Abstract Robusta coffee ( Coffea Canephora ) is an important source of income and employment, contributing significantly to the economies many developing countries. This species split into two genetic groups: Guinean Congolese. Côte-d’Ivoire primary diversification center pool, which offers great potential for improvement.

Epistasis has been shown to have an important role in the genetic control of several quantitative traits in the common bean. This study aimed to investigate the occurrence of epistasis in intra- and inter-pool gene crosses of the common bean. Four elite lines adapted to Brazilian conditions were used as parents, two from the Andean gene pool (ESAL 686; BRS Radiante) and two from the Mesoamerica...
