Chrysanthemum (Chrysanthemum morifolium) is one of the most important ornamental plants which plays a significant role in the development of gardening industry in the world. The knowledge of genetic diversity is one of the prerequisite criteria for Chrysanthemum breeding with important economic goals. Molecular markers have a significant share in elucidation of inter and intra species genetic d...

Annual medics are used for hey production, soil protection, biological fixation of N2 and green manure. In the present study, the inter and intra specific genetic diversity and relatedness of 4 diploid and two tetraploid (M. rugosa and M. scutellata) annual medics were evaluated using microsatellite markers. PCR analysis was performed on genomic DNA from individual plant and PCR products were d...

Hot pepper (Capsicum spp.) is an economically important spice widely cultivated and consumed in Ethiopia. In spite of its wide importance, there is no information available on the molecular genetic diversity of this crop. Cultivars characterization is an important link between the conservation and utilization of plant genetic resources in various breeding programs. Using five ISSR prim...

Determining the level of genetic diversity and relationships among genotypes is foundation for identifying the appropriate parents in different breeding objects. In present study, the genetic diversity of 22 wheat cultivars were tested using 22 pairs of SSR primers. Out of 24 detected alleles, 11 were able to show desirable polymorphism. In average 2.18 alleles per locus were generated, in whic...

The coasts of Imam Khomeini port are one of the most important hot spots of mangrove plantations across Iranian coast of Persian Gulf and Sea of Oman, so this is very important to conserve this valuable ecosystem. For this purpose, 75 individual from 3 populations, keeping the minimum distance of 30 to 50 meters from each other, has been collected and investigated using 15 ISSR markers. This st...

in this study, genetic diversity of 30 accessions of the fennel from different cities of iran and other asian and european countries were assessed by using 20 selective aflp primers. totally, from 1127 observed bands, 250 bands were polymorph. e11-m20 primer with 20 bands, also e46-m35 and etg-m20 primers with 8 bands indicated the maximum and minimum numbers of polymorphism, respectively. acco...

Narrow genetic variability may lead to genetic vulnerability of field crops against biotic and abiotic stresses which can cause yield reduction. In this study a set of 37 wheat microsatellite markers linked with identified QTLs for salinity tolerance were used for the assessment of genetic diversity for salinity in 30 promising lines of hexaploid bread wheat (Triticum aestivum L.). A total of 4...
