      Abstract
      Wild cocoyam (Caladium bicolor(W.Aint)Vent) Blume) is one of the ornamental leaf plants. Conventionally,this plant reproduces vegetatively. So, the generation of new genotypes is rare. Effort to increase genetic variation of plant was conducted through somaclonal variation in in vitro culture. The research goal is to identify the phenotypic variation of wild cocoyam from tissue culture due to somaclonal variation. Young leaves were taken as the plant material. Murashige and Skoog (MS) medium added with BAP 10 mg/l and NAA 0,5 mg/l used as the basic medium. The research had three steps: initiation, multiplication and acclimatization which was done 2 times in time 2 month interval. Roots were more abundant than the average number of leaves and buds. While at the acclimatization step, morphological characters of leaves was observed at the age of 2 months after being acclimatized. The visual results of this research showed that regenerated plants have morphological characters that were different from it’s parent. The first subculture gained 5 plants while the second subculture gained 6 plants with phenotypic variation.
       
      Keladi merah (Caladium bicolor(W.Aint)Vent.) Blume) merupakan salah satu jenis tanaman hias daun. Secara konvensional, tanaman ini diperbanyak secara vegetatif sehingga pembentukan genotipe-genotipe baru tergolong sempit. Upaya peningkatan ragam genetik dilakukan dengan variasi somaklonal yaitu melalui organogenesis in vitro. Penelitian ini bertujuan untuk mengidentifikasi variasi fenotipik keladi merah hasil variasi somaklonal dari kultur jaringan. Bahan tanaman yang digunakan adalah daun muda tanaman keladi merah. Media dasar yang digunakan adalah Murashige and Skoog (MS) yang ditambahkan BAP 10 mg/l dan NAA 0,5 mg/l. Penelitian terdiri dari 3 tahap yaitu inisiasi, multiplikasi dan aklimatisasi. Pada tahap inisiasi eksplan membentuk tunas pada 8 MSK. Tahap multiplikasi dilakukan 2 kali dengan interval waktu 2 bulan; jumlah akar menunjukkan nilai yang tinggi dibandingkan rerata jumlah daun dan tunas. Pada tahap aklimatisasi parameter yang diamati adalah karakter morfologi dan warna daun pada umur dua bulan setelah diaklimatisasi. Hasil penelitian menunjukkan bahwa secara visual tanaman hasil multiplikasi memiliki karakter morfologi yang berbeda dengan tanaman induknya. Dari hasil subkultur ke-1 diperoleh 5 tanaman sedangkan subkultur ke-2 diperoleh 6 tanaman yang bervariasi
