Abstract: To p robe into the genetic resistant law to bacterialwilt (BW) in eggp lant, the genetic studies to BW of 064 (Beijing six-leaf eggp lant) , S3 ( highly resistant half-cultivated species of Malasia) and 064 ×S3 F2 populations is carried out on RAPD marker. 300 decamer p rimerswith arbitrary sequences are chosen for
polymerase chain reaction amplication. It is found that the polymorphism between the parents could be detected by 15.6% of the primer; one RAPD marker S264780 ( the sequence of the primer: CAGAAGCGGA) tightly links to the resistance gene of S3 with the overcross value of 4.32% and genetic distance of 4.33 cM.

Key words: Solanum melongena, Bacterial wilt resistance gene, RAPD
