If you imported the image or layer from a JPeG (.jpg)
file, it will not have an alpha property for that layer.

Use menu: Layer / Transparency / Add alpha channel

Delete will then (by default) make the deleted section
transparent.

When you save back to a JPeG, GIMP will paint the
background (of the saved image only) white.

Save into an XCF file to retain all of the layers,
transparency, etc.
