Visayas State U develops dipstick kit to find real PH carabao mango seedlings
Researchers from the Visayas State University have developed a diagnostic kit to identify what scientists call ‘true-to-type’ carabao mangoes.
In a release, the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD) said the development of the tool addresses the problem of mislabelling of Philippine carabao mango seedlings in many nurseries in the country.
The Philippine carabao mango is the one that enjoys huge demand from export markets.
With the technology, farmers can determine if the planting materials sold to them by nurseries are the ‘true-to-type’ Philippine carabao mangoes.
The project that developed the technology, dubbed Genetic Markers and Immuno-based Identification of Philippine Carabao Mango, was done by VSU in collaboration with the University of Southern Mindanao and funded by the PCAARRD.
The dipstick kit is disposable and reacts when dipped into the mango leaf extract. A real Philippine carabao mango will show a dark purple line and other varieties will not provide the same reaction.
In 2011, the Philippines exported some 21,081 metric tons for fresh mango worth US$16 million to Hong Kong, Japan, South Korea, Singapore, and the USA.
