Padi (Oryza sativa L.) merupakan salah satu tanaman pangan yang penting di Indonesia. Perakitan varietas baru melalui mutasi diperlukan untuk meningkatkan kualitas dan kuantitas hasil tanaman padi demi memenuhi kebutuhan pangan. Penelitian ini bertujuan untuk mengkarakterisasi arsitektur tanaman galur padi Super Mutant Aromatic Rice Technology hasil seleksi in vitro Sigupai Abdya. Penelitian dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Syiah Kuala, Darussalam, Banda Aceh, pada bulan Agustus sampai bulan Desember 2022. Rancangan percobaan yang digunakan adalah rancangan acak kelompok non faktorial dengan 14 taraf yaitu Sigupai Abdya sebagai tetua tanpa iradiasi sinar gamma, Mustajab, dan 12 galur mutan hasil seleksi in vitro generasi ke 2 (M2) serta menggunakan 3 ulangan. Hasil penelitian menunjukkan bahwa respon galur mutan padi berpengaruh sangat nyata terhadap parameter tinggi tanaman 30, 60, dan 90 HSPT, panjang daun, lebar daun, jumlah gabah per malai, bobot gabah berisi per rumpun, dan indeks panen, serta berpengaruh nyata terhadap jumlah anakan dan panjang malai, namun berpengaruh tidak nyata terhadap persentase gabah berisi per rumpun serta persentase gabah hampa per rumpun. Bentuk tanaman pada tetua Sigupai, pembanding dan 12 galur lainnya yaitu berbentuk tegak dengan sudut

Rice (Oryza sativa L.) is one of the important food crops in Indonesia. The assembly of new varieties through mutation is needed to improve the quality and quantity of rice crop yields to meet food needs. This study aims to characterize the plant architecture of the Super Mutant Aromatic Rice Technology rice line from in vitro selection of Sigupai Abdya. The study was conducted at the experimental garden of the Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh, from August to December 2022. The experimental design used was a non-factorial randomized block design with 14 levels, namely Sigupai Abdya as the parent without gamma ray irradiation, Mustajab, and 12 mutant lines from the 2nd generation in vitro selection (M2) and using 3 replications. The results showed that the response of the rice mutant lines had a very significant effect on the parameters of plant height at 30, 60, and 90 days after planting, leaf length, leaf width, number of grains per panicle, weight of filled grains per hill, and harvest index, and had a significant effect on the number of tillers and panicle length, but had no significant effect on the percentage of filled grains per hill and the percentage of empty grains per hill. The plant shape of the Sigupai parent, comparison and 12 other lines was upright with an angle of
