Abstrak. Padi Sigupai merupakan padi lokal dari Aceh bagian Barat. Sigupai memiliki banyak keunggulan yakni, aroma nasi yang harum pandan, rasa nasi yang pulen, serta lebih tahan kekeringan dan tahan terhadap hama dan penyakit tertentu. Penelitian ini bertujuan untuk mengetahui karakter agronomis, produktivitas serta menganalisis kualitas hasil galur hasil perbaikan padi Aceh Sigupai. Penelitian ini dilaksanakan di Kebun Percobaan Fakultas Pertanian 5°34'01.6LU-95°22'24.4BT ketinggian 7 mdpl, Laboratorium Genetika dan Pemuliaan Tanaman dan Laboratorium Ilmu dan Teknologi Benih, Departemen Agroteknologi Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh. Berlangsung dari bulan November 2023 sampai Mei 2024. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola non faktorial dengan 4 ulangan yang terdiri dari 7 genotipe yaitu: T5.3.12.1.3.12; T5.3.12.1.5.2; T9.1.7.6.9.12; T9.6.1.6.12.1; T9.8.8.3.5.9; T29.2.11.10.7.2; dan T29.8.5.2.12.12. Parameter yang diamati yaitu tinggi tanaman (cm), jumlah anakan (anakan), panjang malai (cm), umur berbunga (HSS), umur panen (HSS), bobot gabah berisi per rumpun (g), bobot 1000 biji (g), persentase gabah berisi (g), potensi hasil (ton ha-1), kadar amilosa, kadar amilopektin, kadar air, dan kadar beras berkapur. Hasil penelitian dari beberapa galur hasil perbaikan padi Aceh Sigupai berpengaruh sangat nyata terhadap tinggi tanaman umur 6, 8 MST dan pada saat panen, serta jumlah anakan
4, 6, 8 MST, dan pada saat panen, berat gabah berisi per rumpun, panjang malai, persentase gabah berisi, dan estimasi hasil per hektar. Berpengaruh tidak nyata terhadap tinggi tanaman padi 4 MST, umur berbunga, umur panen, dan berat 1000 biji. Potensi hasil berkisar antara 8,94-13,92 ton ha-1. kualitas kadar air dan beras berkapur galur hasil perbaikan padi Aceh Sigupai kadar air terendah terdapat pada galur T 29.2.11.10.7.2, sebesar 13,18 %, dan beras berkapur terendah terdapat pada galur T29.8.5.2.12 .12 yaitu sebesar 11%. Analisis kualitas hasil kadar amilosa dan amilopektin, amilosa berada pada kisaran 26,06- 28,58 % yang terendah pada galur T9.8.8.3.5.9 dengan kadar amilosa 26,06 %.

Abstract. Sigupai rice is a local rice from Western Aceh. Sigupai has many advantages, namely, the aroma of fragrant pandanus rice, the taste of fluffy rice, as well as more drought-resistant and resistant to certain pests and diseases. This study aims to determine the agronomic characters, productivity and analyze the yield quality of the improved strains of Aceh Sigupai rice. This research was conducted at the Experimental Garden of the Faculty of Agriculture 5°34'01.6LU-95°22'24.4BT, 7 meters above sea level, Laboratory of Genetics and Plant Breeding and Laboratory of Seed Science and Technology, Department of Agrotechnology, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh. It took place from November 2023 to May 2024. This study used a non-factorial pattern Randomized Group Design (RAK) with 4 replications consisting of 7 genotypes, namely: T5.3.12.1.3.12; T5.3.12.1.5.2; T9.1.7.6.9.12; T9.6.1.6.12.1; T9.8.8.3.5.9; T29.2.11.10.7.2; and T29.8.5.2.12.12. The parameters observed were plant height (cm), number of tillers (tillers), panicle length (cm), flowering age (HSS), harvesting age (HSS), weight of filled grain per clump (g), weight of 1000 seeds (g), percentage of filled grain (g), yield potential (tons ha-1), amylose content, amylopectin content, moisture content, and calcareous rice content. The results of the research of several strains of improved Aceh Sigupai rice have a very significant effect on plant height at 6, 8 weeks of planting and at harvest, as well as the number of tillers 4, 6, 8 weeks of planting, and at harvest, the weight of filled grain per clump, panicle length, percentage of filled grain, and estimated yield per hectare. It had no significant effect on rice plant height 4 weeks after planting, flowering age, harvesting age, and 1000 seeds weight. Potential yields ranged from 8.94-13.92 tons ha-1. quality of water content and calcareous rice strains of rice improvement results Aceh Sigupai lowest water content is in the strain T 29.2.11.10.7.2, at 13.18%, and the lowest calcareous rice is in the strain T29.8.5.2.12 .12 which is 11%. Analysis of the quality of the results of amylose and amylopectin levels, amylose is in the range of 26.06-28.58%, the lowest in strain T9.8.8.3.5.9 with amylose levels of 26.06%.
