Indonesia is rich with pummelo ( Citrus maxima (Burn.) Merr.) germplasm, but its development is still very limited. Pummelo development efforts are directed to the availability of superior cultivars. The objective of this research was to gain information the developmental and quality differences of fruit of three pummelo accessions. This research was conducted at Cikabayan Research Station, IPB from December 2015 to October 2016. The research used a randomized complete block design with single factor named accession (Accession 1, Accession 2 and Accession 3) consisting of five replication. The results showed that fruit growth of all accessions continued to increase in early development phase, but fruit grew slowly in the maturity period. Accession 1 showed a higher in fruit volume and weight than the other accessions. The content of fruit juice of accession 1 was significantly higher than the Accession 3 but having no difference with Accession 2. Among accessions did not s...
