Postharvest physiological deterioration in cassava

Cassava roots can only be utilized quickly because the roots suffer physiological damage in only 1?3 days after harvest because of postharvest physiological deterioration (PPD). Once the cassava roots are physiologically damaged, they cannot either be consumed or marketed. Indonesia is the second-largest cassava producer in Southeast Asia that is most used for food and feeds. Unless there is a solution, the PPD problem may become the main obstacle in cassava production.Therefore, finding solutions to the PPD problem in cassava is necessary, may be approached either?by treatment to inhibit PPD occurrences, identification of tolerance accessions among cassava?germplasm, and development of PPD tolerance cassava through breeding programs. In our?research, the identification method was done by applying various staining methods to detect color?changes associated with PPD symptoms during the cassava storage period and then compared to?the conventional observation of PPD symptoms. Subsequently, the effective staining approaches?are used to evaluate various genotypes' responses in the cassava germplasm collections. Finally, the?breeding approaches to develop PPD tolerance cassava varieties are outlined. Hopefully, with these?research results, the solution for PPD problems associated with cassava production in Indonesia?will be available.
