The interaction between genotypes and environment (GxE) can influence the selection process and recommendation of peanut cultivars. The objective of this study was therefore to evaluate the influence of GxE interaction of peanut pod yield using AMMI. The yield of 18 peanut lines and the cultivars IAC Caiapo and Runner IAC 886 was assessed in 10 field trials in the state of São Paulo. Significant effects of genotypes, environments and GxE interactions were detected in the analysis. The first AMMI principal component (IPCA1) explained 42.3% of the sum of squares of the GxE interaction. Sixteen of the twenty lines/cultivars under evaluation presented medium to high stability. Genotypes L127, L118, L123 line and Runner IAC 886 accounted for the greatest part of GxE interaction. Lines L132, L149 and L1-50P presented the highest stability and pod yields, above the overall mean, reflecting outstanding potential for cultivar recommendation. |
