We provide a simple natural duality for the varieties generated by thenegation- and implication- free reduct of a finite MV-chain. We study thesevarieties through the dual equivalence thus obtained. For example, we fullycharacterize their algebraically closed, existentially closed and injectivemembers. We also explore the relationship between this natural duality andPriestley duality in terms of distributive skeletons and Priestley powers.
