Combining ability of elephant grass based on nutritional characters
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 ra...
