Abstract
AbstrakJawer kotok (Plectranthus scutellariodes (L) R.Br.) selain berfungsi sebagai tanaman obat, sering digunakan sebagai tanaman hias karena bentuk dan warna daunnya yang indah. Balai Penelitian Tanaman Rempah dan Obat (BALITTRO) memiliki lima aksesi Jawer kotok yang belum teridentifikasi keragaman genetiknya. Koleksi tersebut perlu dikarakterisasi untuk mendapatkan data morfologi tanaman yang dapat digunakan sebagai pembanding antartanaman secara cepat. Identifikasi keragaman genetik dapat menggunakan karakter morfologi ataupun marka molekuler seperti Random Amplified Polymorphic DNA (RAPD). Penelitian ini bertujuan menganalisis keragaman genetik lima aksesi Jawer kotok berdasarkan karakter morfologi dan marka RAPD. Bahan tanaman yang digunakan adalah lima aksesi Jawer kotok koleksi kebun percobaan Cimanggu BALITTRO, Bogor Jawa-Barat. Karakteristik morfologi yang diamati meliputi habitus, daun, batang, dan bunga. DNA diekstraksi dari daun segar dengan metode CTAB kemudian diamplifikasi menggunakan 20 primer RAPD. Analisa kekerabatan menggunakan metode Gower dan UPGMA dengan software PBSTAT. Hasil penelitian menunjukkan terdapat keragaman pada bentuk daun, bentuk ujung daun, warna daun, dan warna corak daun. Analisis molekuler menunjukkan primer OPK 20, OPB 8, OPD 11, dan OPB 13 merupakan primer dengan polimorfisme tertinggi. Kelima aksesi berdasarkan karakter morfologi dan RAPD memiliki hubungan kekerabatan antara 0,5–0,8. Hubungan kekerabatan terjauh adalah aksesi JK1dan JK5, sedangkan kekerabatan terdekat pada aksesi JK3 dan JK4. Karakter daun merupakan karakter dengan keragaman genetik yang tinggi, dan dapat dijadikan kriteria sebagai penciri utama.AbstractJawer kotok (Plectranthus scutellarioides (L) R.Br.) apart from functioning as a medicinal plant, is often used as an ornamental plant because of the beautiful shape and color of its leaves.
