Molecular identity of native coconut (Cocos nucifera L.) germplasm from South Kalimantan, Indonesia

Abstract

Coconut (Cocos nucifera L.) is an agricultural commodity that is very prospective to be developed in Indonesia and other tropical countries, but its development is constrained by various factors. This study aimed to determine the genetic identity, as well as diversity and relationships of native coconut germplasm from South Kalimantan, Indonesia, using a cpDNA (matK) marker. The results show that this germplasm has a low-level genetic diversity, π% = 0.0258. However, the phylogenetic analysis revealed that native coconut germplasms from this region have separated into different clades, two for Maximum Likelihood and three for Neighbor-Joining, where Genjah Kuning 3 has closely related to an outgroup. Thus, this information is important as a fundamental reference in developing new high-yielding coconut in the future

Agro-industrial development and valorization of coconut fruit waste In Indonesia: A review

“…Based on its color form, this dwarf variety germplasm can be divided into three sub-varieties, namely dwarf green, dwarf red, and dwarf yellow. Furthermore, red dwarf can be divided into two different phenotype, namely Malay and Cameroon [6]. 20% of Indonesian coconut germplasm has been collected, mostly from wet climate dry lands [14].…”

“…Plants can flower at 1.5 years of age and initially harvest for three years. Fruit production per stem can reach 80-120 fruits per tree per year [6].…”

“…Indonesia's coconut exports until the quarter of 2020 were recorded at 988.3 thousand tons or USD 519.2 million. While the number of exports of Indonesian coconut derivative products is still relatively low, in 2019 it reached USD 2.17 billion, consisting of processed coconut meat of IDR 663.8 million tons, coconut shells of IDR 209.6 million, coconut water of IDR 35.3 million, and coconut fiber of USD 12.6 million [6].…”
