Where to get high oleic sunflower or safflower seeds?

I'm interested in growing high oleic varieties of sunflower or safflower for an oil crop. Where would I obtain such seeds? Do they exist as heirloom varieties, or only as modern hybrids?

And further, how would I beed for this characteristic?

I think if you looked around a bit, there would be some seed exchanges that may have heirlooms, but you may have to just start out with a hybrid and re-select from that.  I'm not sure what the standard test is for the higher oleic content.....can't help you there.  Good luck!

I believe Black Oil Sunflower seeds contain high levels of oleic acids.
