Abstract: Marigold merupakan tanaman hias dengan bentuk, ukuran, dan warna yang menarik sehingga berpotensi untuk dikembangkan. Upaya meningkatkan keragaman genetik tanaman marigold Sudamala Barak dilakukan melalui induksi mutasi menggunakan mutagen kimia orizalin. Penelitian ini bertujuan memperoleh nilai LC50 serta konsentrasi dan lama perendaman yang efektif dalam menginduksi keragaman. Penelitian dilaksanakan di Kebun Percobaan IPB Pasir Sarongge pada Februari–Juni 2025 menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan tiga ulangan. Faktor pertama adalah konsentrasi orizalin: 0 ppm (C0), 50 ppm (C1), 100 ppm (C2), 150 ppm (C3), dan 200 ppm (C4). Faktor kedua adalah lama perendaman yaitu 12 jam (T1) dan 24 jam (T2). Nilai LC50 marigold Sudamala Barak adalah 244,25 ppm (12 jam) dan 167,95 ppm (24 jam). Konsentrasi 200 ppm memberikan hasil terbaik karena berpengaruh pada karakter tingkat kehijauan daun, umur berbunga, diameter bunga, dan jumlah mahkota bunga. Lama perendaman 24 jam memberikan hasil terbaik karena berpengaruh pada karakter tingkat kehijauan daun dan jumlah mahkota bunga.
Marigold was an ornamental plant with attractive shape, size, and color so that it had great potential for further development. Efforts to increase the genetic diversity of Sudamala Barak marigold were carried out through mutation induction used chemical mutagens oryzalin. This study aimed to determine the LC50 value and the effective concentration and soaking duration of oryzalin that can induce the diversity of Sudamala Barak marigolds. This study was conducted at the IPB Pasir Sarongge Experimental Garden from February–June 2025 using a Randomized Complete Block Design (RCBD) with three replications. The first factor was oryzalin concentration: 0 ppm (C0), 50 ppm (C1), 100 ppm (C2), 150 ppm (C3), and 200 ppm (C4). The second factor was the soaking time: 12 hours (T1) and 24 hours (T2). The LC50 value of Sudamala Barak marigold were 244,25 ppm (12 hours) and 167,95 ppm (24 hours). The concentration of 200 ppm gave the best results, significantly influencing leaf greenness, flowering time, flower diameter, and the number of flower petals. The soaking duration of 24 hours was found to be the most effective, particularly affecting leaf greenness and the number of petals.
