If you are looking for an Orange flavor think most people would suggest Sub's Agent Orange, Here is his info I just copied and pasted from Subs strain guide
Agent Orange
Agent Orange is a very good producer with extremely resinous large dense buds. The smell is amazing with hints of Oranges, Lemons and the smell of a Whiskey Sour cocktail. The strain contains pigments that have the ability to turn maroon, purple with cool nights. The buzz is up and motivating and make smile. The strain is a very heavy producer yielding large flat topped colas and very dense heavy buds. It does very well outdoors reaching over 10 feet in northern California. Indoors it can be topped and produce full canopies and heavy colas.
1) Phenotypes- Two main variations one short and thick and one taller and more resinous.
2) Height- Very tall block head colas
3) Yield- Very Heavy but all in last weeks
4) Indoor/Outdoor
5) Best Way to Grow- Top and train into a bush.
6) Harvest Window-55-65 days
