This experiment was conducted to study phenotype of F 1 koi that obtained from gynogenesis at the Laboratory of Fish Genetic and Breeding, Department of Aquaculture, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University (IPB). Females koi used for this experiment were kohaku (white-red), hi-utsuri (red-black), and shiro-bekko (white-black); whereas males used kohaku , hi-utsuri , and shiro-bekko . Analysis on body coloration of fish was carried out at three months old. Results showed that gynogenesis from kohaku produced three types of koi, those were white koi, red koi and kohaku , and hi-utsuri produced red koi, black koi and hi-utsuri. Meanwhile, shiro-bekko by gynogenetic technique produce seven types of koi; those were white, red, black, kohaku , shiro-bekko , hi-utsuri and sanke (white-red-black koi). Survival rate of gynogenetic koi was lower then normal might be due to inbreeding stress. Key words :  Gynogenesis, phenotype, koi fish ( Cyprinus carpio ). ABSTRAK Studi tentang fenotip keturunan pertama ikan koi hasil ginogenesis telah dilakukan di Laboratorium Pengembangbiakan dan Genetika Ikan, Jurusan Budidaya Perairan, Fakultas Perikanan dan Ilmu Kelautan IPB. Ikan koi betina yang dipakai adalah kohaku (putih-merah), hi-utsuri (merah-hitam) dan shiro-bekko (putih-hitam), sedangkan jantannya adalah kohaku , hi-utsuri , dan shiro-bekko . Analisis warna pada ikan dilakukan setelah ikan berumur tiga bulan. Hasil penelitian menunjukkan bahwa ginogenesis pada ikan kohaku menghasilkan tiga jenis ikan koi, yaitu koi putih, koi merah dan kohaku ; pada ikan hi-utsuri dihasilkan ikan koi merah, koi hitam dan hi-utsuri. Sementara itu, teknik ginogenesis untuk ikan koi putih-hitam dihasilkan tujuh macam jenis ikan koi, yaitu koi putih, koi merah, koi hitam, kohaku , hi-utsuri , siro-bekko dan sanke (putih-merah-hitam). Tingkat kelangsungan hidup ikan ginogenetik lebih rendah daripada kontrol normalnya. Kata kunci :  Ginogenesis, fenotip, ikan koi ( Cyprinus carpio )
