Mango is commonly propagated on variable seedling rootstocks of unknown
parentage, which may be responsible for clonal differences in the performance
of mango varieties.
No attempt has yet been made to standardize rootstocks in mango.
Successful clonal multiplication is a pre-requisite to any programme.
Air-layering of mango has not been used for propagation of clonal
rootstocks due to various limitations.
The modified method of stool-layering is an easy technique for multiplying
selected rootstocks in mango vegetatively.
