Assessment of Genetic Diversity in Cucumber (Cucumis sativus L.) Genotypes Using Morphological Characters and AFLP Analysis
Abstract
For
this purpose, 18 cucumber lines were
evaluated for their genetic diversity using six morphological characterizations
(plant morphology, plant length, length of leaf blade, fruit length, fruit
diameter and fruit stem length) and eight AFLP markers. These AFLP primer combinations
amplified well and also showed polymorphism. Thus, 1975 AFLP fragments were
obtained and 1468 fragments were polymorphic (75.34%). Dendrograms were drawn
using UPGMA (Unweighted Pair Group Method) arithmetical averages and according
to the UPGMA dendrogram, the cucumber accessions clustered into two main
groups. The genetic distances of the dendrogram varied between 0.92 and 0.96. Cluster analysis based on morphological
data discriminated all lines into three major clusters in UPGMA
dendrogram. The
similarity coefficient ranged between 0.888
and 0.982 indicating that the
cucumber lines used in the study have a low level of genetic variation. Results
obtained from the phylogenetic dendrogram by 8 pairs of AFLP primers were
consistent with those from the UPGMA clustering analysis, which were in
according with the morphological taxonomy on cucumber.
