We study the influence of host galaxy morphology on LC parameters of the JLA data.
- class="label">•
The α parameter decreases from elliptical/lenticular to late-type spiral galaxies.
- class="label">•
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.
- class="label">•
SNe Ia in late-type spiral galaxies are more homogeneous in comparison with others.
