in order to evaluate the effect of water deficit stress on agronomic and morpho-physiological traits in eight populations of the triticum urartu species an experiment was experiment was conducted using a split plot design based on a randomized complete block design with three replications at research station of faculty of agriculture, tabriz university in 2010-2011. analysis of variance indicat...
The present study aimed to compare traditional and geometric morphometrics to distinguish populations of Alburnus doriae in some Iranian basins. 132 specimens were collected and photographed. To remove effects of size, the general procrustes analysis was performed. Multivariate analysis of variance and procrustes analysis of variance were performed for traditional and geometric analyses. Both m...
inter simple sequence repeat (issr) markers were used to assess the genetic diversity among 23 outcross and self pollinated populations of fennel collected from different geographical regions of iran and some european countries. the experiment was carried out to determine the effect of self-pollination on morphological traits and genetic diversity in the next generation. fifteen primers produce...
Genotype imputation from low-density to high-density (SNP) chips is an important step before applying genomic selection, because denser chips can provide more reliable genomic predictions. In the current research, the accuracy of genotype imputation from low and moderate-density panels (5K and 50K) to high-density panels in the purebred and crossbred populations was assessed. The simulated popu...
The genus Ganoderma belongs to Polyporales, well-known for its medicinal properties and as a plant pathogen. The aim of this study was to identify the genetic variation between populations of two Ganoderma lucidum Karst. complex isolates using RAPD. For this purpose, four populations of G. resinaceum Boud. and eight populations of G. lucidum collected and purified during 2011-2012, were studied...
The present study was conducted on the comparison of morphometric and meristic factors among Alosa caspia (Eichwald, 1838) populations in the southern Caspian Sea basin. A total of 285 Alosa caspia specimens were caught from three localities, from west to the east of Caspian Sea including Guilan (Bandar Anzali), Mazandaran (Sari) and Golestan (Miankale) provinces. Thirty morphometric and ten me...
An important and fundamental step in breeding honeybees is the separation of honeybee populations in Iran. During the years 1992-1996, several research works were directed towards the investigation of genetic populations of the Iranian honeybee (Apis mellifera L.), using biochemical methods. For this purpose, samples of worker bees were taken from 251 colonies of 115 apiaries in 84 cities in 21...
Morphological similarities of the populations and species of the genus Ponticola in the southern Caspian Sea make their identification difficult based on the provided keys. Molecular markers are used as a supplementary tools to better understanding of the fishes’ taxonomic statues. This study was conducted to understand taxonomic statues of gobiids from 6 rivers (Siah, Zaringol, Babol, Tajan, S...
There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...
this study compares diversity patterns of five microsatellite (ssr) markers in two iranian native horse populations (turkoman sahra and turkoman jergelan) to infer relationships between them and to compare levels of their polymorphism for use in conservation efforts. two populations across microsatellite loci had significant deviations from hardy-weinberg equilibrium. average number of alleles ...
