The high degree of polymorphism of AFLPs provide a efficient system for
identification and genome analysis of sweet cherry cultivars. The cultivars
of sweet cherry have been usually characterized by assessment of phenotypic
and pomological traits. AFLP markers have been employed to identify 142
sweet cherry accessions and estimation the genetic diversity among this
material. 10 of 18 tested primer combinations were informative with up to
80 bands per primer combination, 7-33% of the amplified bands were
polymorphic depends on primer combination. A total of 142 polymorphisms
were revealed in the 142 sweet cherry cultivars. All of the cultivar tested
could be clearly identified. The cluster analysis revealed two distinct
group of cultivars. Some cultivars showed a high degree on similarity. They
might be clones of the same origin or very closed related accessions. AFLPs
provide a means for identification and effective maintenance and
utilization of sweet cherry genetic diversity.
