| Abstract: | The objectives of this research were to study the potential and yield stability of upland rice lines obtained from anther culture and their performance in the field. Ten upland rice doubled-haploid (DH) lines were tested for their potential yield in eight different locations (in Provinces of Lampung, West Java, Central Java, Yogyakarta, East Java - Indonesia) in the rainy season of 2010/2011 along with two check varieties (Way Rarem and Batutegi). In each location, the design was Randomized Complete Block Design with four replications. The results indicated that the line showing the most stable yield in different environment was I5-10-1-1 followed by WI-44, and IG-38. I5-10-1-1 produced 4.01 tons of dry grain per hectare. The line showing the highest yield was WI-44, and this line produced 4.72 tons of dry grain per hectare. Visualization with AMMI showed that IW-56 and IW-67 lines were specifically adapted in Purworejo, O18-b-1 was specifically adapted in Bogor, and IG-19 was specifically adapted in Malang. Upaya pengembangan teknologi yang ditempuh untuk meningkatkan produksi padi di lahan kering adalah melalui program pemuliaan tanaman. Perakitan varietas secara konvensional memerlukan waktu yang panjang (lebih dari 5 tahun), apabila menggabungkan sifat yang diinginkan dari berbagai varietas atau tetua. Kultur antera dilaporkan dapat menghasilkan tanaman dihaploid atau galur murni dalam waktu singkat. Stabilitas adalah kemampuan tanaman untuk mempertahankan daya hasil terhadap perubahan kondisi lingkungan. Pengujian stabilitas hasil melalui serangkaian uji multilokasi merupakan suatu tahapan penting sebelum varietas dilepas. Dari hasil uji multilokasi diharapkan dapat diperoleh genotipe-genotipe yang dapat beradaptasi baik di lingkungan tertentu dan berdaya hasil stabil pada beberapa lingkungan. Penelitian ini bertujuan untuk mendapatkan galur padi gogo yang memiliki potensi hasil tinggi dan stabil pada lingkungan yang luas, serta memiliki keragaan tanaman yang ideal sebagai varietas padi gogo berdaya hasil tinggi. Pengujian stabilitas daya hasil padi gogo dilaksanakan di delapan lokasi pada musim hujan (MH) bulan Oktober 2010 sampai dengan April 2011. Lokasi pengujian tersebar di Jawa dan Sumatera, yaitu : Kebun Percobaan Taman Bogo – Lampung, Natar – Lampung, Kebun Percobaan Cikarawang Bogor – Jawa Barat, Sukabumi – Jawa Barat, Indramayu – Jawa Barat, Purworejo – Jawa Tengah, Wonosari – DI Yogyakarta, dan Malang – Jawa Timur. |
