    Abstract Yield Trial of Upland Rice Promising Lines. During the year of 2009, advance yield trials involving a total of 17 selected promising lines developed by the Indonesian Center for Rice Research, have been conducted in eight locations. These eight experimental locations were Tamanbogo and Pekalongan (East Lampung), Sukabumi and Indramayu (West Java), Banjarnegara (Central Java), Blora and Pacitan (East Java), and Sitiung (West Sumatra). In each location, the trial was arranged in a Randomized Block Design with four replications. Three varieties, Limboto, Batutegi, and Situ Patenggang, were planted as the check plants. The objectives of these experiments were to identify upland rice promising lines adaptive to environmental stress, bear high yielding character, and possess good grain quality. Results of these experiments indicated that the promising line of TB490B-TB-14-3 yielded higher than the three check rice varieties in five locations, Blora, Indramayu, Pacitan, Pekalongan, and Sukabumi. The promising lines of B11338F-TB-26 yielded higher than the check rice plants in three locations, Banjarnegara, Pacitan, and Sukabumi. While the promising line of IR30176-B-2-R-1 yielded higher than the check rice plants in two locations, Pacitan and Sitiung. Two promising lines, namely TB409C-TB-1-2-1 and TB490C-TB-1-21-MR-1-1 yielded higher than the check rice plants in two locations, Indramayu and Sitiung. There evaluation also indicated that the average yield of nine promising lines were higher than that of the cultivars commonly grown in the areas. These nine lines were B11338F-TB-26, B11577E-MR-12-1-1, B11577E-MR-B-13-1-1-5-5, BP702C-Si-5-1-12, B11577E-MR-12-1, IR30176-B-2-R-1. TB490C-TB-14-3, TB490C-TB-1-2-1, and TB490C-TB-1-21-MR-1-1. The highest yield was demonstrated by B11338F-TB-26 and IR30176-B-2-R-1, in Banjarnegara and Sitiung, respectively. Eight promising lines performed good quality character. The promising line of B11338F TB-26 produced the highest milled head rice and posed soft texture, the B11580-MR-7-1-1 was aromatic, and BP19768-2-3-7-TB-1-1 performed the highest head rice with medium texture. Abstrak Pada tahun 2009 telah dilakukan uji daya hasil 17 galur harapan terpilih hasil penelitian Balai Besar Penelitian Tanaman Padi di 8 lokasi, Tamanbogo dan, Pekalongan (Lampung Timur), Sukabumi dan Indramayu (Jawa Barat), Banjarnegara (Jawa Tengah). Blora dan Pacitan (Jawa Timur), dan Sitiung (Sumatera Barat). Percobaan disusun dalam Rancangan Acak Kelompok lengkap dengan empat ulangan. Varietas-varietas Limboto, Batutegi, dan Situ Patenggang. ditanan sebagai pembanding. Tujuan penelitian ini adalah untuk mengidentifikasi galur harapan padi yang mampu beradaptasi baik di lahan kering, berdaya hasil tinggi, dan memiliki mutu beras yang baik. Hasil penelitian menunjukkan bahwa galur harapan TB490B-TB-14-3 memberikan hasil yang lebih tinggi dari semua varietas pembanding di 5 lingkungan, Blora, Indramayu, Pacitan, Pekalongan, dan Sukabumi, diikuti oleh galur B11338F-TB-26 di tiga lingkungan, Banjarnegara, Pacitan, dan Sukabumi: galur IR30176-B-2-R-1 di dua lingkungan Pacitan dan Sitiung, dan galur TB409C-TB-1-2-1 dan TB4960 TB-1-21-MR-1-1 di dua lingkungan, Indramayu dan Sitiung. Sembilan dari 17 galur harapan yang diuji menunjukkan hasil yang lebih tinggi dari hasil padi yang biasa ditanam di 8 lokasi tersebut di atas. Galur-galur tersebut adalah B11338F-TB-26, B11577E-MR-12-1-1B11577E-MR-B-13-1-1-5-5, BP702C-Si-5-1-12, B11577E-MR-12-1, IR30176-B-2-R-1, TB490C-TB-14-3, TB490C-TB-1-2-1, dan TB490C-TB-1-21-MR-1-1. Hasil tertinggi sebesar 6,18 t/ha dicapai olch galur B11338F-TB-26 di Banjarnegara, diikuti oleh galur IR30176-B-2-R-1 sebesar 6,15 t/ha di Sitiung. Pada pengujian ini terdapat 8 galur yang memiliki mutu beras baik. Galur B11338F-TB-26 memiliki rendemen beras kepala 84% dengan tekstur nasi yang pulen, galur B11580-MR-7-1-1 memiliki sifat beras yang aromatik, sedangkan galur BP19768-2-3-7-T8-1-1 memiliki rendemen beras kepala tertinggi (94%) dan memiliki rasa nasi sedang.
