The highest CBD varieties that I'm aware, that are commercially available, are Soma A+ (aka Rock Bud by Soma Seeds) and Pineapple Thai available by clones in CA. These have been tested for their THC:CBD content in labs. But these are NOT the high CBD varieties being discussed in the media. Those have a much higher CBD content.

I'm afraid it will be many years before the high CBD varieties offered in CA dispensaries will be available from seed. These genetics are extremely rare, in high demand due to their media attention and hoarded by those who have them.
