Abstract: Genomic DNAs from‘Red Sun’kiwifruit and its sport red-fleshed kiwifruit were amplified by RAPD with 300 102bp random primers to study the genetic substance change of the sport . Among the primers most amplification products were monomorphic , only ten of which could generate polymorphic segments. 20 out of the 148 amplified fragments were distinctive including the loss of a normal segment , appearance of a new segment and intensity changes. The Nei’s association coefficient and genetic distance between them were 0.7619 and 0.1429 respectively. The differences of amplified DNA segments showed that the red-fleshed sport was related to changes of some genetic substances. The polymorphic segments could be used to forecast the flesh color of grafted seedlings from the sport scion
