Citrus has been identified as a viable candidate for downstream processing and commercialization, according to Alex Agiwa, program manager for seed and planting materials at the Fresh Produce Development Agency (FPDA). Agiwa noted the widespread presence of exotic citrus species across Papua New Guinea, stating, "Commercialisation and downstreaming of citrus is possible in Papua New Guinea."
FPDA has earmarked citrus as an impact project, supported by national government funding since 2024. Agiwa emphasized the necessity for further research and development to determine suitable citrus species for both domestic and international markets. "Our local people are growing citrus of diverse varieties, but it does not get into our formal markets or overseas. It boils down to research and development," he remarked.
Addressing issues with rootstocks and scions through research trials is critical. Agiwa explained, "Comparison between the imported rootstocks and scions against the local ones must be done. The results from this research trial will prove which rootstocks and citrus species are to be selected and used for downstreaming and commercialization."
FPDA has established five permanent citrus nurseries, anticipating the importation of suitable rootstocks and budwood, potentially from the U.S.. Nurseries are located in Kerowaghi, Kurumul, Anglimp, Hagen Central, Baiyer, and a bush material nursery in Mumeng. These facilities maintain the genetic material of local citrus germplasm for ongoing research and improvement.
Nursery owners and selected farmers have received training in selecting optimal budwood and budding techniques for commercial citrus seedling production. In Morobe, trained farmers received budded citrus seedlings for trials in their districts and villages.
