Abstract
Anggrek Phalaenopsis memiliki nilai komersial yang tinggi, karena keindahannya dapat dinikmati sepanjang tahun. Hal tersebut berdampak pada kebutuhan benih tanaman yang semakin meningkat. Salah satu cara penyediaan benih secara massal adalah melalui perbanyakan klonal secara in vitro sehingga perlu dilakukan studi kualitas regeneran hasil perbanyakan klonal untuk menjamin ketersediaan benih dengan kualitas baik. Penelitian bertujuan menguji kualitas regeneran yang dihasilkan dari perbanyakan klonal secara in vitro beberapa varietas Phalaenopsis dengan menggunakan eksplan yang berbeda.
