dc.descriptionPerakitan kultivar yang tahan terhadap penyakit busuk lunak yang disebabkan Erwinia carotovora dapat dilakukan dengan teknik induksi mutasi. Tujuan penelitian ialah mengetahui pengaruh mutagen etil metan sulfonat (EMS) terhadap perubahan genetik di antaranya kapasitas regenerasi tanaman anggrek Phalaenopsis pada kultur in vitro dan mengetahui lethal concentration (LC) mutagen EMS pada anggrek hibrida Phalaenopsis. Percobaan ditata dalam rancangan acak lengkap dengan sembilan perlakuan konsentrasi EMS dan diulang tiga kali. Mutagen kimia yang digunakan yaitu EMS dengan konsentrasi 0 ; 0,025 ; 0,050 ; 0,075 ; 0,1; 0,125 ; 0,15 ; 0,175;  dan 0,2%. Eksplan berupa meristem aksilar anggrek hibrida Phalaenopsis ditanam pada medium dasar MS+ 2 ml/l BA + 1 ml/l NAA dan diinkubasi pada ruang kultur. Hasil penelitian menunjukkan bahwa etil metan sulfonat memberi pengaruh pada pertumbuhan meristem hibrida Phalaenopsis dalam membentuk tunas. EMS dengan konsentrasi 0,025 dan 0,05% memberi pengaruh yang lebih baik terhadap jumlah tunas dan tinggi tunas. LC50 untuk karakter persentase pembentukan tunas ialah 0,112%. Terdapat dua konsentrasi EMS, yaitu 0,025 dan 0,05% yang memberi pengaruh terbaik pada pembentukan tunas hibrida Phalaenopsis. Diperoleh beberapa regeneran mutan potensial dari berbagai perlakukan < 0,15% EMS yang perlu diuji dengan isolat Erwinia carotovora. To improve cultivars resistance to soft rot disease caused by Erwinia carotovora can be done by using mutation induction. The research objective was to determine the effect of EMS mutagent Phalaenopsis hybrid to change the genetic i.e. capacity of plant regeneration in vitro culture and the lethal concentration (LC) of EMS mutagent in Phalaenopsis hybrid. The experiment was arranged in a completely randomized design with nine concentrations of EMS treatment and repeated three times. The mutagent of EMS concentrations used were 0, 0.025; 0.050; 0.075; 0.1; 0.125; 0.15; 0.175; and 0.2%. The meristem axilar as explant was be grown on basic medium MS suplemented with 2 ml/l BA + 1 ml/l NAA and incubated in culture room. The results showed that the influence on growth of EMS meristem Phalaenopsis hybrids. The EMS mutagent with concentration of 0.025 and 0.05% gave better effect to the high number of shoots and buds. LC50 of the percentage of bud formation character was 0.112%. Two EMS concentrations were 0.025 and 0.05% provided the best influence on the formation of shoot Phalaenopsis hybrid. There were many regenerants potential mutant from several EMS treatments < 0.15 % that should be  tested by isolate of E. carotovora.en-US
