Rice is the main food crop for most of the world's population. This research aims to obtain information on the influence of genotype interactions with the environment on potential grain yield characteristics and to obtain genotypes that have stability and adaptability to suboptimal environments. The research was carried out in March–July 2023 at Polinela Organic Farm. The experiment used a completely randomized group design (RKTS). Observations were made on the grain yield of 12 rice genotypes grown in three different environments. Statistical analysis using PBSTAT-GE software. There are three genotypes that have good stability based on eight stability analyses, namely Sertani 13 (G5), Inpari 30 (G12), and Trisakti (G6). Sertani 13 (G5) and Inpari 24 (G2) are genotypes with extensive adaptation. Genotypes based on specific environments are Baroma (G8), PTP 01 (G3), and Inpara 8 (G11), which adapt well to organic environments. Sertani 13 (G5) is adaptive to non-organic environments, and Mentik Susu (G4) is adaptive to aquaponic environments. The highest average production obtained based on the environment is non-organic, with an average yield of 5.95 tons/ha. Baroma (G8) is the genotype with the highest average, namely 6.85 tons/ha.
