Okay since there are so many out there and I am not an strain expert, I decided to pick up an old issue of Heads magazine from about 8 months back, it has some of the best known indoor and outdoor strains listed and rated. I will list the outdoor strains that are higher indica varieties for you.

Bubblegun- Serious Seeds
Yumboldt-Sagarmatha
Romulan-Federation Seeds (I think they are Next Generation Seeds now)
Big Bud-Sensi Seeds
Holland's Hope-Dutch Passion
Mikado-Federation Seeds
Mango-Dutch Passion
Reclining Buddha-Soma Seeds
Early Pearl-Sensi Seeds
Sweet Tooth#3-Spice of Life
Matanuska Tundra-Sagamartha

This is all they listed. I am positive that you can find a lot of information on these popular strains from most seed websites and you can also find many other strains. These are the best they listed which are mostly Indica.
