      Abstract
      Cabai keriting (Capsicum annuum L.) merupakan salah satu sayuran penting yang diproduksi di Indonesia. Produksi cabai keriting pada tahun 2024 mengalami penurunan dibandingkan pada tahun 2023. Salah satu upaya untuk meningkatkan produksi cabai keriting dapat dilakukan dengan program pemuliaan mutasi tanaman. Penelitian ini bertujuan mendapatkan informasi pengaruh iradiasi sinar gamma terhadap keragaan cabai keriting dan menganalisis keragaman cabai keriting hasil mutasi fisik dengan iradiasi sinar gamma pada beberapa dosis. Penelitian ini dilaksanakan di Kebun Pusat Kajian Hortikultura Tropika (PKHT), Tajur, Kota Bogor dan Badan Riset dan Inovasi Nasional (BRIN), Cilandak, Jakarta Selatan pada bulan Desember 2024 - Juni 2025. Rancangan percobaan yang digunakan adalah Rancangan Kelompok Lengkap Teracak (RKLT) dengan faktor utama yaitu dosis iradiasi sinar gamma sebesar 0 Gray (G0), 75 Gray (G1), 150 Gray (G2), dan 225 Gray (G3). Hasil penelitian menunjukkan iradiasi sinar gamma hanya berpengaruh nyata pada karakter jumlah biji per buah cabai keriting. Nilai koefisien keragaman tertinggi terdapat pada karakter produktivitas tanaman pada dosis 75 Gray dan 150 Gray. Hal tersebut menandakan dosis 75 Gray dan 150 Gray berpotensi memberikan nilai komponen hasil tertinggi pada tanaman cabai keriting.
       
      Curly chili (Capsicum annuum L.) is one of the important vegetables produced in Indonesia. Curly chili production in 2024 decreased compared to 2023. One strategy to increase curly chili pepper production is through a plant mutation breeding program. This study aims to obtain information on the effects of gamma ray irradiation on the performance of curly chili pepper and to analyze the diversity of curly chili peppers resulting from physical mutations induced by gamma ray irradiation at various doses. The research was conducted at the Tropical Horticulture Study Center (PKHT) Experimental Farm, Tajur, Bogor City, and the National Research and Innovation Agency (BRIN), Cilandak, South Jakarta, from December 2024 to June 2025. The experimental design was arranged in a Randomized Complete Block Design (RCBD) with the primary factor being the gamma ray irradiation dose of 0 Gray (G0), 75 Gray (G1), 150 Gray (G2), and 225 Gray (G3). The results showed that gamma ray irradiation significantly affected only the number of seeds per fruit. The highest coefficient of variation values were observed in plant productivity traits at doses of 75 Gray and 150 Gray. This indicates that irradiation doses of 75 Gray and 150 Gray have contributed to providing the highest yield component values for curly chili plants.
