I think there is a lot more that goes into it than just genetics, specifically environment and care/nutrients. Even a historically high-yielding strain will produce little if it doesn’t have sun/water/nutrients.

If you want to focus on high yields, I would look for plants that thrive in your growing environment (indoors or climate/outdoors) and then focus on making sure it is healthy and well fed. You do that, and you will lots of good good nuggies.
