Collector Notes

Better field observations, nursery descriptions, or primary breeding records can be added as they become available.
Mangopedia Personal Experience
A Nam Doc Mai #4 mango tasted by Mangopedia measured 20.0 Brix and came across as extremely sweet, rich, smooth, and essentially fiberless. Among mangoes, Nam Doc Mai types are one of Mangopedia’s strongest recommendations for anyone who wants a very sweet mango with a smooth eating texture.
The flavor has a clear Thai profile with floral notes and a honey-like sweetness. For someone who wants to understand the classic Thai mango flavor, Nam Doc Mai is one of the best mangoes to taste because many Thai varieties seem to carry some version of that Nam Doc Mai character.
The fruit is very smooth and juicy with little to no fiber. The sweetness is the main feature, and the floral Thai flavor is pleasant and distinctive. The downside is that the flavor can feel somewhat narrow after a while: it is so sweet and smooth that mango enthusiasts may eventually want a variety with more complexity, tartness, or a different flavor direction.
The Nam Doc Mai tree grown by Mangopedia is small and does not produce heavily so far, but when it starts growing it can put on growth quickly while still staying fairly compact. This may make it a good candidate for a small-yard mango tree if pruned yearly to maintain size, though heavy pruning could affect production and should be tested over time. Nam Doc Mai is also known for producing multiple blooms in a year, which may give growers chances for mango crops at different points in the season.
