Abstract

The aim of this study was to evaluate the Per se performance of elephant grass hybrids obtained by partial diallel crossing and also their parents for energy purposes through agronomic traits during rainy and dry seasons. The experiment was conducted at Pesagro experimental station, Campos dos Goytacazes, RJ, Brazil, in randomized blocks, with three repetitions. The crosses were made between contrasting parents in a partial diallel scheme with 5 female parents x 5 male parents. The treatments consisted of ten parents, twenty-five hybrid combinations and the control. Three cuts were realized for evaluations (April and October 2013 and April 2014). The characteristics evaluated were: plant height (ALT), in m; stem diameter (SD), in cm; leaf blade width (LB), in cm; number of tillers per linear meter (NP); dry matter percentage (%DM) and dry matter production (DMP), in t.ha-1. Variance analysis were performed and the means were grouped according to Scott-Knott test (P <0.05). It was oberved that the hybrid H4 (Cuban Pinda x Taiwan A-144), H7 (Cameroon - Piracicaba x Três Rios), H8 (Cameroon - Piracicaba x Mercker 86-Mexico), H10 (Cameroon - Piracicaba x Roxo), H13 (P241-86-Piracicaba x Mercker 86-Mexico), H17 (IAC Campinas x Três Rios) and H18 (IAC-86-Campinas x Mercker 86-Mexico) presented high biomass production.
