<![CDATA[Curcuma aeruginosa Roxb. rhizome is an essential herb material with significant antimicrobial, anticancer, and antioxidant activities. Thus, it is important to search for C. aeruginosa plant that has the rhizome yield trait with more excellent stability in changing environmental situations. This research aimed to evaluate the genotype x environment interaction using additive main effects and multiple interaction (AMMI) analysis for photosynthetic rate and rhizome yield of C. aeruginosa genotypes. Twenty clones of C. aeruginosa plus three control varieties of C. zanthorrhiza Roxb. were evaluated in three environments (Bogor, Cianjur, and Sukabumi) using a randomized complete block design with three replicates. The photosynthetic rate and rhizome yield showed significantly (p < 0.01) genotype x environment interaction. The AMMI2 explained 100% variability of the photosynthetic rate and rhizome yield parameters. G2, G10, G12, G13, G14, G16, G17, G19, and G20 were stable genotypes for rhizome yield based on AMMI analyses. Meanwhile, the stable genotype in photosynthetic rate recorded in G4, G5, G6, G8, G11, G13, and G14. Keywords: AMMI, genotypes, multilocation trials, pink and blue ginger, varieties]]>
