- Monopoly: all the available coconut seednuts are officially sold by the national institution in charge; other seednuts exchanges are obviously occurring among farmers, but they are considered as part of the traditional and informal system without any link with R&D institutions. Such a situation existed, at least until recently, in Vanuatu and Côte d’Ivoire.
- Centralized design: such as done in Sri Lanka, an important part of the seednuts is collected from farmers, then certified by the national institution and released to other stakeholders.
- Mid-centralized design: seednuts are also produced and sold by farmers, but benefiting of the advices and of the certification of national institutions.
- Distributed design: seednuts are produced by private stakeholders without any link with national R&D institutions.
5) Plant again Red Dwarfs and/or selected Green Talls on the available space.
This design was presented by using as parent the Malayan Red Dwarf which is a strongly autogamous variety. For producing hybrids seednuts, this dwarf variety needs to be emasculated. Other Red Dwarf varieties could also be used instead of the Malayan. Some varieties especially interesting are the Allogamous Compact Red Dwarf recently discovered in French Polynesia and Fiji. By using such allogamous Dwarf, it could be expected to produce up to 50% hybrid seednuts without making any emasculation; such an economy of labour and manpower could allow to strongly reduce the cost of hybrid coconut seednuts.
