| Abstract: | Sorgum (Sorghum bicolor [L.] Moench) merupakan tanaman asli Afrika Timur. Tanaman sorgum memiliki potensi besar untuk dikembangkan sebagai bahan pangan, pakan, bioetanol, dan berbagai industri lain. Produktivitas sorgum saat ini masih tergolong rendah dan perlu upaya peningkatan melalui perakitan varietas unggul. Penelitian ini bertujuan mengevaluasi populasi F3 hasil persilangan Demak 4 x Soraya 3 sehingga diperoleh informasi keragaman genetik, karakter agronomi, dan komponen hasil. Penelitian dilaksanakan pada Mei 2024 hingga September 2024 di Kebun Percobaan Muara IP2TP, Bogor. Bahan yang digunakan adalah 457 genotipe uji F3 Demak 4 x Soraya 3, tetua Demak 4, dan tetua Soraya 3 sebagai pembanding yang ditanam menggunakan metode Single Seed Descent (SSD). Hasil penelitian menunjukkan keragaman karakter agronomi dan komponen hasil yang tinggi. Karakter yang diamati dikendalikan melalui aksi gen epistasis dan aditif. Nilai heritabilitas menunjukkan kategori tinggi – sedang, nilai heritabilitas rendah hanya pada karakter panjang rachis. Karakter yang berkorelasi kuat dan signifikan dengan hasil sorgum adalah bobot kering malai dan diameter malai (0,97 dan 0,74). Terdapat 46 genotipe tanaman yang diduga sebagai segregan trangresif dengan bobot biji per malai (61 – 132 g). Genotipe DS139 merupakan genotipe paling unggul dengan bobot biji per malai tertinggi (132,61 g) dan bobot kering malai tertinggi (155,27 g). / Sorghum (Sorghum bicolor [L.] Moench) is native to East Africa. Sorghum plants have great potential to be developed as food, feed, bioethanol, and various other industries. Sorghum productivity is currently still relatively low and needs to be increased through the assembly of superior varieties. This study aims to evaluate the F3 population of Demak 4 x Soraya 3 cross to obtain information on genetic diversity, agronomic characters, and yield components. The research was conducted from May 2024 to September 2024 at Muara IP2TP Experimental Farm, Bogor. The materials used were 457 F3 test genotypes of Demak 4 x Soraya 3, Demak 4 elders, and Soraya 3 elders as a comparison planted using the Single Seed Descent (SSD) method. The results showed a high diversity of agronomic characters and yield components. The observed characters were controlled through epistasis and additive gene action. Heritability values showed high - medium category, low heritability value only on rachis length characters. Characters that were strongly and significantly correlated with sorghum yield were panicle dry weight and panicle diameter (0.97 and 0.74). There were 46 genotypes suspected to be transgressive segregants with seed weight per panicle (61 - 132 g). Genotype DS139 was the most superior genotype with the highest seed weight per panicle (132.61 g) and the highest panicle dry weight (155.27 g). |
