In order to identify polymorphic microsatellite markers and evaluae genetic variation within Baluchi sheep population, nineteen microsatellite loci were studied. Whole Blood samples were collected from 156 sheep at north eastern animal breeding station of Iran (Abbasabad-Mashhad). DNA was extracted by salting-out procedure with some modifications. Polymerase chain reactions were successfully do...

five subspecies of the persian jird, meriones persicus, were reported from iran. these subspecies were described based on morphological characters and coat colors of few specimens. the question of the validity of these subspecies and their geographic distribution is raised. in this study, we combined genetic markers (cox1, cytb and irbp genes), morphometric (external and skull measurments), mor...

Objective: Yield components and genetic contribution have the most important in final yield and breeding programs of crop plants. For this purpose, 20 varieties of grapevines with Russia origin were evaluated in Urmia and Takestan research station (under full irrigation and drought stress). Methods: Twenty grapevine genotypes were evaluated in Urmia and Takestan research station (under full irr...

Genetic diversity is the basis of breeding studies in many plant species and is one of the most important indicators for selecting parents. The aim of this experiment was to investigate the genetic diversity of tall fescue (Festuca arundinacea) using agronomic traits such as plant height, spring growth score, days to flowering, days to pollination, flag leaf length and width, panicle length, we...

designing breeding programs for winter rapeseed (brassica napus l.) cultivars with improved seed and oil yields requires information about the genetic variability of traits. in this study, 28 winter rapeseed cultivars were evaluated for genetic variation and relationships between 11 agro-morphological characters during 2010 and 2011. cultivars and cultivar × year interaction showed significant ...

The present study was carried out to determine population structure of Rutilus rutilus caspicus, one of the endemic species in the two region (Gorganrood and Anzali), with six microsatellite loci (Lc03، Lc04، Lid1، Cyp6، Ca1 and Ca3). sixty specimens of Rutilus rutilus caspicus were collected from Gorganrood and Bandaranzali (30 specimens for each population). according to the results, the Fst ...

Genetic variation among the individuals is considered as an important tool for conservation of livestock animals. This study was conducted to analyze the genetic variation, phylogenetic relationship and paternal lineages among Iranian dog populations using seventeen autosomal and Y chromosome-specific microsatellite markers. Total DNAs of the samples were extracted and applied for genotype anal...

drought is a major limiting factor for agricultural production in most parts of the world and landraces areimportant genetic resources for crop improvement in dry areas. during the 2007-2008 cropping season, 23 chickpea (cicer arietinum l.) genotypes consisting of 21 kabuli chickpea landraces provided by the national plant gene bank of iran and two known commercial varieties (hashem and arman) ...

Gestational weight gain (GWG) is a complex trait involving intrauterine environmental, maternal environmental, and genetic factors. However, the extent to which these factors contribute to the total variation in GWG is unclear. We therefore examined the genetic and environmental influences on the variation in GWG in the first and second pregnancy in monozygotic (MZ) and dizygotic (DZ) twin moth...
