Varieties of mango

Yesterday I got a chance to visit an agricultural professor's house to pick up farm fresh, naturally grown ripe mangoes. The professor's mother asked me what varieties I would like. As textbook knowledge I know mango comes in different varieties. Practically, mango has been a synonym for 'banginapalli' variety. Admitted to her that I do not know of any varieties. She showed me 'mallika' 

, 'himasagar' and 'suvarnarekha' varieties along with regular banginapalli variety. Promptly chose a couple of mangoes a variety each to try. 

Tried the three varieties yesterday. Each is so different and distinct in taste and flavor. Overall, enjoyed the mango tasting exercise. Himasagar is the sweetest of them. Suvarnarekha is also sweet but has a distinct flavor and smell. Mallika not too sweet but thoroughly tasty.
