in this study, length-weight relationship of three populations of fingerling roach (rutilus rutilus caspicus), wild, farmed and mix were investigated with the fish reproduce in the center of the proliferation of bony fish syjeval harber. in order to check the length-weight, 587 sample fish by hand sachook during the release into the sea. minimum and maximum total length of respectively 17.14 (f...
bream (abramis brama orientalis) is one of the most commercially valuable fish in the caspian sea. the aim of this study was to compare levels of genetic polymorphism between wild and farmed bream populations using seven microsatellite loci. genetic diversity was investigated by studying samples collected from two regions; chaboksar and the artificial propagation center of guilan province. alle...
Secale montanum is one of the important perennial grasses growingnaturally in arid to semiarid pastures and rangelands, with a typical Mediterraneanclimate, in northern and western Iran at altitudes of 800-2900 m. In this paper, seedstorage protein profiles of nine wild populations of S. montanum from differentregions of Iran and their phenotypically superior progenies as well as a multi-origin...
little information is available regarding genetic variation in wild wheat relatives from iran. in this study, genetic diversity of 36 populations of wild einkorn wheat, triticum boeoticum, was studied using amplified fragment length polymorphism (aflp) primer combinations. seventeen aflp primer combinations led to amplify 979 scorable fragments ranging from 50 to 500 bp and of these, 429 (44%) ...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Due to genetic erosion over evolution events, the genetic diversity of domesticated safflower species for drought tolerance is limited. Wild species has been considered as useful genetic resources for improvement of abiotic stress tolerance. In this study, a cultivated species (C. tinctorius) was crossed by two wild species (C. palaestinus and C. oxyacanthus) and the genotypes were purified unt...
The aim of this study was to investigate the body shape and morphological comparison between the populations of wild (marine) and farmed common carp using geometric morphology. For this purpose, 65 pieces of fish including 23 wild common carp and 42 farmed common carp were sampled. The samples were then photographed and 16 landmarks were identified on the images. Procrast analysis was used in o...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
to assess the genetic relationships between 72 cultivated and 65 wild grapevines in west azerbaijan and in kurdistan, 19 ssr markers were employed. microsatellitic primer pairs amplified, a total of 163 alleles with an average of 8.6 alleles/locus (for cultivars) and 153 alleles with an average of 8.05 alleles/locus (for wild samples). the expected heterozigosity varied from 0.7 in cultivars to...
Waxy proteins are responsible for amylase synthesis in wheat seeds, being encoded by three waxy genes (Wx-A1, Wx-B1 and Wx-D1) in hexaploid wheat which have an important role in starch quality. The purpose of this study was to investigate phylogenetic relationship between waxy genes in wild and cultivated wheat using Multiplex-PCR. To this end, 71 populations from 8 Aegilops and 4 wheat wild sp...
