    Abstract Agronomic Performances of Upland Rice Promising Lines in South Sumatra. The effort to provide food for the Indonesian would become more difficult in the future due primary to the high rate of population increase and the changes of productive agricultural land into non-agriculture function. There are a total of 385.407 ha dry land areas available in the Province of South Sumatra, which are potentially good to cultivate upland rice. Unfortunately, only a total of 52.679 ha (13.7%) were utilized, in which due to lack of knowledge of the farmers in utilizing the areas, hence the productivity was still low. Farmers do not know how to carry out the proper management of cropping rice in the upland ecosystem, while improved upland rice varieties were also still limited. A trial to evaluate two breeding lines of upland rice developed by the Indonesian Center for Rice Research was conducted in Sumbawa Village, Banyuasin III Sub-district, Banyuasin District, during the wet season of 2008/2009. The objective of the trial was to evaluate the adaptability and the yield potentials of these two breeding lines grown in the dry land of South Sumatra. These two breeding lines were planted in plot of 20 m² in size, arranged in a Randomized Block Design with three replications. Results of this evaluation indicated that the yields of SEB.8FA-67-5 and SEB.8FA-300-2 were 3.7 t and 4.3 V ha, respectively. Both rice breeding lines were medium and early maturing type of rice possessing attractive agronomic characters. Abstrak Perubahan fungsilahan irigasi produktif menjadi lahan non pertanian dan jumlah penduduk yang terus bertambah, menyebabkan upaya untuk menyediakan pangan bagi masyarakat Indonesia makin sulit. Untuk itu, perlu diusahakan alternatif lahan untuk menanam padi. Salah satu lahan yang belum dikelola secara intensif adalah lahan kering yang tersedia cukup luas di Indonesia. Di Provinsi Sumatera Selatan saja, lahan kering yang tersedia mencapai 385.407 ha sementara yang sudah dikelola baru mencapai 52.679 ha atau sekitar 13,7% dari luas lahan yang tersedia. Produksi yang diperoleh masih rendah, karena petani belum memahami teknik budidaya padi gogo yang baik serta varietas unggul padi gogo masih terbatas. Uji multilokasi galur harapan padi gogo telah dilaksanakan di Desa Sumbawa, Kecamatan Banyuasin III, Kabupaten Banyuasin pada MH 2008/2009. Tujuan kegiatan ini adalah untuk mempelajari adaptasi dan produktivitas galur harapan padi gogo di lahan kering dataran rendah Sumatera Selatan. Galur harapan padi gogo dari Balai Besar Penelitian Tanaman Padi, ditanam dalam petak dengan luas 20 m³ yang diatur dalam Rancangan Acak Kelompok dengan 3 ulangan. Hasil pengujian menunjukkan bahwa dua galur harapan padi gogo SEB.8FA-67-5 dan SEB.8FA-300-2 mampu menghasilkan berturut-turut 3,7 t dan 4,3 t/ha. Umur kedua galur harapan padi gogo ini sedang sampai genjah dengan penampilan agronomis yang menarik.
