For mass I've seen northern light x critical and skunk x critical crosses yield crazy. Oilspill or romulan korean skunk crossed to critical would be promising, I've seen the powers of a good critical lol, but craziest yielding strain ive seen honestly was a weaker somewhat old-school Honduran or Moroccan strain that's still available, I'd have to double check the strain. sativas may take longer but the ones that really get big donkey dicks will double+ yields over something finishing 3-4 weeks sooner. My solid bet for consistent high yield would be a skunk cheese cross, especially with some critical in there. Moby dick and critical would be great, that Moby yields great. Hindu kush is another I should not forget.
In terms of squatter bushy plants with dense colas...royal kush 7, critical kush, and a gorilla glue pheno I once had did amazing. I've seen and heard great things about Godbud yields too, monster colas.
A recent heavy yielder I still need to post besides that romulan Korean skunk was briscos Ginger Grant. And a orange julius Hindu Kush pheno from a pool that came from a orange-berry pastry smelling Hindu Kush mother that yielded just as well. I do find some squatter plants in the more pure pool of Hindu kushes I have played with but they have yielded great too just needed support. Tuna kush, anyone with those is bound to get high yields.
My favorites I'd have to say for high yield without compromise on terpenes and how it feels to smoke, Hindu kush's and Moby Dick are nice safe bets. The best experience I had with a heavy yielder though was a critical mass northern light cross that smelled like silver haze. one of those distant memories... nothing like a fat jar of haze terps. I bet a critical mass super silver haze cross would bang!
Edit: Willie's ice cream punch chocolate diesel and stardawg romulan are also recent memories of great yielders. Briscos buttered bananas and also banana cough did very well filling my jars a few seasons back grown out into bushes after cropping. If rats hadn't foiled one of my grows, I could tell cinci's AiTR was headed for glory and would have thumped some big buds.
