Bombay is sort of the prototypical example of what I call the Indian/West Indian flavor group of mangos. Lots of spice with a pronounced resin note. This is different from the Indian/Alphonso group which includes mangos like Carrie and Angie, and of course Alphonso and Kesar among others.
So varieties to consider in that Bombay group include:
Apricot
Emerald
Sunrise
Jakarta
Iman Passand/Alampur Baneshan
Buxton Spice
White Piri
ST Maui (debatable if it belongs in this classification)
Zill O-15
Panchadara Kalassa
Little Gem
Lady’s Choice
Zill 36-43
Fake/ USDA Taymour
Phoenix…..(depends on the day , sometimes it’s more classic subacid)
I think Sunrise is a GREAT recommendation with the caveat that it’s a pretty large tree.
Emerald is pretty good and a much less vigorous tree than Bombay, but a small fruit and tricky to harvest before it drops. You have to pay close attention as the fruit nears maturity.
Apricot is very promising and tastes almost identical to Bombay. Still evaluating it but it seems to Fruit a lot easier than Bombay.
White Piri, Iman Passand, ST Maui and Panchadara Kalassa are my favorite tasting Indian/West Indian types, but I like or love everything on that list.
