| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk: 1) mengkaji pengaruh kondisi lahan aerob dan anaerob terhadap indeks panen dan sistem perakaran sepuluh galur padi tipe baru, 2) mengkaji respon galur padi tipe baru terhadap kondisi lahan aerob dan anaerob, dan 3) mengkaji korelasi antara karakter agronomik dan hasil. Penelitian telah dilaksanakan dengan menggunakan percobaan pot di Screen House, Fakultas Pertanian, Universitas Jenderal Soedirman selama 6 bulan dari bulan September 2014 hingga Maret 2015. Rancangan yang digunakan adalah Rancangan Acak Kelompok Lengkap (RAKL) dengan 3 kali ulangan. Faktor pertama yaitu sepuluh galur padi tipe baru. Faktor kedua yaitu kondisi lahan anaerob (A1) dan kondisi lahan aerob (A2). Variabel penelitian yang diamati adalah panjang akar (cm), bobot basah akar (g), volume akar (ml), bobot kering akar (g), bobot kering tajuk (g), bobot gabah per rumpun (g), dan indeks panen. Hasil penelitian menunjukkan bahwa: 1) Nilai indeks panen tinggi pada kondisi lahan aerob adalah G4 (16-4-3-(6-4-2) dan nilai indeks panen tinggi pada kondisi lahan anaerob adalah G6 (4-4-5-(2-4-5). Sistem perakaran yang menunjukkan daya adaptasi tinggi adalah G3 (5-7-4-3-3). Kondisi lahan anaerob berpengaruh untuk meningkatkan bobot basah akar, volume akar, bobot kering tajuk, dan bobot gabah per rumpun, 2) Respon galur padi tipe baru terhadap kondisi lahan aerob dan anaerob memberikan pengaruh nyata pada bobot kering akar adalah G1 (5-7-3-3-3), G3 (5-7-4-3-3), G7 (16-4-2-(5-4-6), dan G8 (21-4-2-(18-4-2), dan 3) Korelasi antara bobot kering tajuk dan bobot gabah per rumpun, bobot kering akar dan bobot gabah per rumpun, serta volume akar dan bobot gabah per rumpun menunjukkan pengaruh nyata dan positif. |

| Abtrak (Bhs. Inggris) | This research aimed to: 1) assess the effect of aerobic and anaerobic soil conditions on harvest index and root system of ten lines new-type rice, 2) assess the response of the lines of a new-type rice at aerobic and anaerobic soil conditions, and 3) assess the correlation between agronomic characters and yield. The research has been conducted using pot experiment in Screen House, Faculty of Agriculture, Jenderal Soedirman University, for 6 months start from September 2014 to March 2015. The design of this research was Randomized Block Design Complete (RBCD) with 3 repetitions. The first factor was ten lines of new-type rice. The second factor was anaerobic soil conditions (A1) and aerobic soil conditions (A2). The research variables measured were root length (cm), root-wet weight (g), root volume (ml), root-dry weight (g), canopy-dry weight (g), grain weight per clump (g), and harvest index. The results showed that: 1) The high of harvest index on aerobic soil conditions was G4 (16-4-3-(6-4-2) and the high of harvest index on anaerobic soil conditions was G6 (4-4-5-(2-4-5). The root system with high adaptability was G3 (5-7-4-3-3). Anaerobic soil conditions could increase the root-wet weight, root volume, canopy-dry weight, and grain weight per clump, 2) Response of the lines on aerobic and anaerobic soil conditions that gives significant effect on root dry weight was found in G1 (5-7-3-3-3), G3 (5-7-4-3-3), G7 (16-4-2-(5-4-6), and the G8 (21-4-2-(18-4-2), and 3) Correlations between canopy dry weight and grain weight per clump, root-dry weight and grain weight per clump, as well as root volume and grain weight per clump had shown the significant effect and positive. |
