Abstract

GGE-Biplot method was used to analyze data of iron (Fe) content of 10 rice genotypes evaluted at eight paddy fields during the wet and dry seasons of 2007 – 2008. The objective of this study was to determine the effect of genotype (G) and genotype x environment interaction (GE) on the iron content of 10 rice genotypes. Experiments were conducted using a randomized completely block design with three replications at each environment. Results indicated that environment (E), G and GE had significant effect on rice grain’s iron content. Environment explained 74.43% of the total (G + E + GE) variation, whereas G and GE explained 5.60% and 19.67% of the total variation, respectively. The first two principal components (PC1 and PC2) were used to create a two-dimensional GGE-biplot, and these principal components explained 70.40% and 15.36% of the GGE sum of squares, respectively. Barumun genotype was desirable for its highest iron content, especially in term of ability and stability. Cilongok environment was the best representative of the overall environments and the most powerful environment to discriminate the genotypes.
