Rootstocks in mango are always seedlings whether they are of zygotic or nucellar origin.

Clonal nucellar seedlings rootstocks have many advantages over heterogenous monoembryonic seedling rootstocks.

Clonal rootstocks have been selected for specific soil types and stress tolerance and behavior of the scion cultivar on clonal rootstocks is highly predictable.

With the intensification of fruit production due to socio-economic considerations, the role of rootstocks in commercial fruit production has increased considerably in the recent past.

Although rootstocks have several applications such as improving fruit quality, imparting adaptability to climatic and edaphic conditions and inducing dwarfing, the priorities of rootstocks selection in the tropics and subtropics have been focused mainly on vigour management and securing regular high fruit yields.

Mango is an important fruit crop of the tropical and subtropical regions. The yield is less than 10 t/ha in most of the growing countries.

Low planting densities based on the expected eventual tree size, propagation on seedling rootstocks of unknown pedigree and irregular bearing habits are some of major reasons for low orchard efficiency of mangoes in India.

In India and Mexico, monoembryonic seedlings are generally used as rootstocks.

Polyembryonic ‘Turpentine’ seedlings are used as rootstocks in Florida.

Either polyembryonic ‘Saber’ or ‘13-1’ seedlings are used as rootstocks in Israel.

In Australia, ‘Kensington’ seedlings are used as rootstock.

Throughout South-East Asia polyembryonic seedlings are used for rootstocks.

Use of nondescript mango stones for multiplication of rootstocks has led to enormous variation in the performance of mango clones in the orchards.

Some attempts have been made to standardize the rootstocks for various scion cultivars including the use of polyembryonic cultivars for vigour management, salinity drought, stress tolerance, fruit yield and quality.

There are relative advantages of polyembryonic rootstocks in mango.

In many regions including India and Mexico scion cultivars are still being propagated on heterogenous monoembryonic seedling rootstocks despite the demonstrated advantages of clonal nucellar rootstocks.

The potential of clonally propagated monoembryonic rootstock has not been properly investigated.

Other Mangifera sp. also have interesting attributes and should be screened for graft compatibility with mango.

The species that could be tested as rootstock for mango might extend mango cultivation to areas where abiotic and biotic stresses currently limit production and could provide a better source for dwarfing rootstocks for high density orcharding.

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.

The Chaunsa has a Brix rating in the 22 degree level which is unheard of!
Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.
Perhaps it is time for a GLOBAL taste test ???

Alphonso (mango)
From Wikipedia, the free encyclopedia

Alphonso (हापुस Haapoos in Marathi, હાફુસ in Gujarati, ಆಪೂಸ್ Aapoos in Kannada) is a mango cultivar that is considered by many[who?] to be one of the best in terms of sweetness, richness and flavor. 

It has considerable shelf life of a week after it is ripe making it exportable. 

It is also one of the most expensive kinds of mango and is grown mainly in Kokan region of western India.

 It is in season April through May and the fruit wei…

GMO MANGOES : Philippines has been working on it since 2000 ...

The genetic engineering used in modifying mangoes is extremely similar to that of the papaya. 

This is because both mangoes and papayas posses the ACC (ACS2) gene. 

This gene is responsible for producing ethylene and the influence of ethylene on the fruit is that it controls the ripening and senescence after the fruit has been picked. 

The main purpose of this genetic modifying is to reduce the amount of ethylene produced and to lengthen the onset of this gas. 

Scientist extract this gene from ripe mango var 'Caraboa' and after they separate the gene it is then cloned and sequenced. They can then insert the isolated gene back in the genome and it will act as a disturbance to the enzyme calling for more ethylene to be produced. 

Alternately, an ACC deaminase gene is inserted and its function is to convert ACC into a different substance which results in less ethylene being produced. 

Since genetically modified mangoes are on the market, scientists are free to explore other more effic…
