During the period of June 23-26, Ismail Maskromo – a PhD. (S3) graduate student associated with PMB Lab have gone to Jember, East Java to conduct Kopyor coconut survey in the region. The targets of his survey were to document existence of Kopyor coconut mutant at Jember areas, record existing Kopyor coconut provenances variation, and observe yield of Kopyor coconut fruits among those provenance evaluated.
Kopyor coconut exists in three regions around Jember, such as: (1) Desa Kesilir, Kecamatan Wuluhan (about 30 km from Jember), (2) Desa Pontang, Kecamatan Ambulu (about 10 km from Jember), and (3) Desa Mayangan, Kecamatan Gumuk Mas (about 50 km from Jember). Although two different Kopyor coconut (tall and Dwarf Kopyor coconuts) existed in those regions, Tall Kopyor coconut is more preferred to farmers than Dwarf one. The farmers prefer Tall Kopyor coconut since it has bigger fruit size that of Dwarf. Hence, the larger fruits is more presentable to the consumers than that of Dwarf one with relatively small fruit.
At the first site – Desa Kesilir, Kecamatan Wuluhan, Jember, most of the Kopyor coconut provenances are Tall Kopyor coconut type. Ismail was able to record 36 Tall Kopyor coconuts in this first site. He also took 10 samples of Kopyor coconut fruits and a representative of 10 leaf samples from different coconut provenances and a representative of stamens from one male parent for subsequent activities at IPB Bogor, and Pati, Central Java.
At the second site – Desa Pontang, Kecamatan Ambulu, Jember, most of the Kopyor coconut provenances are Dwarf Kopyor coconut type. At this site, however, it only exists two different color of the coconut fruits, such as: the Green (green dwarf Kopyor coconut) and yellow (yellow dwarf Kopyor coconut). Ismail was able to record 40 Dwarf Kopyor coconuts in this second site. He also took 2 samples of Kopyor coconut fruits and a representative of five leaf samples from Green Dwarf Kopyor coconut and five leaf samples from Yellow Dwarf one.
At the third site – Desa Mayangan, Kecamatan Gumuk Mas, Jember, most of the Kopyor coconut provenances are between 8-15 years age. The height of Kopyor coconut provenances ranged from 3-8 m. At this site, the number of existing Kopyor coconut provenances are 65 trees among a total of 147 trees surveyed.
The Kopyor coconut provenances in this site were grown using seedlings originated from Desa Kesilir, Kecamatan Wuluhan, Jember. Kopyor coconut trees at Desa Kesilir are planted in the fish pond border. From this site, Ismail obtained samples of Kopyor coconut fruits (12 nuts), leaf samples (obtained from 12 provenances), and a representative of stamens from two male parents for subsequent activities at IPB Bogor, and Pati, Central Java.
Results of the Kopyor coconut survey at Jember areas will be combined with those from other regions. Ismail will write the survey results as one chapter of his PhD dissertation. Part of his activities were supported by KKP3T Project on Kopyor coconut under Prof. Sudarsono coordination.
PMB Lab staffs and associated graduate students wish Ismail a success in following up the Kopyor coconut survey into publication. We hope that he will complete the publications as soon as possible.
