Abstract: With diallel mating design,crosses were made between 8 inbreds tostudy genetic parameters of corn leaf length,width,area,angle and leaf orientation value(LOV).The results showed that characters studied,except leaf area,were controlled by the additivedomfinance genetic system.The additive effect played aw important role for leaf angle and LOV.Andfor leaf length,width and area,it was the dominant effect that played an important role.Low values of leaf angle and LOV were partially dominant and high values of leaf length and width hadsuperdominance.The narrow inheritability of leaf angle was the highest(88.79%).The value ofleaf area was the lowest.
