Abstract A diallel study among nine parental clones of cassava was conducted in the subhumid environment on northern coast Colombia. Analysis variance suggested significant effects for six variables analysed: fresh‐root yield, harvest index, root dry matter content, height first branching, reaction to thrips and plant‐type scores. General specific combining ability their interaction with were most as well. Results that dominance plays a particularly important role cases yield index but had relatively little importance thrips, content or branching. Specific breeding approaches are these traits, depending relative additive non‐additive inheritance. The correlations different traits also analysed several magnitude reached statistical biological significance.
