Abstract

Abstract:

In the present study，the accuracy of the four molecular markers tightly linked with Rgls
locus，S0405127（SSR），S0304673（SSR），SNP4236，and InDel4254 were tested based on the resistant
phenotypic and genotypic identification of 50 apple cultivars. The results indicated that the accuracy of the
four molecular markers were 90%，94%，96%，92%，respectively. The study could provide breeders an
effective method to speed up breeding program by using these molecular markers for the pre-selection of
the hybrid seedlings resistant to the Glomerella leaf spot in apple.

Key words: apple, Glomerella leaf spot, molecular marker, accuracy test
