| Abstrak/Abstract |
Pineapple (Ananas comosus (L.) Merr.) is one of the agricultural commodities in Indonesia that were widely cultivated with a variety of cultivars. Riau and Central Java Provinces are among the two largest pineapple-producing provinces in Indonesia. This study aimed to identify morphological variations and determine the phenetic relationship of pineapple cultivars in Central Java and Riau Provinces. A total of 27 pineapple accessions were evaluated using 44 morphological characteristics. The pineapple accessions in Central Java and Riau Provinces belonged to three cultivars, which were ‘Queen’, ‘Spanish’ and ‘Cayenne’. The highest variation in morphological characters was found in the leaves and fruit organs. Phenetic relationship produced two main clusters that separated ‘Queen’ and ‘Spanish’ from ‘Cayenne’. Based on PCA scatter biplot, this study found eight new characters that can be distinguish ‘Queen’, ‘Spanish’ and ‘Cayenne’. In 'Queen' and 'Spanish' clusters, the main contributing characters which were color of crown leaf spines, the spines on crown leaves, distribution of spines and sepal color. In the ‘Cayenne’ cluster from this study had four diagnostic characters, which were bracts color, leaf spine directions, fruit base leaf color and crown shape. This research will be encouraging several similar studies regarding pineapples both in Indonesia and in other largest pineapple-producing countries, such as Costa Rica, the Philippines and Brazil. © 2023 Friends Science Publishers
