Orchardgrass is a highly variable, perennial forage grass that is cultivated throughout temperate and subtropical regions of the world. Despite its economic importance, the genetic relationship and distance among and within cultivars are largely unknown but would be of great interest for breeding programs. We investigated the molecular variation and structure of cultivar populations, comp...

the genetic diversity of 40 tobacco (nicotiana tabacum l.) cultivars was analyzed using 12 issr primers. thecultivars were evaluated for 14 traits using a simple lattice design (7×7) with two replications. of 149 amplified bands, 142 (95.3%) were polymorphic. maximum and minimum bands were generated by primers ubc825 (17 bands and 94.11% polymorphic) and ubc824 (7 bands and 100% polymorphic), r...

Genetic resources are the most valuable national treasure of countries, being vital to identify, conserve and use them. The Persian Walnut (Juglans regiaL.), a diploid species native to the mountainous regions of Central Asia, is the major walnut species cultivated for nut production and one of the most widespread tree nut species in the world. This research was conducted in M...

Glaciation and mountain orogeny have generated new ecologic opportunities for plants, favoring an increase in the speciation rate. Moreover, they also act as corridors or barriers for plant lineages and populations. High genetic diversity ensures that species are able to survive and adapt. Gene flow is one of the most important determinants of the genetic diversity and structure of out-crossed ...

Genetic analysis of 56 samples of Jatropha curcas L. collected from Thailand and other countries was performed using the methylation-sensitive amplification polymorphism (MSAP) technique. Nine primer combinations were used to generate MSAP fingerprints. When the data were interpreted as amplified fragment length polymorphism (AFLP) markers, 471 markers were scored. All 56 samples were cla...

association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. this study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. this investigation was performed using 77 barley genotypes and aflp markers. in phenotypic evaluation, reaction of seedlings to powdery mild...

it is important to identify the genetic diversity and phylogenic relationships for achieving desirable citrus cultivars. in present investigation rapd markers were used to determine genetic diversity among 29 citrus genotypes. from 19 used primers, 248 polymorphic bands were amplified. primers opa-07 and opa-05 (with 19 and 8 amplified bands), produced maximum and minimum polymorphic bands, res...
