Abstract: Early yield is the main character for evaluating early maturity of eggplant in agricultural production. This study aims to explore early maturing related characters of eggplant, thus to assist early maturing breeding. 138 cross combinations of purple round eggplant were used as materials for the correlation and path analysis of main characters that formed the early yield of eggplant in 2012, 2013 and 2014. The results showed that the early yield per plant had extremely significant relationship with the fruit number and the fruit weight. However the first flower nod had limited effect and showed no steady correlation with the early yield per plant. The path coefficients of the fruit number and the fruit weight to the early yield per plant in 2014 were 1.2073 and 0.7935, which showed that the fruit number and the fruit weight were main factors that directly influenced the early yield per plant. So the fruit number and big fruit with intense flesh rather than the first flower nod could be major characters for breeding new eggplant cultivars with high early yield.
