Abstract: The fluorescent labeling of simple sequence repeat with tailed primer M13 was used to
establish fingerprints of 19 apple cultivars suitable for chips and 25 apple cultivars suitable for juice，and
the genetic relationship was discussed by cluster analysis. CH04h02 and CH05d04 can distinguish all of
the processing apple cultivars. The SSR fingerprints of fouty-four apple cultivars are different from each other. The SSR fingerprints of processing apple cultivars established can serve as the cultivars-specific
patterns and as an important basis for cultivars identification. The coefficient of 44 apple cultivars were
0.7259–0.9704. All the cultivars tested were divided at coefficient 0.798. All the apple cultivars suitable
for juice except Rome Beauty，Macoun，Hongyue，Honeycrisp，Stark Jumbo，Rainier，Duanzhi Gold
Delicious were clustered together in the dendrogram. But the apple cultivars suitable for chips were
clustered relatively dispersedly. The processing characteristics of processing apple cultivars with extensive
genetic basis are associated with parent. When we continue to improve and perfect the evaluation system
of quality for apples suitable for juicing and chips，consideration must be given to the correlation between
genetic relationships and processing properties. We should reinforce the use of Gold Delicious，Jonathan，
Ralls，Fuji and Delicious which are good breeding parents of processing apple cultivars.
