The objective of this study was to estimate and evaluate the general and specific combining abilities of hybrid combinations for energy biomass production, adopting the methodology of Griffing as adapted by Geraldi and Miranda Filho in evaluation cuts referring to two periods, the wet and dry seasons, and in relation to total dry matter yield (TDMY). The experiment was conducted at Pesagro Rio, located in Campos dos Goytacazes, RJ, Brazil, in a randomized block design with three replicates. Crosses were performed in a partial diallel system. Treatments consisted of 10 parents, 25 hybrid combinations, and 1 control. Three evaluation cuts were made: two in the wet season and one in the dry season. The following traits were evaluated: plant height, stem diameter, leaf width, number of tillers, percentage of dry matter, dry matter yield, and TDMY. Regarding the general combining ability effects, the parents "Cameroon-Piracicaba" and "Mercker" showed outstanding positive values. Of the hybrid combinations, "Cubano Pinda""Mercker", "Cameroon-Piracicaba""Três Rios", "Cameroon-Piracicaba""Mercker 86-México", "IAC-Campinas""Três Rios", "IAC-Campinas""Mercker 86-México", and "Guaçu IZ.2""Roxo" showed superior productive performance. Hybrids can be obtained with superior energy biomass production to that of the currently available elephant grass cultivars.

“…To meet the demands of producers of charcoal from elephant grass, varieties adapted to the different ecosystems, to generate biomass production, are greatly sought. Characteristics such as faster growth, high yield, high energy efficiency, efficient mineral nutrient use, more uniform distribution of the dry matter production throughout the year, and less or more resistance to pests and diseases are used to discriminate between promising genotypes (Menezes et al, 2015;Santos et al, 2014).…”

Elephant grass has been proposed for the energy sector as a possible source of renewable energy, because of its high biomass production. The aim of this study was to evaluate the effect of the mineral nutrients nitrogen and potassium on the morpho-agronomic traits (dry mater yield (DMY), percentage of DM (%DM), number of tillers per linear meter (NT), plant height (PH), stem diameter (SD) and leaf blade width (LW)) in different elephant grass genotypes in a randomized-block experimental treatment in a split-plot arrangement with three replications, in which the genotype factor ('Cuban Pinda'-G1; 'IAC Campinas'-G2; and 'Cameroon'-G3) was randomized in the plot, and the N and K factor was randomized in the sub-plot. The increase in nitrogen and potassium doses utilized influenced very little or almost did not influence the response of the three genotypes for the different morpho-agronomic traits assessed. The three genotypes had high number of tillers, height, and stem diameter at the lowest N and K doses, demonstrating a possible trend of high doses not providing a highly significant increase in these traits. The study of DMY showed that under a low nitrogen dose and with increase in potassium concentrations, dry matter yield increased; however, as the nitrogen dose increased in associated with potassium doses, dry matter yield did not augment, but was rather suppressed. The three elephant grass genotypes: 'Cuban Pinda', 'IAC Campinas', and 'Cameroon', had average dry yields of 52.66, 50.60, and 48.57 t ha-1 , respectively. Results are highly promising and prove the possibility of using elephant grass as an alternative source for biomass production.

“…The knowledge of variability and genetic diversity among genotypes within a germplasm bank allows the identification of parents that, when crossed, generate a greater heterotic effect (Cruz et al, 2012). Menezes et al (2015) crossed genetically divergent elephant grass genotypes and obtained six hybrids with potential for use in elephant grass breeding programs for energy production.…”
