Abstract：SSR molecular marker technique was used to assess the DNA fingerprint classification and
genetic relationship of 72 melon germplasm resources and breeding materials. From 20 pairs of SSR primers，
76 polymorphic bands were generated. On average each pair of primers produced 3.8 bands．The clustering
result divided the 72 melon germplasm resources into 7 groups．There were 64 accessions in guoup I，
including Xinjiang local resources and almost all of the self bred melon germplasm resources．This means
that the genetic background of Xinjiang muskmelon germplasm res ources is comparatively narrow.
