This study evaluated the genotype by environment interaction of 14 sweet corn varieties and 2 check varieties grown in 4 locations in West Java, Indonesia. Analysis of variance showed that environmental effects had the greatest influence on yield, followed by genetic effects. AMMI analysis indicated that the first component explained 81.44% of the genotype by environment interaction sum of squares. A biplot identified genotypes that performed best in specific locations as well as stable genotypes that were high-yielding across locations. Several genotypes were identified as stable and widely adaptable, making them suitable for commercial production.
