| Judul Artikel | PENAMPILAN KARAKTER AGRONOMI POPULASI F2 HASIL PERSILANGAN PADI PANDANWANGI × INPARI 48 DAN KEERATAN HUBUNGANNYA DENGAN HASIL |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan mengevaluasi penampilan karakter agronomi populasi F2 hasil persilangan Pandanwangi × Inpari 48, mengidentifikasi karakter yang berhubungan dengan bobot gabah per rumpun, serta memperoleh individu F2 berpotensi unggul. Penelitian dilaksanakan pada Juli 2025–Januari 2026 di screenhouse Fakultas Pertanian Universitas Jenderal Soedirman. Sebanyak 71 individu F2 dievaluasi menggunakan Rancangan Acak Kelompok (RAK) augmented dengan varietas pembanding. Karakter yang diamati meliputi tinggi tanaman, umur berbunga, jumlah anakan total, jumlah anakan produktif, panjang malai, jumlah gabah per malai, persentase gabah isi, bobot 1.000 butir, bobot gabah per rumpun, dan sifat aromatik. Data dianalisis dengan ANOVA 5%, uji Least Significant Increase (LSI) 5%, korelasi, dan analisis sidik lintas. Genotipe berpengaruh sangat nyata terhadap tinggi tanaman, umur berbunga, jumlah gabah per malai, bobot gabah per rumpun, dan bobot 1.000 butir, serta berpengaruh nyata terhadap persentase gabah isi dan sifat aromatik. Bobot gabah per rumpun berkorelasi positif dengan persentase gabah isi (0,41), panjang malai (0,37), dan jumlah gabah per malai (0,55), serta negatif dengan umur berbunga (−0,41). Jumlah gabah per malai dan persentase gabah isi memberikan pengaruh langsung terbesar, masing-masing 0,4203 dan 0,3195. Berdasarkan kombinasi bobot gabah per rumpun, umur berbunga, dan sifat aromatik diperoleh 10 individu F2 terpilih, yaitu E5, E3, E27, E16, E15, E53, E2, E34, E4, dan E23. |
| Abtrak (Bhs. Inggris) | This study evaluated agronomic character performance of an F2 population derived from the Pandanwangi × Inpari 48 rice cross, identified agronomic characters associated with grain weight per hill, and obtained potentially superior F2 individuals. The study was conducted from July 2025 to January 2026 in the screenhouse of the Faculty of Agriculture, Jenderal Soedirman University. Seventy-one F2 individuals were evaluated using an augmented randomized complete block design with comparison varieties. Characters observed included plant height, flowering time, total tillers, productive tillers, panicle length, grains per panicle, filled-grain percentage, 1,000-grain weight, grain weight per hill, and aroma. Data were analyzed using 5% ANOVA, 5% Least Significant Increase (LSI), correlation, and path analysis. Genotype effects were highly significant for plant height, flowering time, grains per panicle, grain weight per hill, and 1,000 grain weight, and significant for filled-grain percentage and aroma. Grain weight per hill was positively correlated with filled-grain percentage (0.41), panicle length (0.37), and grains per panicle (0.55), but negatively correlated with flowering time (−0.41). Grains per panicle and filled-grain percentage had the largest direct effects on grain weight per hill, with coefficients of 0.4203 and 0.3195, respectively. Selection based on grain weight per hill, flowering time, and aroma identified ten F2 individuals: E5, E3, E27, E16, E15, E53, E2, E34, E4, and E23. |
