Kampar regency is one of center of pineapple farmings in Riau. Kampar pineapples are particularly known as sweet pineapples. The objective of this research was to analyze the genetic diversity of pineapple in Kampar Regency Riau Province based on morphological characteristics. Fifteen samples were taken using random purposive sampling technique which were then characterized morphologically according to the descriptors for pineapples. Result of the study showed that Manhattan genetic distanceamong 50 plants based on morphological traits was 0,247-0,878. All of individual plants were grouped at the dissimilarity level of 73%. These data indicated that Kampar pineapples could harbor a wide range of genetic variation which may need further confirmation especially by molecular assessment.
