Abstract
Identification and information on the genetic variability of sente plants need to be known as a basis for consideration in preparing strategies for conservation, breeding, and sustainable use of plant genetic resources and as a basis for future development of sente plants in the Pandeglang Regency. This research was conducted to determine the morphological characteristics and diversity of sente plant germplasm in Koroncong District, Pandeglang Regency. The research was conducted in several villages in the Koroncong sub-district, namely Paniis, Koroncong, and Gerendong villages from January to February 2023. This research used an exploratory survey method which consisted of collecting data from farmers and morphological characterization. The results of the analysis of diversity can be known using Minitab.20 software were displayed in the form of a dendrogram and PCA. The dendrogram is used to describe the level of diversity between sente plant species, while the PCA is used to determine the distinguishing characteristics of the plant. The results of this study indicate that in the Koroncong sub-district, 28 accessions of sente were found which had a wide variety of morphological characters with the discovery of 2 types of sente, namely green sente and black sente. The identifying characters obtained were the color of the upper leaf blade, the color of the upper, middle, and lower third of the petiole, the color of the edge of the leaf blade, the color of the lower leaf veins, the color of the lower petiole ring, the color of the leaf midrib, the length of the petiole, the range of the plant, the length of the leaf, the width of the leaf, and plant height. The results of the dendrogram show that the germplasm of the sente plant in Koroncong District is divided into 3 clusters which have an eucledian distance of 0.00-14.69. More than one eucledian distance indicates that the genotypic relationship was very wide.

| Additional Information: | Identifikasi dan informasi keragaman genetik tanaman sente perlu diketahui sebagai dasar pertimbangan dalam menyusun strategi konservasi, pemuliaan, dan pemanfaatan sumber daya genetik tanaman secara berkelanjutan. Penelitian ini dilakukan untuk mengetahui ciri morfologi dan keanekaragaman plasma nutfah tumbuhan sente di Kecamatan Koroncong Kabupaten Pandeglang. Penelitian dilakukan di beberapa desa di Kecamatan Koroncong yaitu Desa Paniis, Koroncong, dan Gerendong pada bulan Januari sampai Februari 2023. Penelitian ini menggunakan metode survei eksploratif yang terdiri dari pengumpulan data dari petani dan karakterisasi morfologi. Hasil penelitian ini menunjukkan bahwa di Kecamatan Koroncong ditemukan 28 aksesi sente yang memiliki keragaman karakter morfologi yang luas dengan ditemukannya 2 jenis sente yaitu sente hijau dan sente hitam. Karakter penciri yang diperoleh yaitu warna helaian daun bagian atas, warna sepertiga atas, tengah, dan bawah tangkai daun, warna tepi helaian daun, warna urat daun bagian bawah, warna lingkar tangkai daun bawah, warna pelepah daun, panjang tangkai daun, jarak tanam, panjang daun, lebar daun, dan tinggi tanaman yang dihasilkan dari Principal Component Analysis (PCA). Hasil dendrogram menunjukkan bahwa plasma nutfah tumbuhan sente di Kecamatan Koroncong terbagi menjadi 3 cluster yang memiliki jarak eucledian 0.00-14.69. Lebih dari satu jarak eucledian menunjukkan bahwa hubungan genotipik sangat luas. | ||||||||||||
