Genetic diversity of 30 common vetch (Vicia sativaL.) lines and cultivars obtained from various resources or collected from natural flora of Turkey was evaluated by using 55 sequence-related amplified polymorphism (SRAP) and five inter-simple sequence repeat (ISSR) primer sets, and their nuclear DNA contents were determined by flow cytometer. A total of 188 polymorphic loci were detected, with an average of 3.62 loci per primer. The percentage of polymorphic loci was 82.1%. The polymorphism information content values ranged from 0.12 to 0.96, with an average of 0.63. The genetic distance coefficients were in the range of 0.112–0.627. Cluster analysis revealed that the 27 lines and three cultivars could be divided into two main groups. No polyploidy was detected within any vetch lines tested while significant (P< 0.0001) nuclear DNA content differences were determined. The present study revealed that fast and accurate fingerprinting analysis could be done using SRAP and ISSR markers, which indicated existing significant variation among common vetch lines and cultivars.

Ginger (Zingiber officinale Roscoe) is an economically important plant, valued all over the world. The existing variation among 16 promising cultivars as observed through differential rhizome yield (181.9 to 477.3 g) was proved to have a genetic basis using different genetic markers such as karyotype, 4C nuclear DNA content and random amplified polymorphic DNA (RAPD). The karyotypic analysis revealed a differential distribution of A, B, C, D and E type of chromosomes among different cultivars as represented by different karyotype formulas. A significant variation of 4C DNA content was recorded in ginger at an intraspecific level with values ranging from 17.1 to 24.3 pg. RAPD analysis revealed a differential polymorphism of DNA showing a number of polymorphic bands ranging from 26 to 70 among 16 cultivars. The RAPD primers OPC02, OPA02, OPD20 and OPN06 showing strong resolving power were able to distinguish all 16 cultivars. The extent of genetic diversity among these cultivars was computed through parameters of gene diversity, sum of allele numbers per locus and Shannon’s information indices. Cluster analysis, Nei’s genetic similarity and genetic distances, distribution of cultivars into special distance classes and principal coordinate analysis and the analysis of molecular variance suggested a conspicuous genetic diversity among different cultivars studied. The genetic variation thus detected among promising cultivars of ginger has significance for ginger improvement programs.
