Nypa grows mainly on the river banks. A number of nypa germplasm accessions were collected from three locations, namely North Minahasa (Wori district), South Minahasa (Paslaten District), and Southeast Minahasa (Tumbak District). The study aimed to determine the morphological differences amongst the collected germplasms and their correlation using multivariate analysis. The research used RCBD with 3 replications using five individual plants. The results showed that characters that have a high correlation for fruit weight are the fruit polar circumference (0.97), the fruit equatorial circumference (0.98), and the rachis length (0.84). An increase in one unit of these characters will increase the fruit weight. The average linkage method and heatmap with a cut-off point of 0.38 divided the accessions into two groups; the first group were Tumbak 1, Tumbak 2, Tumbak 3, Tumbak 4, and Tumbak 5, and the second group were Wori 1, Wori 2, Wori 3 , Wori 4, Wori 5, Paslaten 1, Paslaten 2, Paslaten 3, Paslaten 4, and Paslaten 5. Clustergram heatmap showed three groups with a high average of fruit polar circumference and weight per fruit, namely Paslaten 1, Paslaten 3, and Paslaten 5. The multivariate analysis clusters the accessions into groups with similar morphology.
