Abstract

The objective of the work was to evaluate the effects of general combining ability (CGC) of the parents and specific combining ability (CEC) in the elephant grass hybrids by diallel analysis adapted to partial diallel crosses based on nutritional characters. Sixteen hybrids and eight parents in a randomized block design with three replications were evaluated. The study considered percentage of dry matter (%DM), ash (%ASH), crude protein (%CP) and neutral detergent fiber (NDF). There were significant differences among genotypes for the traits evaluated, with a predominance of dominance gene effect. Based on CGC, the best parents were Taiwan A-144, Vruckwona Africana e Taiwan A-146. The best intersections based on CEC were Taiwan A-144 x Taiwan A-146, Vruckwona Africana x Taiwan A-146, Vruckwona Africana x Mercker S.E.A., Vruckwona Africana x Napier nº2 e Pusa Napier nº2 x Mercker Santa Rita.
