The
genetic relationships among 14 Turkish pepper (Capsicum
annuum L) genotypes, 6 of them inbred lines, were
determined by comparing their molecular traits. The
taxonomic relationships and genetic variation among these
genotypes were investigated with those of 5 foreign pepper
genotypes.
Fifty-six (26%) polymorphic AFLP markers out of total 215 DNA
fragments from 4 primer pairs were used to define the
genetic similarity among the pepper genotypes by dendrograms
or two and three dimensional scaling. Two genotype-specific
markers for the genotype PM-702 were among the polymorphic
ones. The inbred lines of

were partitioned to similar clusters and constituted
extremely low genetic variation. On the other hand, other
local Turkish genotypes had comparatively higher genetic
diversity.
