Obviously Uganda is pretty much on the equator to intertropical zone, so should really be a sativa as most Indica strains don't grow to well or a sati and dominant strain.
You will need strains that have tropical characteristics and will easily adapt to these unique growing conditions. Or indeed consider trying auto as this would not need much work against yield and also opens the door to a lot more strains.
Here are some suggestions-
1 Acapulco Gold - pure sativa
2 Old timers haze - pure sativa
3 Chitrali - pure Sativa
4 Ciskei - pure sativa
5 Ethiopian - pure sativa
6 Neville's Haze - pure sativa
7 AMG - 80% sativa / 20% indica
8 Kerala - pure sativa
9 Waikiki queen - 70% sativa / 30% indica
10 Light of Jah - 70% sativa / 30% indica
Although, it maybe worth looking for local landrace strains that you breed with to create you own strain maybe...? Good luck buddy!
