KERAGAAN KARAKTER AGRONOMI DAN STABILITAS HASIL PADI GOGO PADA SEMBILAN LOKASI PERCOBAAN

ABSTRACT: Information on agronomic characters, adaptability and yield stability of upland rice is important to know to determine which line have high and stable yield on the entire location. This study aims to evaluate the phenotype, adaptability and yield stability of some upland rice promising lines. The research was conducted at nine locations, i.e. Lampung, Sukabumi, Indramayu, Banjarnegara, Blora, Pacitan, Banyumas, and Sitiung at the Wet Season (WS) 2011. The material used consists of 14 lines, i.e. TB490H-MR-4, MR-B11579E-7-1-1, B11584E-MR-5-2-3-1-2, TB356B-TB 47-3, TB363B -MR-25-1-1, B11597C-TB-2-24-1, B11178G-TB-29, TB-TB393C-2-2-2, B12151D-MR-4, MR-48-B11593F, B11942F-TB -12, B11592F-MR-2-3-1, and Situpatenggang and Limboto as check varieties. Each line was grown on a plot size of 4.2 m x 4.8 m using a randomized complete block design (RCBD) in four replication, with 30 cm x 15 cm spacing, each hole consist of 3-5 seedlings. The lines had an average plant height higher and long age period than Limboto and Situpatenggang. The average number of productive tillers, number of filled grain and 1000 grain weight were not significantly different. B12151D-MR-4, MR-B11584E-5-2-3-1-2, TB363B-MR-25-1-1, and B11178G-TB-29 lines has high yield; 4.57 t/ha, 4.16 t/ha, 4.09 t/ha, and 4.08 t/ha, respectively. TB409H-MR-4 has wide adaptability, while TB356B-TB-47-3 and B11597C-TB-2-24-1 was poorly adapted lines.
