Not completely landrace but Bodhi's DLA line are basically landrace kushes x with 88G13xHP to frost up the landrace genes.
Just chopped a DLA5, can't even begin to describe to smell, offensive to say the least.
I've had decent luck with older hard to pop seeds by soaking them in a mixture of 1/2 cup water & 1T hydrogen peroxide for 24 hours then into paper towels.
