    Abstract

    This research aims to study the diversity and relationship of soursop plants in Java based on morphological and biochemical characters. Sampling was carried out at the plant soursop germplasm in Java covering West Java (Bogor), Central Java (Karanganyar, Sukoharjo), Yogyakarta (Kulon Progo, Gunung Kidul) and East Java (Ngawi, Pacitan). Sampling was done by purposive random sampling of ten plants each location. Observation of morphological characters of the parts soursop plants specifically include age, habitus, stems, leaves, flowers, fruits and seeds. Observations of the biochemical characters include reducing sugar content, moisture content, pH and the levels of vitamin C in the fruit soursop plants. To find soursop plants diversity, morphological and biochemical characters data were analyzed descriptively to determine the phylogenetic relationship while soursop plants data obtained then converted into binary data, calculated similarity index and genetic distance analysis (genetic distance) using the Group Average Clustering which integrated in program Numerical Taxonomy and Multivariate Analysis (NTSYS) version 2.10. Results showed that there are many diversity of morphological characters in Java includes stems, leaves, flowers, fruits and seeds as well as biochemical characters which include reducing sugar, water content, pH and levels of vitamin C. Based on morphological and biochemical characters, the nearest relationship soursop plants in Java are Sukoharjo and Bogor population with similarity coefficient 66.7%, while the most distant relationship are between Sukoharjo and Gunung Kidul population with similarity coefficient of 49.1%. Keywords: diversity, Annona muricata L., morphology, biochemical, Java Penelitian ini bertujuan untuk mempelajari keragaman tanaman sirsak di Jawa berdasarkan karakter morfologi dan biokimiawi serta mempelajari hubungan kekerabatan tanaman sirsak di Jawa berdasarkan karakter morfologi dan biokimiawi. Pengambilan sampel tanaman sirsak dilakukan pada plasma nutfah tanaman sirsak di Jawa yang meliputi Jawa Barat (Bogor), Jawa Tengah (Sukoharjo, Karanganyar), Jawa Timur (Ngawi, Pacitan) dan Yogyakarta (Kulonprogo, Gnung Kidul). Pengambilan sampel dilakukan secara purposive random sampling sebanyak 10 tanaman pada tiap lokasi. Pengamatan karakter morfologi dilakukan terhadap bagian-bagian tanaman sirsak secara spesifik meliputi umur tanaman, habitus, batang, daun, bunga, buah dan biji. Untuk pengamatan karakter biokimiawi dilakukan dengan menganalisis kandungan gula reduksi, kadar air, pH dan kadar vitamin C dalam buah tanaman sirsak. Untuk mengetahui keragaman tanaman sirsak, data karakter morfologi dan biokimiawi dianalisis secara deskriptif sedangkan untuk mengetahui hubungan kekerabatan tanaman sirsak data yang diperoleh kemudian dikonversikan menjadi data biner, dihitung indeks similaritasnya dan dilakukan analisis jarak genetik (genetic distance) dengan menggunakan metode Group Average Clustering yang terintegrasi dalam program Numerical Taxonomy and Multivariate Analysis (NTSYS) versi 2.10. Hasil penelitian menunjukkan adanya keragaman karakter morfologi tanaman sirsak di Jawa yang meliputi batang, daun, bunga, buah dan biji serta karakter biokimiawi yang meliputi gula reduksi, kadar air, pH dan kadar vitamin C. Berdasarkan karakter morfologi dan biokimiawi, hubungan kekerabatan tanaman sirsak di Jawa yang terdekat yaitu pada populasi Sukoharjo dan Bogor dengan koefisien kemiripan sebesar 66,7%, sedangkan hubungan kekerabatan yang paling jauh yaitu antara populasi Sukoharjo dan Gunung Kidul dengan koefisien kemiripan sebesar 49,1%.
