The evaluation and identification of germplasm resources is an indispensable step in the breeding processes and have important roles in the selection and improvement of new varieties. This research intended to characterize coconut germplasm to determine the quantitative, qualitative, and morphological traits of the stem, leaf, and inflorescence and the fruit characteristics. Sixteen morphological and qualitative traits of 17 coconut (Cocos nucifera L.) germplasm resources from Hainan, China, were investigated to determine the characteristics and advantages of multiple germplasm lines to create the foundation for the cultivation and breeding of coconuts. The results of the correlation analysis, principal component analysis (PCA), and cluster analysis indicate a correlation between coconut germplasm factors and their contribution to coconut traits. The results revealed that stem girth at 0.2 m was the most obvious trait, along with the fruit flavor, edible rate, fat content, hole spacing, single fruit weight, and number of female flowers, which reflect most of the information regarding coconut traits and contribute to its value. The PCA and cluster analysis indicated that two high-yield and superior-quality sweet water dwarf coconut germplasms, named ‘15-19’ and ‘15-17’, were suitable for cultivation and production in Hainan, China. The results of this study act a far-reaching influence on the collection and utilization of coconut resources and have an impact on the development and progress of the coconut industry in China.

Cocos Nucifera L

Telah menjadi ingatan kolektif masyarakat Minahasa bahwa tanaman kelapa (Cocos nucifera L.) merupakan komoditas strategis yang memiliki peran sosial, budaya, dan ekonomi. Dalam konteks ini, pengolahan kelapa menjadikan kopra merupakan produk penting dalam meningkatkan kesejahteraan petani dan pembangunan di daerah Minahasa. Setelah Indonesia merdeka, terjadi perebutan monopoli tata niaga kopra baik melalui Pemerintah Pusat (Jakarta), Pemerintah Daerah (Minahasa), maupun militer (Teritorium VII Wirabuana). Hal ini menyebabkan tata niaga kopra semakin tidak terkendali. Ekspor kopra yang diharapkan dapat memberikan kontribusi ekonomi berubah menjadi masalah politik setelah munculnya peristiwa Permesta. Mengacu pada masalah tersebut, artikel ini bertujuan mendeskripsikan kondisi historis tata niaga kopra di Minahasa tahun 1946-1958. Secara metodologis, artikel ini merupakan studi yang bertumpu pada penelitian pustaka dan arsip. Akhirnya artikel ini menghasilkan kesimpulan bahwa kebijakan Pemerintah Pusat dalam mengatur tata niaga kopra menimbulkan kekecewaan dan diskriminasi bagi masyarakat Minahasa. Timbulnya kekecewaan masyarakat Minahasa menyebabkan tata niaga kopra sebagai kekuatan ekonomi berubah menjadi gerakan politik anti Pemerintah Pusat.   It has become a collective memory of the Minahasa community that coconut plants (Cocos nucifera L.) are strategic commodities that have a social, cultural, and economic role in their lives. In this context, coconut processing makes copra an important product in improving the welfare of farmers and regional development. After Indonesian independence, the copra trading system being monopolized by Copra Foundation, which controlled by central government (Jakarta), local government (Minahasa), and military (Teritorium VII Wirabuana. This causes the copra trade system to become increasingly out of control and dissatisfaction of the Minahasa community. Copra as an economic power turns into an anti-Central Government political movement. There was a takeover of a number of CopraFoundation assets in Manado, and established the Minahasa Coconut Foundation. Then came the demands of regional autonomy by forming the Province of North Sulawesi. The Port of Bitung as an in-out gateway for goods, was only used for barter trade and smuggling of copra abroad, especially Singapore which involved a number of Minahasa civilian officials and military officers. Copra exports are expected to contribute economically has turned into a political problem.

Bugel coastline areas have the potential for horticulture commodities development. This study's objectives were mapping protected Bugel coastline areas, land evaluation, and yield response of chili in an agroforestry system with coconut trees on Bugel coastline areas. The research was conducted during April-July, 2015, in Bugel coastline areas, Panjatan District, Kulonprogo Regency, Special Province of Yogyakarta. The first stage was the literature study and field mapping by BING satellite imagery. The second method was an actual and potential land evaluation using the FAO version, Sys criteria, and Sys limitation. The third method was using a randomized complete block design (RCBD) with three blocks as replications. The results showed that a local protected coastline area allowed for the agriculture and forestry crops is >200 meters from the furthest tide point. The actual and potential land evaluation in all agroforestry phases were not suitable and marginally suitable. The initial phase showed the highest fresh fruit weight by 100.30 grams/plant, compared with the intermediate and advanced phases by 88.13 grams/plant 71.54 grams/plant.

and is a cross-pollinator, so information about the genetic relationship between the accessions in germplasm collections is very important for selecting the prospective parent in crossbreeding. This research aims to determine the phylogenetic relationship of 24 Saccharum complex accessions and to verify the grouping of accessions using 37 morphological and three microsatellite molecular markers. Interpretation of morphological and molecular data was obtained from the analysis using the NTYSYpc-2.02i program. The results show that within the 24 accessions analyzed using morphological markers, some accessions did not cluster as the classification at the conservation time. This difference is due to the morphological markers, descriptions of characters that do not appear are considered as the same variables though in different morphological characters, so this increases the value of genetic similarity among accessions analyzed. In contrast, the grouping of molecular markers shows that each accession was grouped according to the classification at the conservation time. These accessions had a low genetic similarity of 0.20 with a broad genetic distance of 0.80. This broad genetic distance indicates that the twenty-four accessions have a distant genetic relationship with one another, so that the genetic diversity of these accessions is relatively high. The high genetic diversity in germplasm collections improves its potential as a crossing parent to obtain a high heterosis effect.
