Controlled Pollination and Reproductive Strategies in Coconut: A Framework for Farmer‑Led Breeding, Seednut Production, and In Situ Conservation

This narrative review recommends an innovative, farmer-friendly controlled-pollinationapproach for smallholder farmers to produce their own coconut (Cocos nucifera) seednuts on farm.Over millennia, these smallholder farmers have created a wide range of coconut diversity andassociated traditional knowledge. However, for seednuts produced under natural, open pollination,the male parent identity is not known. Often, less than 10% of the offspring reproduce the desiredparental type and traits. This paper summarizes key aspects of coconut’s complex reproductivebiology in the context of its conservation and breeding. It outlines how small-scale farmers cancontribute to expanding and conserving in situ coconut genetic diversity. In some countries, thereare already profitable coconut seednut production companies. However, very few farmers currentlysell their seednuts, and these are only available in very limited quantities. Opportunities existfor smallholder farmers to start new profitable seednut businesses, especially in countries wherenational services release only a few coconut varieties, and where demand for coconut seednuts forreplanting is high. Measures are needed to establish farmer-produced quality seednut standards.Empowering smallholders to master pollination techniques could remove a longstanding barrier tococonut improvement. It also emphasizes a broader paradigm shift toward decentralized, farmerdrivenconservation and use systems.
