Abstrak. Peningkatan hasil tanaman padi Sigupai/Yinzhan dapat dilakukan dengan menciptakan lingkungan tumbuh yang optimal, serta kebutuhan air yang cukup untuk perkembangan tanaman. Penelitian ini bertujuan untuk mengetahui karakter agronomi dan produktivitas pada padi BC4F2 hasil persilangan antara varietas Sigupai dan Yinzhan serta melihat peluang tanaman yang prosfektif untuk dilanjutkan. Penelitian ini dilaksanakan di Kebun Percobaan dan Laboratorium Pemuliaan Tanaman Jurusan Agroteknologi Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh. Pelaksanaan penelitian dimulai dari bulan Maret hingga bulan Juli 2023. Penelitian ini menggunakan Rancangan Acak Kelompok pola non faktorial dengan 3 ulangan, faktor yang diteliti yaitu galur/varietas padi hasil persilangan Sigupai/Yizhan (P) yang terdiri dari 7 taraf, yaitu : P1 : T5.3.12.1.3.12; P2 : T5.3.12.1.5.2; P3 : T9.1.7.6.9.12; P4 : T9.6.1.6.12.1; P5 : T9.8.8.3.5.9; P6 : T29.2.11.10.7.2; dan P7 : T29.8.5.2.12.12. Pengaruh perlakuan galur padi hasil persilangan Sigupai/Yinzhan berpengaruh sangat nyata terhadap tinggi tanaman padi pada umur 3, 4, 5, 6, 7, 8 MST dan saat panen, serta jumlah anakan 4, 5, 6, 7, dan 8 MST. Berpengaruh nyata terhadap berat 1000 biji, dan berpengaruh tidak nyata terhadap jumlah anakan 3 MST dan saat panen, panjang malai, umur berbunga, umur panen, berat gabah berisi per rumpun, dan estimasi hasil per hektar.

Abstract. Increasing the yield of Sigupai/Yinzhan rice plants can be done by creating an optimal growing environment, as well as sufficient water requirements for plant development. This study aims to determine the agronomic characteristics and productivity of BC4F2 rice as a result of crosses between Sigupai and Yinzhan varieties and to see opportunities for prospective plants to be continued. This research was conducted at the Experimental Garden and Plant Breeding Laboratory, Department of Agrotechnology, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh. The research was conducted from March to July 2023. This study used a non-factorial randomized block design with 3 replications. The factor studied was the rice line/variety resulting from the Sigupai/Yizhan (P) cross, which consisted of 7 levels, namely: P1 : T5.3.12.1.3.12; P2 : T5 .3.12.1.5.2; P3 : T9.1.7.6.9.12; P4 : T9.6.1.6.12.1; P5 : T9.8.8.3.5.9; P6 : T29.2.11.10.7.2; and P7 : T29.8.5.2.12.12. The effect of the treatment of the rice lines resulting from the Sigupai/Yinzhan cross had a very significant effect on the height of the rice plants at the ages of 3, 4, 5, 6, 7, 8 WAP and at harvest, as well as the number of tillers 4, 5, 6, 7, and 8 WAP. Significant effect on the weight of 1000 seeds, and not significant effect on the number of tillers 3 WAP and harvest time, panicle length, flowering age, harvest age, weight of unfilled grain per clump, and estimated yield per hectare.
