Abstrak. Persilangan padi Sigupai dengan IRBB27 berguna untuk meningkatkan kualitas padi Aceh, maka
dihasilkan benih Inbrida F9 melalui seleksi agronomi dan molekuler. Penelitian ini bertujuan untuk mengetahui
pertumbuhan dan hasil beberapa genotipe padi Inbrida F9 pada lahan aerobik. Penelitian ini dilaksanakan di lahan
Aceh Rice Research Institute, Universitas Syiah Kuala, Darussalam, Banda Aceh. Faktor yang diteliti adalah
genotipe F9 hasil persilangan varietas Sigupai dengan IRBB27 terdapat 14 genotipe (UA 1, UA 2, UA 4, UA 5, UA
6, UA 7, UA 8, UA 9, UA 10, UA 11, UA 12, UA 14, UA 15, dan UA 17) dan 1 varietas padi Mustajab sebagai
pembanding. Penelitian ini menggunakan Rancangan Acak Kelompok pola non faktorial. Hasil penelitian pada
tinggi tanaman padi umur 2 dan 4 MST yang terbaik dijumpai pada genotipe UA 7, tinggi tanaman umur 6, 8
MST, Jumlah anakan maksimum, umur berbunga dan Jumlah malai per plot yang terbaik dijumpai pada UA 9,
tinggi tanaman saat panen yang terbaik dijumpai pada genotipe UA 1, UA 4, UA 7, UA 8, UA 9, UA 11, UA 14, dan
UA 17. Umur panen terbaik dijumpai pada genotipe UA 10. Jumlah malai per rumpun yang terbaik dijumpai pada
genotipe UA 3 dan UA 9. Panjang malai per rumpun yang cenderung lebih baik pada genotipe UA 1. Bobot malai
per rumpun, bobot gabah bernas per rumpun, indeks panen, dan potensi hasil ton ha-1
yang cenderung lebih tinggi
pada genotipe UA 11. Bobot gabah hampa per rumpun cenderung lebih sedikit pada genotipe UA 17 dan bobot
1.000 butir yang cenderung lebih banyak pada genotipe UA 17.

Abstract. Crossing Sigupai rice with IRBB27 is useful for improving the quality of Aceh rice, resulting in F9 inbred seeds through agronomic and molecular selection. This research aims to determine the growth and yield of several F9 Inbred rice genotypes on aerobic land. This research was carried out on the grounds of the Aceh Rice Research Institute, Syiah Kuala University, Darussalam, Banda Aceh. The factors studied were the F9 genotype resulting from crossing the Sigupai variety with IRBB27, there were 14 genotypes (UA 1, UA 2, UA 4, UA 5, UA 6, UA 7, UA 8, UA 9, UA 10, UA 11, UA 12, UA 14, UA 15, and UA 17) and 1 Mustajab rice variety as a comparison. This research used a non-factorial randomized block design. The results of research on the best height of rice plants aged 2 and 4 WAP were found in the UA 7 genotype, plant height aged 6, 8 WAP, maximum number of tillers, flowering age and the best number of panicles per plot were found in UA 9, plant height at harvest. The best were found in the genotypes UA 1, UA 4, UA 7, UA 8, UA 9, UA 11, UA 14, and UA 17. The best harvest age was found in the UA 10 genotype. The best number of panicles per clump was found in the UA 3 and UA 9 genotypes. The length of the panicles per clump tended to be better in the UA 1 genotype. The best number of panicles per clump was found in the UA 3 and UA 9 genotypes. The length of the panicles per clump tended to be better in the UA 1 genotype. Panicle weight per hill, weight of grainy grain per hill, harvest index, and potential yield of tonnes ha-1 tend to be higher in the UA 11 genotype. Empty grain weight per hill tends to be less in the UA 17 genotype and the weight of 1.000 grains tends to be higher. in the UA 17 genotype. Keywords: Cross, Productivity, Rice quality
