the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

Random amplified polymorphic DNA (RAPDs) were used to investigate the intraspecific variability among 19 geographic isolates of Globodera tabacum solanacearum from eight counties in Virginia and one county in North Carolina. Globodera tabacum tabacum, G. t. virginiae, and the Mexican cyst nematode (MCN) were included as outgroups. Six primers were used and 119 amplification products were observ...

Ragi or finger millet (Eleusine coracana L.) is an important crop used for food, forage, and industrial products. It is distributed in tropical and temperate regions of the world. The germplasm identification and characterization is an important link between the conservation and utilization of plant genetic resources. Traditionally, species or varieties identification has relied on morphologica...

Construction of a genetic linkage map is necessary to apply marker-assisted selection tools in a crop improvement program. Except for the recent studies from two laboratories, most of the previous studies have shown little or no DNA polymorphism in cultivated groundnut (Arachis hypogaea L.). In the present study, 70 selected genotypes, representing variability for several morphological, physiol...

Molecular markers are used in plant science a variety of ways. The method molecular genome marking based on RAPD-PCR makes it possible to determine the genetic status populations and establish intrapopulation relationships. In this work, we studied polymorphism dandelion Taraxacum officionale using RAPD markers. Five random amplified polymorphic DNA (RAPD) were diversity relationship between tw...

Recognition of genetic reserves and desirable genes is the basis of breeding programs. So far, in Iran, due to the lack of recognition of genetic resources, a considerable breeding program has not been done on native plants. The study of the genetic diversity of violets as a native plant with ornamental and medicinal uses is the great importance in advancing the breeding goals of this plant. So...

wheat (triticum aestivum l.) is a major staple food crop for more than one third of the world population and is the main staple food of asia. over 800 million hectares of land throughout the world are salt affected. salinity is a major obstacle to food production because it substantially reduces the average yield of major crops. this study was conducted to evaluate the response of 24 cultivars ...

RAPD was used to delineate the hilsa populations sampled from the Ganga, Yamuna, Hooghly, and Narmada Rivers at six different locations. Six degenerate primers were used to generate the fragment patterns from the samples collected. All primers were highly polymorphic and generated high numbers of amplification products. Nei's genetic distances were calculated between locations. The overall aver...
