Uji Daya Hasil Pendahuluan Beberapa Galur Mutan Padi Gogo Towuti di Lahan Kering

Abstract

Kebutuhan pangan terus meningkat setiap tahun seiring bertambahnya jumlah penduduk di Indonesia. Sebagai upaya diversifikasi produksi, perhatian terhadap budidaya padi gogo semakin meningkat guna mendukung ketahanan pangan di lahan suboptimal. Penelitian ini bertujuan untuk melihat keragaan agronomi dan daya hasil dari 10 galur mutan padi gogo Towuti di lahan kering. Penelitian ini dilaksanakan pada bulan November 2024 – Maret 2025 di Kebun Percobaan Kawasan Sains dan Teknologi (KST), GA. Siwabessy, Badan Riset dan Inovasi Nasional (BRIN), Lebak Bulus, Jakarta Selatan. Genotipe yang digunakan dalam penelitian ini adalah 10 galur mutan yaitu GMT01, GMT02, GMT03, GMT04, GMT05, GMT06, GMT07, GMT08, GMT09, GMT10 dan 2 varietas pembanding yakni varietas Towuti (Induk) dan Limboto (Varietas padi gogo nasional). Rancangan percobaan yang digunakan adalah rancangan RKLT dengan faktor tunggal berupa genotipe dengan tiga ulangan. Perbedaan antar perlakuan dianalisis melalui uji lanjut Beda Nyata Jujur (BNJ). Hasil penelitian menunjukkan bahwa produktivitas galur-galur mutan uji tidak berbeda nyata dibandingkan varietas Towuti dan Limboto. Galur-galur mutan uji memiliki hasil yang sama dengan varietas Towuti dan Limboto, yang memiliki produksi hasil tinggi di lahan kering. Empat galur mutan yaitu GMT05, GMT06, GMT07, dan GMT10 memiliki produksi hasil dan komponen hasil tinggi sehingga berpotensi dikembangkan lebih lanjut sebagai varietas unggul baru padi gogo.

The increasing demand for food each year follows the population growth in Indonesia. As part of production diversification, attention to upland rice cultivation is increasing to support food security on suboptimal lands. This study aims to evaluate the yield potential of ten mutant lines of upland rice (Towuti) under dry land conditions. The research was conducted from November 2024 – March 2025 at the Experimental Field of the Science and Technology Area (KST), GA. Siwabessy, National Research and Innovation Agency (BRIN), Lebak Bulus, South Jakarta. The tested genotypes included 10 mutant lines: GMT01, GMT02, GMT03, GMT04, GMT05, GMT06, GMT07, GMT08, GMT09, GMT10, along with two check varieties, Towuti (parent) and Limboto (national upland rice variety). The experimental design employed a randomized complete block design (RCBD) with a single factor (genotype), repeated three times. Differences between treatments were analyzed using the Honest Significant Difference (HSD) test. The results indicate that the yield productivity of the tested mutant lines did not differ significantly from the check varieties Towuti and Limboto. The results indicated that the yield of the mutant lines was not significantly different from that of Towuti and Limboto. Four lines, GMT05, GMT06, GMT07, and GMT10, produced high yields with favorable yield-related traits, suggesting the potential for development as high-yielding upland rice cultivars
