Taro is one of the important aroid root crops throughout Southeast Asia. Phenotypic plasticity of taro genotypes in response to waterlogging and drought stress was evaluated based on growth and yield characters to select an adaptive genotype of taro under water stress cultivation. This study aims to evaluate the morphological plasticity of several taro genotypes under water-stress conditions. The study was conducted at Pondok Modern Darussalam Gontor Farm, Siman, Ponorogo, Indonesia. On this research, Dasheen genotype (Bentul, Bentul Ungu, Ketan, Pratama, California, Pari, and Sutra), Eddoe genotype (Satoimo, Ozikawa, Siromi, Jepang Hijau, Jepang Ungu, Dempel, and Dempel Ungu), and Xanthosoma (Talas Hitam, Talas Hijau, and Talas kuning), using a split plot design with three replications. The main plot is waterlogging and dryland cultivation, while the subplot is taro genotypes. Variation of phenotypic coefficient was observed for root fresh weight per plant, corm fresh weight per plant, canopy fresh weight, plant height, number of leaves, and number of stolons. The research shows that plasticity values vary between genotypes and water stress. Ozikawa, Talas Hitam, and Talas Kuning genotypes show relatively stable performance under dry land conditions, while Dempel Ungu tends to be more adaptable to waterlogging conditions. The plasticity score indicates that Bentul Ungu is adaptable to waterlogging and drought conditions.
