Abstract: Six eggplant inbred lines with diferent resistance to bacterial wilt were used as parents in this ex—
periment．The populations were evaluated for their reaction to bacterial wilt by artificial inoculation at the seedling
stage．By using Grifing I an d Hayman methods，a 6×6 dialel analysis was done to analyze the variance of the
combining ability and estimate the genetic parameters．It Was suggested that the inheritance of the resistance to bac—
terial wilt in the eggplan t fit to the ‘additive—dominant’ model，additive efect，dominant efect an d reciprocal effect
all p|ayed a role in the genetics of the resistance to bacterial wilt in eggplant，but the additive efect Was the
major．The resistance to bacterial wilt in eggplant Was recessive and the susceptibility Was partial dominant．The re—
sistance to bacterial wilt in eggplant Was controlled by a lot of minor genes，several major genes and cytoplasm
genes ·
