An analysis of eight microsatellite loci in 90 individuals was performed to define the genetic structure and variability of three estuarine populations of Coilia mystus: 30 individuals each collected from ChangJiang River (Yangtze River) estuary-CJ, MinJiang River estuary-MJ, and ZhuJiang River (Pearl River) estuary-ZJ. The results showed polymorphic information contents (PIC) of 0.78, 0.77, a...
Genetic male sterility is controlled by one pair of ressesive allele (aa) in sugar beet. This trait is used in most breeding programes. The exsistance of the character in a line or population facilitates transfer of important trait to the breeding material (for example resistance to plant disease). Also, it is possible to increase genetic diversity of monogerm populations by using genetic ma...
The experiment was conducted in 2012 to evaluate the effect of salinity stress on oil percent, oil yield, seed yield and some physiological charactristics on three local populations of castor bean (Ricinus communis L.), at the University of Shahrekord, Iran. Experiment was carried out with three replications in a completely randomized design including five levels of salinity (1.2, 2, 2.6, 3.8 ...
This study represents a large-scale population genetic analysis of the stellate sturgeon, Acipenser stellatus, in the Caspian Sea. In total, 192 samples of adult stellate sturgeon were collected from four commercial catch stations in the Northern (Volga and Ural Rivers) and Southern Caspian Sea (estuary of Sefidrud and Gorganrod Rivers-Iran). Fifteen sets of microsatellite primers developed fro...
. In this study, morphological variation of three species of Squalius in Iranian basins was studied. For this purpose, 709 specimens were captured from the Caspian Sea, the Urmia Lake, the Namak Lake and the Tigris basin. After anesthetizing in clove oil solution and fixing in 10% neutralized formalin, specimens were transferred to the Isfahan University of Technology Ichthyology Museum (IUT-IM...
In order to study the genetic variation among local varieties of onion in Iran, an experiment was conducted in the Research Center, Faculty of Agriculture, Tabriz University. Sixteen populations were evaluated for agronomic characteristics and also total seed proteins via SDS-PAGE. Cluster analysis and principal component analysis were used to group the onion populations under study. Analysis o...
Genetic variation within and between five Iranian sheep populations including Sanjabi (SAN), Kordi Kordistan (KKO), Kordi Khorasan (KKH), Mehraban (MEH) and Moghani (MOG) was assessed using six microsatellite markers (McMA2, McMA26, MAF64, OarAE64, OarCP26 and OarFCB304). The PCR reactions were successfully perfomed with all primers except OarAE64. All locus-population combinations were at Hard...

in this study, some of biological parameters of vimba vimba from february 2009 to june 2010 were examined. in total, 281 fish samples were caught by gill- net. in two regions had of five age groups that, the most frequent age groups were related to 2+. sex ratio of male to female were in gorganrud population 67% ? to 33% ? and in mahmoudabad population 57% ? to 43% ? (p?0.05). there was no sign...
the aim of the present study was the genetic analysis of the dniester population of sterlet acipenser ruthenus and comparison of it to five other sterlet populations, in order to develop a population recovery plan. the genetic analysis of six sterlet populations from eurasian rivers (dniester, dnieper, danube, volga, kama and ob) was carried out using microsatellite dna markers. the genetic var...
