Abstrak/Abstract Background and Objective: Strawberry (Fragaria spp.) is known for producing fruit with high economic value and significant nutritional content. Recently, the growing diversity of cultivated strawberries in Indonesia has made it chalenging to distinguish the original characteristics of early ancestors and identify superior traits. The DNA barcoding, mainly through the chloroplast gene rbcL, offers a precise and detailed method for this identification. This research aims to reconstruct a phylogenetic tree, analyze genetic variation and determine the haplotype distribution of six strawberry cultivars from Java, particularly Yogyakarta and Central Java, based on the rbcL gene. Materials and Methods: The rbcL gene was amplified using DNA amplification techniques with rbcL-F and rbcL-R primers. The resulting data were analyzed to construct a phylogenetic tree using ML via IQtree software and BI using MrBayes software. The alignment results were used to determine genetic distances and identify polymorphic sites. This study assessed intraspecific genetic variation by examining h, identifying polymorphic sites, generating a haplotype network using PopART v1.7 and conducting PCoA with GenAIEx 6.503. Results: The results showed that the rbcL gene was successfuly amplified with a length of 1,221 bp after alignment with the GenBank database. Phylogenetic analysis using ML revealed that the six cultivars formed a single clade with a bootstrap value of 97. BI similarly indicated the formation of one clade with a posterior probability value of 1. Haplotype analysis showed that the cultivars ‘Californica’, ‘Knia’, ‘Mencir’, ‘Moha’ and ‘Geolhyang’ belonged to the same haplotype group, while the ‘Bali×Jumbo’ cultivar was placed in a different group. Conclusion: Haplotype network analysis and PCoA further indicated that the genetic variation of Indonesian strawberries, as assessed through the rbcL gene, is similar to strawberries from the United States and China.
