ABSTRACT

RAPD analysis was used to estimate relationships of four pineapple cultivars: 'Perola', 'Smooth Cayenne', 'Primavera', and 'Perolera'. Smooth Cayenne and Primavera were most closely related, followed by Perolera. Perola was more distant from the other three cultivars than they were from each other. These results confirmed genetic relationships derived by analyses of morphological and agronomic characters.

Keywords: genetic relationship; pineapple; Ananas comosus; polymorphic DNA.
