“…This fact is confirmed by observing the mean values of the evaluated traits, where Mercker 86-Mexico obtained high means for the agronomic traits %DM and DWM, while Mercker Pinda México presented higher means for the industrial traits %CEL and %ADF. These results differ from those found in the literature, where a classification of the elephant grass germplasm variability is reported in four morphological groups: Napier, Merker, Cameroon, Anão, and interspecific hybrids (Pereira, 1992), or a division considering clustering results based on molecular analysis with the formation of two groups, where group I is constituted by morphologically closer accesses from the cultivars Napier and Merker, while group II presents greater morphological identification with the cultivar Cameroon (Passos et al, 2005;Pereira et al, 2008). From the results obtained in this study, the genotypes Mercker Pinda Mexico and Mexico-86 Mercker do not belong to the same group where Napier's access based on the biomass quality and morpho-agronomic traits have been allocated.…”
