Conteúdo: 	The elephant grass (Pennisetum purpureum) is a tropical perennial forage plant with high biomass production that adapts to various soil and climatic conditions in Brazil. Stability is defined as the consistency in performance of genotypes in different environments. The aim of the present study was to estimate stability parameters by the Eberhart and Russel method, and to select elephant grass genotypes with forage production stability and high-yield in Campos dos Goytacazes, RJ, Brazil. Five harvests were made for evaluation in two years. The experimental design was arranged as randomized blocks design, with 80 treatments and two replicates. After the individual analysis of variance for dry matter yield, a combined split-plot analysis was performed. Mean values from each harvest as well as overall means of the genotypes in the five harvests were grouped using the Scott-Knott test (p£0.05). To obtain the estimates of stability over time, the method of Eberhart and Russell was used, considering the genotypes and successive harvests as environments. Genotypes Pasto Panamá, IJ 7136 cv. EMPASC 307, CAC-262, 02 AD IRI, 08 AD IRI, and Gigante de Pinda showed high forage production and phenotypic stability over the five harvests.
