Abstract: The genetic relationship s of 38 mango (Mangifera indica L. ) accessions were examined by
ISSR markers. Of the 60 ISSR p rimers screened, only 10 p rimers gave rep roducible, polymorphic DNA ampli
fication patternswith a total 79 of amplified bands. Their percentage of polymorphic band was 86.7%. By
banding patterns obtained from these 10 primers, each accession could be distinguished from the others excep t
either Hongjinlong or Guifei, since the two accessions had the same amplified band patterns. Genetic distances
among the tested accessions ranged from 0 to 0.682 with an average of 0.393. Five group s were formed by
UPGMA clustering and the classification results were discussed in this paper.
