The lack of standard procedures in identifying mango varieties at the seedling stage is a major problem in the mango industry. Standardized procedures for identifying the variety of mango seedlings have been developed. The technology involves the physical examination of the young leaves or flushes where differences in color and direction of growth define a specific variety. This method focuses on the physical characteristics of mango seedlings and the chemical reactions of the mango leaf extract. This technique can also be applied in identifying mature mango trees. This method is being used by mango nursery owners and prospective mango growers.
