Abstract

Pummelo plants in Magetan Regency were found to spread over several villages and their accessions have their own morphological and chemical characteristics.  This study was aimed at assessing the distribution and the number of pummelo accessions in Magetan Regency.  The study was conducted in Magetan Regency East Java from May to July 2015.  Observation was conducted on distribution marking and accession characteristics by using a survey method.  Results showed that the accessions of pummelo plants grown by farmers in Tambak Mas Village were varied but they were not evenly distributed.  Meanwhile, pummelo plants grown by farmers in Dukuh Village had uniform accessions with uneven distribution.  Results of  field observation obtained 13 pummelo accesions, namely Adas Duku, Adas Nambangan, Bali Putih, Bali Merah 1, Bali Merah 2, Gulung 1, Gulung 2, Gulung 3, Magetan, Jawa 1, Jawa 2, Jawa 3, dan Sri Nyonya.  The most commonly pummelo accessions found in Tambak Mas Village were Adas Nambangan and Adas Duku.  Meanwhile the most accessions planted in Bendo Village were Adas Duku and Sri Nyonya. Key words: pummelo, Adas Nambangan, Tambak Mas, Dukuh, survey method

Abstract

Magetan Regency was the production centre of pummelo that have many accessions  with various morphological and chemical characteristics, but only a few of them were identificated. This study was aimed at identifying morphological and chemical characteristics of pummelo fruits in Magetan Regency.  The study was conducted in the Biology Laboratory of Djuanda University, Bogor from May to July 2015.  Results showed with regard to their morphological characteristic, pomelo plants in this region were found to have spheroid and spheroid-pyriform fruits and the weight of their fruit parts, fruit core width, mesocarp thickness, fruit circle before peeling, fruit circle after peeling, number of fruit segments, number of developed seeds, and edible parts of the fruit were varied.  Chemical characteristics were also found to be varied with vitamin C content of 29.80−44.66 mg/100g, total soluble solids (TSS) content of 8.10−9.72°Brix, total titratable acidity (TAA) of 0.31−0.53 g/100 ml, and TSS/ TAA ratio of 17.69−28.58. Key words: production centre of pummelo, spheroid, vitamin C, TSS
