
