Yes, leucoplasts like other plastids have their own DNA. They have circular double-stranded DNA.

Does leucoplast have its own DNA?

Leucoplast is bound by two membranes,which lacks pigment but contain their own DNA and protein synthesizing machinery.

Do leucoplasts have DNA and ribosomes?

In addition, the leucoplast stroma is often less dense than chloroplasts stroma and contain several nucleoids with DNA fibrils. However, 70S ribosomes either scattered in the stroma or attached to the stroma reticulum or the envelope are not visible in ultrathin sections of leucoplasts stained with uranyl and lead.
